| 摘 要： | 为了提高TiO2薄膜光催化剂的活性,通过在氟钛酸铵、硼酸混合溶液中加入硝酸银,应用液相沉积法(LPD)制备了掺银TiO2薄膜.采用XRD、SEM、XPS、UV-vis等手段对其组成、表面形貌和结构进行了测试表征;并以甲基橙为模型物,进行降解实验评价Ag-TiO2薄膜的光催化性能.实验结果表明:硼酸/氟钛酸铵摩尔比为2～4,热处理温度为400℃,硝酸银掺杂量为0.03 mol/L时,Ag-TiO2薄膜具有良好的锐钛矿相晶型,同时具有较高的光催化性能.

| Abstract: | In order to improve the photocatalytic activity of TiO2 thin films,Ag-doped TiO2 films were synthesized by liquid phase deposition method and characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),X-ray photoelectron spectroscopy(XPS) and UV-vis spectroscopy.Methyl orange was used as the reactant to evaluate the photocatalytic activity of catalyst samples.The experimental results indicate that the photocatalytic activity of Ag-doped TiO2 films which show anatase is higher than that of TiO2 films when the molar ratio of H3BO3/(NH4)2TiF6 is 2～4,the silver nitrate concentration is 0.03 mol/L and the heating temperature is 400 ℃. |
