Abstract: A silica-titania composite has a BET specific surface area, as determined by BET analysis of a water vapor adsorption isotherm, in the range of 250 m2/g to 500 m2/g and a contact angle with water of 100° or greater. In the water vapor adsorption isotherm, an adsorbed amount at relative pressure P/P0=0.1 is in a range of 65 cm3/g to 120 cm3/g, an adsorbed amount at relative pressure P/P0=0.5 is in a range of 150 cm3/g to 300 cm3/g, and an adsorbed amount at relative pressure P/P0=0.9 is in a range of 350 cm3/g to 500 cm3/g.

Abstract: A filter includes a filter medium having an average pore size of 1 to 5 mm, and photocatalyst particles deposited on the filter medium. The photocatalyst particle contains a titanium compound particle and a metal compound bonded to the surface of the titanium compound particle with an oxygen atom. The metal compound contains a metal atom and a hydrocarbon group. The titanium compound particle has absorption at wavelengths of 450 nm and 750 nm in the visible absorption spectrum of the titanium compound particle.
