摘要

提出了一种促进CVOCs在低温下消除的新策略，特别是在O2下进行加氢脱氯。在225°C条件下，1000 ppm H2的加入使氯乙烯氧化的循环频率和HCl产率分别提高了22倍和43倍以上。用一个新的化学方程（CH2 + CHCl + H2 + O2→CO2 + HCl + H2O）来描述该反应。

Hydrodechlorination under O2 promotes catalytic oxidation of CVOCs over a Pt/TiO2 catalyst at low temperature†

A novel strategy to promote elimination of CVOCs at low temperature, specifically involving hydrodechlorination under O₂, was proposed. Turnover frequency and HCl yield in oxidation of vinyl chloride increased, respectively, by over 22 and 43 times (225 °C) with the assistance of 1000 ppm H₂. A new chemical equation (CH₂CHCl + H₂ + O₂ → CO₂ + HCl + H₂O) was used to describe the reaction.
