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. A NiO/CeCuOx core-shell structured composite material catalyst is prepared by growing NiO nanosheets on the surface of CeCuOx by low-temperature hydrothermal treatment and heat treatment. The bimetallic CeCuOx microsheet shows better catalytic performance for toluene than monometallic oxides, i.e., copper oxide and cerium oxide. 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.
