【摘要】 报道了用sol gel方法在玻璃管上制备二氧化钛薄膜对清除乙烯气体的光催化实验,研究了二氧化钛一次镀膜对乙烯浓度随催化反应时间的变化关系。结果发现,二氧化钛镀膜有较好的清除乙烯的效果,当反应进行到46h时乙烯气体的色谱峰完全消失,即乙烯气体已经被完全清除掉,对相同处理条件下的二氧化钛粉体做XRD分析知该条件下的二氧化钛为锐钛矿晶型。更多还原

【Abstract】 TiO₂ thin film was prepared by sol-gel method on glass pipe and the C₂H₄ gas photocatalysis reactions were studied. The relation between concentration of C₂H₄ gas and the reaction time was reported here by using one time coating of TiO₂ thin film on the glass pipe as photocatalyst. The results show that the TiO₂ film favorites the degradation of C₂H₄, and the peak of C₂H₄ disappeared after the reaction for 46?h, that is to say, C₂H₄ has been cleared out and XRD method was used to characterize the powder under the same situation, the result indicates that the crystal phases of TiO₂ is anatase. 更多还原
