COBALT-MANGANESE COMPOSITE OXIDE CATALYST, PREPARATION METHOD THEREFOR, AND METHOD FOR COUPLING COBALT-MANGANESE COMPOSITE OXIDE CATALYST WITH PLASMA TO PURIFY ORGANIC WASTE GAS

摘要

A cobalt-manganese composite oxide catalyst, a preparation method therefor, and a use thereof in the purification of organic waste gas. The catalyst comprises a carrier and a catalytically active component. The carrier is anatase TiO₂ having a photocatalytic property. The catalytically active component is a double metal oxide comprising manganese oxide and cobalt oxide. In the catalytically active component, the mass content of manganese and cobalt is 5-15% of the total mass of the catalyst. In the catalytically active component, the molar ratio of manganese to cobalt is 1:5-5:1.
