| Abstract: | Catalytic oxidation technology can effectively treat waste gas containing volatile organic compounds（VOCs）. The research progresses on bimetallic catalysts for VOCs removal are summarized,especially the Ag,Au and Cu based bimetallic catalysts. The relationship between the catalytic activity for catalytic oxidation of VOCs and the structure of the catalyst is discussed from the aspects of preparation method,particle dispersion degree,morphology,loading capacity,carrier structure and surface modification,etc. It is pointed out that regulation for preparation of bimetallic catalysts can effectively improve the dispersion of metal active particles on the surface of carrier,thereby enhancing the bimetallic synergism and finally improving the catalytic activity to VOCs. |
