Abstract: A method for the low-temperature heat treatment of toluene by using a composite material having a ternary NiO nanosheet @ bimetallic CeCuOx microsheet core-shell structure. The composite material having the ternary NiO nanosheet @ bimetallic CeCuOx microsheet core-shell structure is placed in an environment containing toluene, and is heated at a low temperature to complete the treatment of toluene.

The 3Ni/CeCuOx catalyst may completely catalyze toluene at 210° C., which has great research significance and certain application prospects for the actual solution of toluene polluted gas in the air environment.

Abstract: Provided are a ternary composite material having a NiO nanosheet/bimetallic CeCuOx microsheet core-shell structure, and a preparation method therefor, and an application thereof. CeCuOx has a large specific surface area and high stability.

The further growth of the NiO nanosheets having different concentrations effectively improves catalytic activity. A 3Ni/CeCuOx catalyst can realize complete catalysis of toluene at 210° C.
