Title:
PHOTOCATALYST MEMBER
Document Type and Number:
WIPO Patent Application WO/2023/190230
Kind Code:
A1
Abstract:
According to an aspect of the present invention, provided is a photocatalyst member comprising a photocatalyst layer formed on a base material via a foundation layer, the photocatalyst member being characterized in that the foundation layer at least has a cerium oxide, and the photocatalyst layer at least has a titanium oxide. Here, the foundation layer may comprise only a cerium oxide, or may comprise a cerium oxide and at least one or more other types of elements having a cerium element ratio of 10 atom% or less. According to the present invention, it is possible to produce a photocatalyst with high industrial productivity.
