Photochemical reaction device

摘要

This photochemical reaction device is provided with: a laminate body comprising an oxidation catalyst layer (19) which oxidizes water to generate oxygen and protons, a reduction catalyst layer (20) which reduces carbon dioxide to generate a carbon compound, and a semiconductor layer (17) which is formed between the oxidation catalyst layer and the reduction catalyst layer and which performs charge separation by means of light energy; and an ion transfer path for transferring ions between the oxidation catalyst layer side and the reduction catalyst layer side.
