    Abstract Many perovskite oxides (ABO3) are considered the most promising alternatives to noble metal catalysts for oxygen reduction reaction (ORR) due to their high intrinsic activities. However, their electrocatalytic performance is often limited by poor electrical conductivity and low specific surface area. Here an electrochemically induced calcium‐leaching process is reported to greatly increase the electrochemical surface area (ECSA) of La0.6Ca0.4MnO3 (LCMO64). The ECSA of the activated, Ca‐deficient LCMO64 is ≈33.84% higher than that of the unactivated materials, demonstrating superior electrocatalytic ORR performance to the benchmark commercial Pt/C catalyst in an alkaline solution. Theoretical analysis coupled with electrochemical surface state probing and pH‐dependent microkinetic modeling suggests that this catalyst with the identified most favorable state under ORR operating conditions reaches the Sabatier optimum of alkaline ORR. This reconstructed LCMO64 is among the best‐performing ORR catalysts ever reported, providing new insights into the design of advanced perovskite materials with optimal surface chemistry.

    Phthalocyanines (Pcs) have garnered significant attention as promising catalysts for electrochemical CO2 reduction (ECR); however, traditional methods for preparing carbon-supported Pcs are often complex and time-consuming, limiting their industrial applicability. Herein, a rapid spray-growth method is introduced that directly deposits CoPc crystals onto carbon paper (CP) in just 15 min. The resulting CoPc/CP electrode maintains > 90% CO selectivity across a broad ECR window (-0.57 to -1.32 V vs RHE), achieves a record-breaking CO current density of -1034 mA cm-2, an ultrahigh mass activity of 5180 A g-1, and demonstrates excellent long-term stability (145 h @ -150 mA cm-2), surpassing all reported Pc-based catalysts. Comprehensive characterization attributes this high performance to its carbon-supported-crystalline structure and surface charge transfer (SCT). Density functional theory (DFT) calculations further reveal that even minimal SCT effectively optimizes the adsorption energies of key intermediates (*CO and *COOH), thereby significantly enhancing intrinsic activity. Moreover, this spray-grown electrode offers unique structural advantages, such as strong substrate adhesion and internal layers that replenish active sites-features absent in traditional carbon-supported electrodes. It is believed that this facile spray-growth method holds broad potential and enables the application of additional Pc-based materials for industrial-scale ECR.

    The design principles for metal‐nitrogen‐carbon (M‐N‐C) single‐atom catalysts (SACs) in the hydrogen evolution reaction (HER) have been extensively studied. While hydrogen binding energy ([[EQUATION]]) has long been used as a HER descriptor during the past decades, its applicability to HER SACs has been met with significant controversy. Herein, we investigate the effects of HO*/O* poisoning and H* coverage on SACs with varied metal centers and coordination environments using pH‐dependent surface Pourbaix diagrams at the reversible hydrogen electrode (RHE) scale and microkinetic modeling. Our findings reveal that HO* poisoning, realistic H* adsorption strengths at active metal sites, and the potential HER activity at the coordinating N‐sites are crucial factors that should be considered for accurate descriptor development. Experimental validation using a series of M‐phthalocyanine/CNT catalysts confirms the theoretical predictions, with excellent agreement in exchange current densities and the role of N‐sites in Ni/Cu‐phthalocyanine/CNT catalysts. More importantly, the controversy surrounding HER SAC design principles is resolved through a novel 2D microkinetic volcano model that incorporates active sites, H* coverage, and HO* poisoning. This work provides answers to a long‐lasting debate on HER descriptors by establishing [[EQUATION]] and [[EQUATION]] as a combined HER descriptor for SACs, offering new guidelines for catalyst design.

    Abstract The development of advanced catalysts frequently employs trial‐and‐error methods and is lack of highly controlled synthesis, resulting in unsatisfactory development efficiency and performance. Here we propose a data‐driven prediction coupled with precise synthesis strategy to accelerate the development of single‐atom catalysts (SACs) for efficient water purification. The data‐driven approach enables the rapid screening and prediction of high‐performance SACs from 43 metals‐N4 structures comprising transition and main group metal elements, followed by validation and structural modulation for improved performance through a highly controllable hard‐template method. Impressively, a well‐designed Fe‐SAC with a high loading of Fe‐pyridine‐N4 sites (~3.83 wt %) and highly mesoporous structure, exhibits ultra‐high decontamination performance (rate constant of 100.97 min−1 g−2), representing the best Fenton‐like activities for sulfonamide antibiotics to date. Furthermore, the optimized Fe‐SAC shows excellent robust environmental resistance and cyclic stability with almost 100 % degradation efficiency of sulfonamide antibiotics for 100‐h continuous operation. Density functional theory calculations reveal that Fe‐pyridine‐N4 sites can reduce the energy barrier of intermediate O* formation, the rate‐determining step, resulting in highly selective generation of singlet oxygen. The integration of data‐driven method with precise synthesis strategy provides a novel paradigm for the rapid development of high‐performance catalysts for environmental field as well as other important fields including sustainable energy and catalysis.

