【正文】 o improve the life of the same time, the UV light absorbed could be downconverted to visible light, which can be absorbed by dye molecules to generate photo this means, the energy loss due to the absorbed UV light is pensated and the overall conversion efficiency was even improved by % of the solar cells without fluorescent active gold catalysts have been designed via monodispersed gold colloids on LaVO4 nanocrystals with controlled size as more welldefined size of the gold particles is a very important parameter to get active novel colloidal deposition method to prepare Au/LaVO4 nanoposite catalyst with monodispersed Au colloids and uniform LaVO4 nanoplates in nonpolar Au colloids with tunable size(such as 2, 5,7, 11, 13, and 16 nm)and LaVO4 nanocrystals with welldefined shapes were presynthesized assisted with oleic acid/ the following immobilization process, the particle size and shape of Au and LaVO4 were nearly Au/LaVO4 nanoposite showed high catalytic activity for CO oxidation at room sizes of gold particles were welldefined before the immobilization process, size effect of gold particles was easy to be investigated and the results show that 5nmAu/LaVO4 nanoposite has the highest activity for CO synthetic method can be extended further for the preparation of other posite vanadate micro/nanocrystals with different morphologies were synthesized by surfactant assisted hydrothermal/solvothermal studies on the crystal growth reveal the relationship between the crystal structures and the dimensional potassium niobate nanostructures with different positions were achieved by simply controlling pH value of the hydrothermal was found that the solvent plays an important role in the phase control of the KNbO3 on the catalysis properties of iron oxide nanocrystals with different size and morphology showed that the catalytical activities were influenced not only by the size and BET of the materials, but also by the crystal planes due to the facts that t different active sites on certain reactions, varies with crystal TiO2 nanocrystals with hydrophobic surface were prepared by controlled solvothermalreactions，followedbyanewlydeveloped microemulsionbased method to assemble the nanocrystals to colloidal spheres with hydrophilic spheres, which are expected to show excellent properties in applications such as catalysis, could then be achieved by annealing of colloidal words:Hydrothermal/solvothermal synthesis。Functional metal oxides。Nanostructures
