摘要
以介孔氧化钛为钛源,草酸为碳源,在N2气氛中500℃时进行固相热解,制备介孔碳-氧化钛(C/TiO2)纳米材料,采用溶胶-凝胶方法在C/TiO2上负载Pt纳米颗粒,制成了P/tC/TiO2纳米复合材料,并且在导电玻璃(ITO)上涂膜,制备C/TiO2和P/tC/TiO2电极;用X射线衍射对C/TiO2和P/tC/TiO2的结构进行表征,测定电极的光电化学性能。结果表明:C/TiO2和P/tC/TiO2呈现锐钛晶型,薄膜在0.1mo/lLNa2SO4溶液中具有典型的光电化学活性,P/tC/TiO2和C/TiO2比溶胶-凝胶法制备的TiO2薄膜具有更强的光激发和更稳定的光电流响应性能。
Mesoporous TiO2 being titanium source,oxalic acid being carbon source,500-hour solid antipyretic in N2 environment,mesoporous C/TiO2 Nano-composite is prepared.First,sol-gel method is used to load Pt Nanometer by C/TiO2和Pt/ C/TiO2 to produce Pt/ C/TiO2 Nano-composite and C/TiO2 and Pt/ C/TiO2 electrodes by coating ITO.Second,C/TiO2 and Pt/C/TiO2 structure is characterized by x-ray diffraction to determine photo-electrochemical characteristics of the electrode.The findings show that C/TiO2 and Pt/C/TiO2 render anatase crystal,that the thin film has typical electrochemical activity in solution of 0.1mol/LNa2SO4 and that Pt/C/TiO2 and C/TiO2 have more intense optical excitation and more stability in photo-electrochemical properties than TiO2 thin film prepared by sol-gel method.
