Abstract

A copper compound-carried titanium oxide photocatalyst which is excellent in a photocatalytic activity and a viral inactivation property and a production process for the same can be provided by a copper compound-carried titanium oxide photocatalyst comprising titanium oxide in which a content of rutile type titanium oxide is 50% by mole or more and a monovalent copper compound and a divalent copper compound which are carried on a surface of the titanium oxide described above and a production process for a copper compound-carried titanium oxide photocatalyst, comprising a step of carrying a monovalent copper compound and a divalent copper compound on a surface of titanium oxide in which a content of rutile type titanium oxide is 50% by mole or more.
