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

Abstract

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.
