SILICATE-COATED TITANIUM OXIDE MATERIAL FOR DECOMPOSING VOLATILE ORGANIC COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide a silicate-coated silicate-titanium oxide material for decomposing volatile organic compounds. SOLUTION: A method produces an inorganic silicate-titanium oxide composite, where an inorganic silicate is coated on the surface of a base material having a surface comprising titanium oxide, which comprises mixing a silicon compound aqueous solution and an aqueous solution of an aluminum compound or a transition metal compound to prepare a precursor suspension liquid; removing a salt by-produced in the above step; putting a base material into the precursor suspension liquid and conducting a hydrothermal reaction so that the titanium oxide composite coated with the inorganic silicate on the surface thereof is synthesized and its product is obtained. Thus the material for decomposing volatile organic compounds comprising the porous silicate-titanium oxide composite material can be provided. COPYRIGHT: (C)2010,JPO&INPIT
