含钴氧化物催化剂去除VOCs性能研究进展OA

Catalytic oxidation is one of the important methods for eliminating volatile organic compounds(VOCs).Cobalt-based catalysts have become a research hotspot due to their low cost and excellent activity.The research progress of cobalt oxide catalysts and cobalt-containing composite metal oxides in the removal of VOCs was systematically summarized,and it was pointed out that the performance of the catalyst is related to its morphology,surface structure,crystal phase structure,and the synergistic effect between components.The concentration of surface active oxygen and the redox properties of the species are the main factors affecting the catalytic performance.The controllable preparation can be achieved by optimizing the methods and conditions of catalyst preparation.
