A three‐dimensional reaction field composed of a thick, porous TiO₂ layer decorated with Pt and an anionic ionomer was fabricated on the surface of a membrane photocathode assembly (MPA). This MPA comprised (ZnSe)_0.85(CuIn_0.7Ga_0.3Se₂)_0.15 (ZnSe : CIGS) particles that promoted the photoelectrochemical (PEC) production of methylcyclohexane (MCH) from toluene and water. The Pt/TiO₂ layer provided selective active sites for MCH production as well as reactant supply pathways. A tandem PEC cell consisting of the Pt/TiO₂‐modified ZnSe : CIGS MPA and a photoanode exhibited spontaneous MCH production with a solar‐to‐MCH (STMCH) conversion efficiency as high as 0.32 %. This is the first‐ever report of sunlight‐driven overall MCH production without any assistance of external bias voltages and demonstrates the feasibility of driving this reaction as an artificial photosynthesis.

ZnSe：Cu（In，Ga）Se2基光电阴极在阳光下由水和甲苯生产甲基环己烷

在膜光电阴极组件（MPA）的表面上制作了一个三维反应场，该场由厚的多孔TiO ₂层和Pt装饰而成，并带有阴离子离聚物。该MPA包含（ZnSe）_0.85（CuIn _0.7 Ga _0.3 Se ₂）_0.15（ZnSe：CIGS）颗粒，这些颗粒促进了甲苯和水的光化学（PEC）生产甲基环己烷（MCH）。Pt / TiO ₂层为MCH生产以及反应物供应途径提供了选择性的活性位点。由Pt / TiO ₂组成的串联式PEC电池改性的ZnSe：CIGS MPA和光阳极表现出自发的MCH生成，太阳能到MCH（STMCH）的转换效率高达0.32％。这是有史以来关于阳光驱动的整个MCH生产的第一份报告，没有任何外部偏置电压的辅助，证明了将该反应作为人工光合作用进行驱动的可行性。
