| 中文摘要 |
| 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,提出了无水条件下TCE的光催化降解机理为空穴直接氧化机理. |
| 英文摘要 |
| 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,CO2 and Cl2.The equation of photocatalytic degradation agreed with Langmuir-Hinshelwood rate form.Reaction schemes of TCE were proposed as valence band hole direct oxidation. |