    Abstract The rational design of efficient electrocatalysts with controllable structure and composition is crucial for enhancing the lifetime and cost‐effectiveness of oxygen reduction reaction (ORR). PtCo nanocrystals have gained attention due to their exceptional activity, yet suffer from stability issues in acidic media. Herein, an active and highly stable electrocatalyst is developed, namely 3D Pt7Co3@Pt core‐shell nanodendrites (NDs), which are formed through the self‐assembly of small Pt nanoparticles (≈6 nm). This unique structure significantly improves the ORR with an enhanced mass activity (MA) of 0.54 A mgPt−1, surpassing that of the commercial Pt/C (com‐Pt/C) catalyst by three fold (0.17 A mgPt−1). The well‐organized dendritic morphology, along with the Pt‐rich shell, contributes significantly to the observed high catalytic activity and superior stability for acidic ORR, which exhibit a loss of 2.1% in MA and, impressively, an increase of 12.0% in specific activity (SA) after an accelerated durability test (ADT) of 40,000 potential‐scanning cycles. This work offers insights for improving the design of highly stable Pt‐based electrocatalysts for acidic ORR.

    Abstract As the demand for cleaner energy becomes a paramount objective of sustainable development, the advancement of cutting‐edge engineered materials for a wide range of applications becomes increasingly vital. Tailoring catalyst properties through precise design and electronic state tuning is essential for adapting these materials to large‐scale energy applications. Given this, an effective electronic fine‐tuning (EFT) strategy is presented to optimize the electronic structures of single‐atom Zn site and Ru species, synergistically enhancing the both electrocatalytic oxygen reduction reaction (ORR) and hydrogen evolution reaction (HER). Benefiting from the interaction between Ru species anchored on hierarchically layered nanosheets and isolated Zn atoms (Ru@Zn‐SAs/N‐C), the catalyst exhibits superior ORR and HER activities compared to the benchmark Pt/C catalyst. X‐ray absorption spectroscopy and density functional theory (DFT) calculations confirm a novel EFT effect between a single Zn site and Ru species, that enables the Ru@Zn‐SAs/N‐C approaches the optimal scaling relation between *OOH and *OH, breaking the universal ORR scaling limitation. Additionally, the optimal GH* value positions Ru@Zn‐SAs/N‐C near the apex of the theoretical HER volcano model. This work provides an innovative avenue for regulating the electronic localization of catalytic active centers by virtue of carbon substrate and offers valuable insights for designing high‐efficiency electrocatalysts.

    Abstract Tin (Sn)‐based catalysts have been widely studied for electrochemical CO2 reduction reaction (CO2RR) to produce formic acid, but the intricate influence of the structural sensitivity in single‐atom Sn (e.g., Sn−N−C) and polyatomic Sn (e.g., SnOx and SnSx; x=1,2) on their pH‐dependent performance remains enigmatic. Herein, we integrate large‐scale data mining (with >2,300 CO2RR catalysts from available experimental literature during the past decade), ab initio computations, machine learning force field accelerated molecular dynamic simulations, and pH‐field coupled modelling to unravel their pH dependence. We reveal a fascinating contrast: the electric field response of the binding strength of *OCHO on Sn−N4−C and polyatomic Sn exhibits opposite behaviors due to their differing dipole moment changes upon *OCHO formation. Such response leads to an intriguing opposite pH‐dependent volcano evolution for Sn−N4−C and polyatomic Sn. Subsequent experimental validations of turnover frequency and current density under both neutral and alkaline conditions well aligned with our theoretical predictions. Most importantly, our analysis suggests the necessity of distinct optimization strategies for *OCHO binding energy on different types of Sn‐based catalysts.

    Abstract Proton-exchange-membrane fuel cells demand highly efficient catalysts for the oxygen reduction reaction, and core-shell structures are known for maximizing precious metal utilization. Here, we reported a controllable “carbon defect anchoring” strategy to prepare Pt1Ni1@Pt/C core-shell nanoparticles with an average size of ~2.6 nm on an in-situ transformed defective carbon support. The strong Pt–C interaction effectively inhibits nanoparticle migration or aggregation, even after undergoing stability tests over 70,000 potential cycles, resulting in only 1.6% degradation. The stable Pt1Ni1@Pt/C catalysts have high oxygen reduction reaction mass activity and specific activity that reach 1.424 ± 0.019 A/mgPt and 1.554 ± 0.027 mA/cmPt2 at 0.9 V, respectively, attributed to the optimal compressive strain. The experimental results are generally consistent with the theoretical predictions made by our comprehensive microkinetic model which incorporates essential kinetics and thermodynamics of oxygen reduction reaction. The consistent results obtained in our study provide compelling evidence for the high accuracy and reliability of our model. This work highlights the synergy between theory-guided catalyst design and appropriate synthetic methodologies to translate the theory into practice, offering valuable insights for future catalyst development.

