Halogenated metal perovskites

The halogenated volatile organic compounds have an important role in air pollution, since they are active in ozone depletion of stratosphere [50]. The oxidation of these molecules generated HCl, and in consequence the catalyst should be stable under reaction conditions, and limit the formation of hazardous volatile organic (phosgene, chlorinated dioxins, or dibenzofurans) and inorganic (metal chlorides or oxychlorides) compounds [51]. The structure of the perovskite fi amework induces such stabilization, at least compared to noble metal catalysts, and, in addition, decreases the reactivity of the produced chlorine or hydrochloric acid ... 

Studies reported to date confirmed the successful replacement of noble metals by perovskites in total oxidation of heavy hydrocarbons and aromatics. Besides activity, these materials allow a good stability, especially in the presence of halogens. Another relevant advantage is the very large composition of these...
