摘要：

Herein, a Mn cations highly dispersed and bimetallic interfacial interaction strengthen catalyst, MnCoOx, via combinations of MOF-templated method, Mn cation doping has been constructed for the chlorobenzene (CB) oxidation. As a result, MnCoOx-M possessed the best chlorobenzene degradation capacity and stability than those of similar bimetallic compounds prepared by co -precipitation method and single-phase oxide. Notably, this superior catalyst obtained a high mineralization efficiency with inhibition effect of the CO generation. The excellent performance of MnCoOx-M can be conducted to the good dispersion of the metal cations as well as a stronger Mn-Co interaction, which are further induced the excellent redox properties of the catalyst. Besides, the humidity tolerance experiments showed that a certain H2O participation can significantly inhibit the generation of some types of organic by-products, especially chlorinated organic compounds. Mechanistic studies showed that chlorobenzene dissociated on the surface of MnCoOx-M to form benzoquinone, phenolates, maleates, etc., which were finally oxidized to inorganic products.
