Abstract:
1. A Cu- and Ti-containing composition comprising titanium oxide including rutile-crystal-type titanium oxide, and a divalent copper compound, wherein the rutile-crystal-type titanium oxide exhibits the most intense diffraction peak attributed to rutile-type titanium oxide having a full width at half maximum of 0.65° or less, in a Cu—Kα line X-ray diffraction pattern, which is obtained by plotting intensity of diffraction line with respect to diffraction angle 2θ, wherein the rutile-crystal-type titanium oxide content of titanium oxide is 50 mol % or more and the anatase-type titanium oxide content of titanium oxide is less than 50 mol %, wherein the titanium oxide has a specific surface area of 8 to 50 m wherein the divalent copper compound is deposited on a surface of the titanium oxide, wherein a copper content, as reduced to elemental copper, of the divalent copper compound is 0.3 to 10 parts by mass with respect to 100 parts by mass of titanium oxide, and wherein the titanium oxide has a rutile-crystal-type titanium oxide content of 90 mol % or more.
