    Abstract Porous functional organic polymers have attracted significant interest due to their diverse applications in adsorption/separation, electrocatalysis, photocatalysis, photosensing, and electronics. In these applications, performance depends on interactions between guest molecules and polymer frameworks. Consequently, the introduction of mesopores (2–50 nm) and macropores (50–300 nm) can significantly enhance functionality by simultaneously increasing the exposed active surface area and facilitating molecular diffusion within the polymer matrix. However, a wide range of porous polymers achievable through previous approaches, including surfactant and polystyrene templating, has been severely limited to a few less functional polymers due to the typically aqueous environment used during templating reaction and the need for template removal after polymerization. In this work, a universal approach is demonstrated that utilizes water‐soluble templates to synthesize functional meso‐ and macro‐porous organic polymers via solid‐state polymerization of aldehydes and amines (Schiff reaction), using perovskite metal fluorides (K M F 3 ) as sacrificial templates. By precisely tuning the particle sizes of metal fluoride templates, accurate control over pore sizes across the mesoscopic and macroscopic scales is achieved. A variety of aldehyde‐amine combinations yield semiconductive meso‐ and macro‐porous organic polymers. This versatile synthetic strategy is broadly applicable to a wide range of polymer systems, enabling simultaneous enhancement of surface area and molecular diffusion, thereby optimizing functional performance.

    ConspectusPhotocatalytic and photoelectrochemical CO2 reduction of artificial photosynthesis is a promising chemical process to solve resource, energy, and environmental problems. An advantage of artificial photosynthesis is that solar energy is converted to chemical products using abundant water as electron and proton sources. It can be operated under ambient temperature and pressure. Especially, photocatalytic CO2 reduction employing a powdered material would be a low-cost and scalable system for practical use because of simplicity of the total system and simple mass-production of a photocatalyst material.In this Account, single particulate photocatalysts, Z-scheme photocatalysts, and photoelectrodes are introduced for artificial photosynthetic CO2 reduction. It is indispensable to use water as an electron donor (i.e., reasonable O2 evolution) but not to use a sacrificial reagent of a strong electron donor, for achievement of the artificial photosynthetic CO2 reduction accompanied by ΔG > 0. Confirmations of O2 evolution, a ratio of reacted e- to h+ estimated from obtained products, a turnover number, and a carbon source of a CO2 reduction product are discussed as the key points for evaluation of photocatalytic and photoelectrochemical CO2 reduction.Various metal oxide photocatalysts with wide band gaps have been developed for water splitting under UV light irradiation. However, these bare metal oxide photocatalysts without a cocatalyst do not show high photocatalytic CO2 reduction activity in an aqueous solution. The issue comes from lack of a reaction site for CO2 reduction and competitive reaction between water and CO2 reduction. This raises a key issue to find a cocatalyst and optimize reaction conditions defining this research field. Loading a Ag cocatalyst as a CO2 reduction site and NaHCO3 addition for a smooth supply of hydrated CO2 molecules as reactant are beneficial for efficient photocatalytic CO2 reduction. Ag/BaLa4Ti4O15 and Ag/NaTaO3:Ba reduce CO2 to CO as a main reduction reaction using water as an electron donor even in just water and an aqueous NaHCO3 solution. A Rh-Ru cocatalyst on NaTaO3:Sr gives CH4 with 10% selectivity (Faradaic efficiency) based on the number of reacted electrons in the photocatalytic CO2 reduction accompanied by O2 evolution by water oxidation.Visible-light-responsive photocatalyst systems are indispensable for efficient sunlight utilization. Z-scheme systems using CuGaS2, (CuGa)1-xZn2xS2, CuGa1-xInxS2, and SrTiO3:Rh as CO2-reducing photocatalyst, BiVO4 as O2-evolving photocatalyst, and reduced graphene oxide (RGO) and Co-complex as electron mediator or without an electron mediator are active for CO2 reduction using water as an electron donor under visible light irradiation. These metal sulfide photocatalysts have the potential to take part in Z-scheme systems for artificial photosynthetic CO2 reduction, even though their ability to extract electrons from water is insufficient.A photoelectrochemical system using a photocathode is also attractive for CO2 reduction under visible light irradiation. For example, p-type CuGaS2, (CuGa)1-xZn2xS2, Cu1-xAgxGaS2, and SrTiO3:Rh function as photocathodes for CO2 reduction under visible light irradiation. Moreover, introducing a conducting polymer as a hole transporter and surface modification with Ag and ZnS improve photoelectrochemical performance.

