(57) [Summary] (Problem corrected) [Problem] A functional complex or molding whose surface exhibits controllability of water wettability (hydrophilicity, hydrophobicity) and / or photocatalytic activity for a long time by light irradiation Provided is a photocatalytic material from which a body can be obtained. The modified photocatalyst is obtained by modifying a photocatalyst with a Si-H group-containing compound represented by the formula (1). And a photocatalyst composition comprising the modified photocatalyst and a resin. (Wherein, R 1 , R 2 and R 3 are each independently a linear or branched alkyl or alkenyl group having 1 to 30 carbon atoms, a cycloalkyl group having 5 to 20 carbon atoms, No or an alkyl or alkoxy group having 1 to 20 carbon atoms, or 6 to 6 carbon atoms substituted with a halogen atom 20 aryl groups or siloxy groups represented by the formula (2). ) -O- (R 4 R 4 SiO ) a-SiR 4 R 4 R 4 (2) |
