PHOTOCHEMICAL REACTION DEVICE

摘要

According to one embodiment, a photochemical reaction device comprises a laminated body and an ion transfer pathway. A laminated body comprises an oxidation catalyst layer for producing oxygen and protons by oxidizing water a reduction catalyst layer for producing carbon compounds by reducing carbon dioxide and a semiconductor layer formed between the oxidation catalyst layer and the reduction catalyst layer and developing charge separation with light energy. An ion transfer pathway moves ions between the oxidation catalyst layer side and the reduction catalyst layer side.
