| abstract |
The invention provides a halogen-containing VOCs catalytic combustion catalyst and a preparation method thereof, belonging to the field of catalysis and environmental protection. The catalyst is a quaternary metal composite oxide, and its structural form is C x Zr y M 1-x-y O 2 , M is Fe, Co, Cu, Mn, Ni, Zn or Mg; x is 0.2-0.8, y is 0.8-0.2. The catalyst is prepared by homogeneous precipitation of metal precursor salts according to a certain proportion. The catalyst of the invention has high halogen-containing VOCs catalytic combustion activity and stability, and the performance is close to or better than that of the precious metal catalyst loaded with ruthenium. |
