“…Under most circumstances, by controlling the selectivity of the catalyst, high eco-friendliness is achieved under the most favorable conditions. [10,11] According to the active components in the catalyst, during catalytic combustion, the catalysts can be classified into precious metal catalysts and transition metal oxide catalysts. [12] Precious metal catalysts are scarce and expensive, and they tend to produce chlorine-containing organic by-products in catalytic reactions.…”

For the catalytic combustion reaction of chlorinated volatile organic compounds (CVOCs), the redox properties and acid sites of the catalyst surface are key factors in determining the activity, selectivity, and chlorine‐resistance stability. Herein, a series of SnMnOx catalysts for the catalytic combustion of CVOCs were prepared by the changing of Sn‐doping way to regulate the electron valance state of Mn element, including reflux (R‐SnMnOx), co‐precipitation (C‐SnMnOx) and impregnation (I‐SnMnOx). It was discovered that the R‐SnMnOx catalyst had better activity and chlorine resistance than the R‐MnOx, C‐SnMnOx and I‐SnMnOx catalyst, and we discovered that the doping ways of Sn in MnOx catalyst could regulate greatly the surface acidity, active oxygen species, the chemical state of Mnn+ species, and redox ability. Especially, the R‐SnMnOx catalysts exhibit excellent water resistance, and the reasons were related to the strong interaction of Snn+ and Mnn+, which could promote obviously the dispersion of active Mn species, form a large number of acid sites, provide the abundant lattice oxygen species, and own the excellent redox ability, which accelerate the rate of charge transfer between Snn+ and Mnn+ (Sn4++Mn2+→Sn2++Mn4+) to produce the abundant active species and accelerate the rapid conversion of benzene and intermediates conversion.

A three-dimensional hollow CoFe oxide prism catalyst was successfully prepared via a self-template strategy. This bimetallic oxide catalyst demonstrated excellent catalytic activity in cross-dehydrogenative coupling reactions of 1,2,3,4tetrahydroisoquinolines under mild conditions compared to its monometallic oxide counterparts. A preliminary mechanistic investigation showed the involvement of reactive oxygen species, produced from molecular O 2 by the active bimetallic oxide catalyst in the catalytic cycle.
