The first conductive layer is interposed between the substrate and the first semiconductor photocatalyst layer. At least a part of the first semiconductor photocatalyst layer is in contact with the liquid. At least a part of the counter electrode is in contact with the liquid. The liquid is selected from the group consisting of an electrolyte aqueous solution and water. The substrate is formed of a resin.
摘要:
If a conductive mayenite compound having a large specific surface area is obtained, the usefulness thereof in respective applications is remarkably increased. A conductive mayenite compound powder having a conduction electron density of 1015 cm−3 or more and a specific surface area of 5 m2g−1 or more is produced by: (1) a step for forming a precursor powder by subjecting a mixture of a starting material powder and water to a hydrothermal treatment; (2) a step for forming a mayenite compound powder by heating and dehydrating the precursor powder; (3) a step for forming an activated mayenite compound powder by heating the compound powder in an inert gas atmosphere or in a vacuum; and (4) a step for injecting electrons into the mayenite compound through a reduction treatment by mixing the activated mayenite compound powder with a reducing agent.
