摘　　要：采用微波辐射法由溶胶制备出TiO2薄膜,用XRD和TEM对催化剂进行了表征。以甲基橙为模拟污染物,考察了微波功率和膜层厚度对TiO2光催化活性的影响,并实际考察了TiO2薄膜对啤酒废水的降解效果。结果表明:制备的TiO2薄膜具有较高光催化活性,微波功率300 W时光催化活性最大,对啤酒废水具有良好的处理效果。TiO2 thin films were prepared from a TiO2 sol by microwave heating, and characterized by XRD and TEM. Effect of microwave power and film thickness on photoeatalytic activity of TiO2 was investigated with methyl orange as degradation agent. Results indicated that TiO2 film has high photocatalytic activity, and the photocatalytic activity is the largest when microwave power is 300 W, which has effective treatment of brewery wastewater.
