METHOD FOR PRODUCING JUNCTION PHOTOCATALYST, AND JUNCTION PHOTOCATALYST

Abstract: the present invention provides a method for producing a heterojunction photocatalyst having higher catalytic activity than that of conventional heterojunction photocatalysts, and a heterojunction photocatalyst. a method for producing a heterojunction photocatalyst having a solid state mediator between a hydrogen-evolution photocatalyst and an oxygen-evolution photocatalyst, which includes the following step 1: step 1: a step of joining the solid state mediator onto the oxygen-evolution photocatalyst by at least one method selected from the group consisting of a photoelectrodeposition method, an impregnation supporting method, and a precipitation method, in each of which an organic carboxylic acid compound and a solid state mediator or a precursor of the solid state mediator are used.
