PROBLEM TO BE SOLVED: To provide a method of producing oxide particulates with nanoparticles fixed therein and the oxide particulates. SOLUTION: A method of producing nanoparticle-fixed particulates includes a process in which nanoparticles are integrated into droplets or gel capsules and a process in which a nanoparticles integrated bodys, as a precursor or growth nuclei, on the surfaces of them, colloid produced by hydrolyzing an alkoxide is deposited, agglomerated and subjected to, dehydration polycondensation. In this method, the alkoxide is one or a mixture of at least two selected from the group of titanium tetramethoxide, titanium tetraethoxide, titanium tetraisopropoxixde, titanium tetrabutoxide, tetramethoxy silane, tetraethoxy silane (TEOS), tetrapropoxy silane, tetrabutoxy silane, and phenyl triethoxy silane (PTES). The oxide particulates with nanoparticles fixed are obtained by the method. COPYRIGHT: (C)2004,JPO
