TiO_2镀膜次数对清除乙烯气体的影响

Influence of number of times for TiO_2 film coated on glass tube to decompose ethylene gas

用溶胶 凝胶方法,将TiO2薄膜浸渍涂膜在玻璃管上,通过自制的反应器对一定浓度的乙烯气体进行清除实验,利用气相色谱检测乙烯气体浓度的变化,并利用UV vis,AFM对管载TiO2薄膜进行表征。实验结果表明,TiO2三次镀膜对乙烯具有良好的清除作用。

In This paper reports the study on the influence of number of times for thin TiO_2 films coated on glass tubes to decompose ethylene gas, by using sol-gel method. The experiment were performed in the home-made reactor, detecting the gas concentration via gas chromatogram and characterizing the film by UV-vis,AFM. It reveals that three times coating is effective.
