제목 TiO2 광촉매를 이용한 TCE분해반응에서의 humidity의 영향
초록 The effect of humidity on the photocatalytic degradation reaction of trichloroethylene (TCE) in gas phase was investigated by using the pretreated TiO2 sol-gel films. It was observed that the photocatalytic activity of the TiO2 films depended more greatly on the pretreated conditions, for example, UV-preillumination than on the moisture content. When the relative humidity was over 50 %, the reaction rates decreased regardless of treatment condition of photocatalyst. The photocatalytic decomposition rate of TCE increased with the increase of light intensity. However, the influence of humidity on the reaction was not observed in the increased light intensity. The intermediates and byproducts of the reaction was not changed in different humidity conditions.
