In order to disperse SnO2 nanoparticle on SiO2 substrate surface, reaction control of SnO2 precursor, consideration of interaction between the precursor and SiO2 surface, and formation of homogeneous reaction field on the SiO2 substrate were attempted. Starting from SnCl4 (aq) provides SnO2 single nanoparticles deposited on SiO2 through adsorption of Sn4+ on SiO2 surface during separation into SiO2 cake and un-reacted SnCl4 (aq) by filtration. SnCl4 (aq) remains in small spaces in SiO2 aggregates and can be passed fast by large spaces among the aggregates. While, dispersed SiO2 nanoparticles makes uniform cake where SnCl4 (aq) penetrates without residues. After calcinations of both composites, inhomogeneous SnO2 depositions covered over silica aggregates while fine SnO2 nanoparticle deposited on each silica surface. When NH3 (aq) added in SnCl4 (aq), fast growing of SnO2 through Sn(OH)4 occurs separately from silica surface due to little interaction between Sn(OH)4 and silica. A chelate solution of SnCl4 (aq) and acetylacetnate provided uniform SnO2 nanoparticle on silica surface even silica substrate aggregates. Because interaction between chelate and silica surface, steric hindrance derived from chelate ligand, could prevent from aggregation of the deposited SnO2 nanopaticle.
