摘要
通过改进溶胶-凝胶工艺,在低温条件下制得了具有一定光催化性能的TiO2超微薄膜,并通过甲基橙溶液的光催化降解试验表明:随着TiO2浓度的增加光催化效率提高;当浓度增加到一定量时,光解率不再提高。
By improving the sol -gel processing technique in low temperature, we get the TiO2 supermiero with certain photochemical catalysis. With the experiments of degradation for Methyl orange solution, the essay shows that： the efficiency of photochemical catalysis improves with concentration of TiO2 ; and the etticiency win be constant even the concentration increases.
