Outline of Final Research Achievements

One-pot solvothermal syntheses of porous TiO2, ZrO2, and CeO2 nanoparticle assemblies with solid and hollow morphologies was established. Specific surface areas of the obtained ZrO2 and CeO2 were so high reaching 303 and 160 m2/g, respectively. Alkyl group modified SiO2-TiO2 composite porous assemblies were also synthesized according to the similar one-pot method. An Au@nano-voncave-comvex TiO2 assembly catalyst exhibited outstanding sintering resistance properties upon an exothermic CO oxidation reaction.
