Abstract
A titanium compound for photochemical reactions having a high catalytic activity per unit surface area and extremely good stability to heat treatment is made of a substitutional solid solution of titanium oxide in which aluminum atoms occupy titanium sites of the titanium oxide uniformly at a predetermined ratio. Aluminum atoms preferably occupy about 0.01 to 0.5% of the titanium sites. The titanium compound for photochemical reactions is obtained from a complex alkoxide of titanium and aluminum.
