摘要
研究无水条件下气相三氯乙烯(TCE)的光催化降解反应及其机理,结果表明三氯乙烯的降解产物为HCl、CO2及Cl2,光催化降解速率方程符合Langmuir-Hinshelwood公式。
The photocatalytic degradation of trichloroethylene(TCE) in the gas phase without water using anatase titanium dioxide powder as catalyst was studied.It was proved that the products were HCl,CO 2 and Cl 2.The equation of photocatalytic degradation agreed with Langmuir Hinshelwood rate form.Reaction schemes of TCE were proposed as valence band hole direct oxidation.
