Japanese Patent JP2023127571
Kind Code:
A
Abstract:
To provide: a method for producing a junction photocatalyst that has higher catalytic activity than conventional junction photocatalysts; and a contact type photocatalyst.SOLUTION: The present invention provides a method for producing a junction photocatalyst that has a solid mediator between a hydrogen generation photocatalyst and an oxygen generation photocatalyst, the method comprising the step 1 described below. Step 1: A step in which a solid mediator is joined onto an oxygen generation photocatalyst by at least one method that is selected from the group consisting of a photoelectrodeposition method, an impregnation deposition method and a precipitation method, the methods using an organic carboxylic acid compound and the solid mediator or a precursor thereof.SELECTED DRAWING: None
