SILICA-TITANIA COMPOSITE AEROGEL PARTICLE, METHOD FOR PRODUCING SILICA-TITANIA COMPOSITE AEROGEL PARTICLE, PHOTOCATALYST-FORMING COMPOSITION, PHOTOCATALYST AND STRUCTURE

摘要

To provide a silica titanium composite aerogel particle that exhibits a high photocatalytic function in the visible range.SOLUTION: A silica-titania composite aerogel particle includes a base particle with an element ratio of silicon and titanium, Si/Ti, of more than 0 and 6 or less. The silica-titania composite aerogel particle has a BET specific surface area in the range of 200 m/g to 1,200 m/g, and has absorption at wavelengths of 450 nm and 750 nm in a visible absorption spectrum.SELECTED DRAWING: None