    Abstract Understanding the spin‐dependent activity of nitrogen‐coordinated single metal atom (M‐N‐C) electrocatalysts for oxygen reduction and evolution reactions (ORR and OER) remains challenging due to the lack of structure‐defined catalysts and effective spin manipulation tools. Herein, both challenges using a magnetic field integrated heterogeneous molecular electrocatalyst prepared by anchoring cobalt phthalocyanine (CoPc) deposited carbon black on polymer‐protected magnet nanoparticles, are addressed. The built‐in magnetic field can shift the Co center from low‐ to high‐spin (HS) state without atomic structure modification, affording one‐order higher turnover frequency, a 50% increased H2O2 selectivity for ORR, and a ≈4000% magnetocurrent enhancement for OER. This catalyst can significantly minimize magnet usage, enabling safe and continuous production of a pure H2O2 solution for 100 h from a 100 cm2 electrolyzer. The new strategy demonstrated here also applies to other metal phthalocyanine‐based catalysts, offering a universal platform for studying spin‐related electrochemical processes.

    Abstract C–H bond activation enables the facile synthesis of new chemicals. While C–H activation in short-chain alkanes has been widely investigated, it remains largely unexplored for long-chain organic molecules. Here, we report light-driven C–H activation in complex organic materials mediated by 2D transition metal dichalcogenides (TMDCs) and the resultant solid-state synthesis of luminescent carbon dots in a spatially-resolved fashion. We unravel the efficient H adsorption and a lowered energy barrier of C–C coupling mediated by 2D TMDCs to promote C–H activation and carbon dots synthesis. Our results shed light on 2D materials for C–H activation in organic compounds for applications in organic chemistry, environmental remediation, and photonic materials.

    Abstract Data mining from computational materials database has become a popular strategy to identify unexplored catalysts. Herein, the opportunities and challenges of this strategy are analyzed by investigating a discrepancy between data mining and experiments in identifying low‐cost metal oxide (MO) electrocatalysts. Based on a search engine capable of identifying stable MOs at the pH and potentials of interest, a series of MO electrocatalysts is identified as potential candidates for various reactions. Sb2WO6 attracted the attention among the identified stable MOs in acid. Based on the aqueous stability diagram, Sb2WO6 is stable under oxygen reduction reaction (ORR) in acidic media but rather unstable under high‐pH ORR conditions. However, this contradicts to the subsequent experimental observation in alkaline ORR conditions. Based on the post‐catalysis characterizations, surface state analysis, and an advanced pH‐field coupled microkinetic modeling, it is found that the Sb2WO6 surface will undergo electrochemical passivation under ORR potentials and form a stable and 4e‐ORR active surface. The results presented here suggest that though data mining is promising for exploring electrocatalysts, a refined strategy needs to be further developed by considering the electrochemistry‐induced surface stability and activity.

    Abstract The active‐site density, intrinsic activity, and durability of Pd−based materials for oxygen reduction reaction (ORR) are critical to their application in industrial energy devices. This work constructs a series of carbon‐based rare‐earth (RE) oxides (Gd2O3, Sm2O3, Eu2O3, and CeO2) by using RE metal–organic frameworks to tune the ORR performance of the Pd sites through the Pd−RExOy interface interaction. Taking Pd−Gd2O3/C as a representative, it is identified that the strong coupling between Pd and Gd2O3 induces the formation of the Pd−O−Gd bridge, which triggers charge redistribution of Pd and Gd2O3. The screened Pd−Gd2O3/C exhibits impressive ORR performance with high onset potential (0.986 VRHE), half‐wave potential (0.877 VRHE), and excellent stability. Similar ORR results are also found for Pd−Sm2O3/C, Pd−Eu2O3/C, and Pd−CeO2/C catalysts. Theoretical analyses reveal that the coupling between Pd and Gd2O3 promotes electron transfer through the Pd−O−Gd bridge, which induces the antibonding‐orbital occupancy of Pd−*OH for the optimization of *OH adsorption in the rate‐determining step of ORR. The pH‐dependent microkinetic modeling shows that Pd−Gd2O3 is close to the theoretical optimal activity for ORR, outperforming Pt under the same conditions. By its ascendancy in ORR, the Pd−Gd2O3/C exhibits superior performance in Zn‐air battery as an air cathode, implying its excellent practicability.