    We demonstrated photocatalytic CO2 reduction using water as an electron donor under visible light irradiation by a Z-scheme photocatalyst and a photoelectrochemical cell using bare (CuGa)0.5ZnS2 prepared by a flux method as a CO2-reducing photocatalyst. The Z-scheme system employing the bare (CuGa)0.5ZnS2 photocatalyst and RGO-(CoOx/BiVO4) as an O2-evolving photocatalyst produced CO of a CO2 reduction product accompanied by H2 and O2 in a simple suspension system without any additives under visible light irradiation and 1 atm of CO2. When a basic salt (i.e., NaHCO3, NaOH, etc.) was added into the reactant solution (H2O + CO2), the CO formation rate and the CO selectivity increased. The same effect of the basic salt was observed for sacrificial CO2 reduction using SO32- as an electron donor over the bare (CuGa)0.5ZnS2 photocatalyst. The selectivity for the CO formation of the Z-schematic CO2 reduction reached 10-20% in the presence of the basic salt even in an aqueous solution and without loading any cocatalysts on the (CuGa)0.5ZnS2 metal sulfide photocatalyst. It is notable that CO was obtained accompanied by reasonable O2 evolution, indicating that water was an electron donor for the CO2 reduction. Moreover, the present Z-scheme system also showed activity for solar CO2 reduction using water as an electron donor. The bare (CuGa)0.5ZnS2 powder loaded on an FTO glass was also used as a photocathode for CO2 reduction under visible light irradiation. CO and H2 were obtained on the photocathode with 20% and 80% Faradaic efficiencies at 0.1 V vs RHE, respectively.

    (CuGaS2)-(ZnS)をフラックス法により調製し，数百nm-数μmの範囲で，ある程度サイズを制御したサンプルを得た．数百nmの金属硫化物微粒子は，RGO-CoOx/BiVO4を酸素生成光触媒に用いたZスキーム型光触媒系のみならず，ドロップキャスト法により作成する金属硫化物光カソードを用いた光電気化学系の高性能化にも有効であることを見いだした．フラックス法で合成した本金属硫化物微粒子を用いて光電気化学的二酸化炭素還元を行ったところ，水素と一酸化炭素の混合ガスがカソードセルから得られた．そして，本光カソードは，従来のCuGaS2を元とする金属硫化物光カソードよりも安定に駆動することがわかった． SrTiO3:RhおよびBiVO4を懸濁させて可視光二酸化炭素還元も行なった．その結果，水分解の水素と酸素の生成に加えて二酸化炭素還元生成物である一酸化炭素が得られた．そして，AuおよびAgをSrTiO3:Rhへ担持すると一酸化炭素生成活性が向上した．本Zスキーム型二酸化炭素還元に対するpH依存性を確認したところ，pH4付近においてZスキーム型二酸化炭素還元が進行し，中性および強酸性条件ではほとんど反応が進行しなかった．反応後の粒子懸濁状態を光学顕微鏡で観察すると，pH4付近ではSrTiO3:RhとBiVO4が凝集していたのに対し，中性および強酸性では凝集がみられなかった．そのため，粒子の凝集がZスキーム型二酸化炭素還元の進行に重要であることがわかった．また，SrTiO3:Rhを光カソードに用いた光電気化学的可視光二酸化炭素還元も進行した．さらにSrをCaで置換した光カソードを用いることで，CO生成選択率が向上することがわかった．
