| 摘 要： | 以草酸氧钛、柠檬酸、乙酸锌为原料，水为溶剂，采用溶胶－凝胶法制备纳米级钛酸锌粉体，用FT－IR、XRD、TEM等方法对其形成条件、组成、结构和形貌进行了表征。结果表明，不同的灼烧温度对产物的组成和 晶型有较大影响。以ZnTiO3为催化剂对水溶性染料光催化降解有较好的活性，无污染，且重复利用率高。

| Abstract: | The nano size ZnTiO 3 powder has been prepared by a sol gel method from titanium oxyoxalate,citric acid,zinc acetate and characterized by FT IR,XRD and TEM.The effectiveness of photocatalytic degradation and influence of irradiation time for dyestuff in ultraviolet light have been measured.The results show that the crystal patterns are influenced by temperature,and the catalytic activity of ZnTiO 3 is satisfactory. |
