PHOTOCATALYST PRODUCTION METHOD, PHOTOCATALYST OBTAINED BY THE METHOD, AND USE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a production method of a metal oxide photocatalyst exhibiting a high catalyst activity even to visible light rays and in which the dispersion state and deposition amount of silver halide is controlled, and a photocatalyst produced by the production method. SOLUTION: The photo catalyst production method for producing a photocatalyst containing silver bromide, i.e., the photocatalyst production method comprising a dispersion step of dispersing silver bromide in silica sol and/or silica gel derived from silicon alkoxide and is capable of providing a photocatalyst showing a high activity to ultraviolet rays and visible light rays.
