| Abstract: | The photocatalytic nanocomposites in this study were prepared by sol-gel method combined with temperature-programmed hydrothermal treatment and template method： nano-composite materials H6P2W18O62/TiO2（P123）和H3PW12O40/TiO2（P123） and H3PW12OWTiO2（P123）. The phase structures, chemical composition, optical absorption properties and surface physicochemical properties were characterized via F＇FIR spectroscopy, X-ray diffraction （XRD）, inductively coupled plasma atomic emission spectroscopy（ICP-AES）, nitrogen adsorption/desorption. The results showed that thebasic structure of polyoxometaltes in the composites has been basicly matained. The composites H6P2W1806gTiO2 （P123）by the non-ionic surfactant P123 used in the synthesis are periodical mesoporous materials with surface area of 414.6 m2 g-1. |
