PHOTOCATALYST MATERIAL AND ITS PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an apatite, displaying a new photocatalyst function by improving a catalyst function of this apatite and also keeping excellent absorption properties of it over a long term. SOLUTION: The apatite is formed by coprecipitation and also is structured so that a metal oxide having the photocatalyst function is formed in a crystalline structure of the apatite by ion exchange.
