description The invention discloses a waste SF6 efficient thermal degradation method based on bi-metal concerted catalysis, and belongs to the technical field of treatment of atmospheric pollutants. The process comprises the following steps: (1) carrying out thermocatalytic degradation on SF6 and SF6, mixing reducing gas with inert gas, carrying out thermocatalytic degradation on the obtained mixed gas under the action of a bimetallic synergistic catalyst, and collecting degraded waste gas; the bimetallic synergistic catalyst is composed of nanoscale copper oxide and zinc oxide particles and a carbon skeleton film formed by a ZIF-8 metal organic skeleton, wherein the copper oxide and zinc oxide particles are wrapped by the carbon skeleton film; and (2) waste gas treatment: carrying out alkali washing and drying on the degraded waste gas to complete recovery. The method has the advantages of high efficiency, environmental protection and economy, can be widely applied to the degradation of the SF6 waste gas and the recover
