Abstract

Abstract:

The fixation technology of nanometer-sized oxides with photocatalysic activity is reviewed, as well as the influences of different supporters on photocatalysic activity.Researches on this task by coating ion modified nanometer-sized ZnO on glass-substrates/aluminum foil, SnO₂-ZnO composite sol-gel on glass-substrates/aluminum foil, and nanometer-sized TiO₂ composite electrodeposition on metals are introduced.The photocatalytic activities of nanometer-sized oxides thin films are studied.These thin films have been applied to photocatalytic degradation of methyl orange as model of organic pollutant.Moreover, sol-gel and composite electrodeposition are regarded as two promisingmethods.

Key words: nanometer-sized oxides, fixation, photocatalysis

摘要：

综述了具有光催化活性的纳米氧化物固载化的各种技术及不同载体对其光催化活性的影响,介绍了课题组在该方面所作的一些研究工作:采用离子掺杂纳米ZnO后在玻璃片/铝箔上涂膜、SnO₂修饰的纳米ZnO的复合溶胶在玻璃片/铝箔上镀膜、在金属表面采用纳米TiO₂复合电镀成膜等不同的方法,实现了纳米氧化物复合膜光催化剂的固载化,并以甲基橙水溶液模拟有机污染物,研究了不同的纳米氧化物复合膜的光催化降解性能。认为溶胶法制备复合膜及复合电镀成膜应是很有发展前途的两种方法。
