Abstract

The Cu- and Ti-containing composition of the present invention contains titanium oxide having a rutile-type titanium oxide content of 15 mol % or more, and at least one divalent copper compound represented by the following formula (1). The Cu- and Ti-containing composition production method of the present invention is characterized by including stirring a mixture containing titanium oxide having a rutile-type titanium oxide content of 15 mol % or more, a divalent copper compound raw material represented by formula (2), water, and an alkaline compound, to thereby cause precipitation. The composition of the present invention exhibits excellent anti-viral property under light and in the dark, and excellent organic compound decomposition activity under light.
