Method for low-temperature heat treatment of toluene by using composite material having ternary NiO nanosheet @ bimetallic CeCuOx microsheet core-shell structure

A method for a low-temperature heat treatment of toluene by using a ternary NiO nanosheet @ bimetallic CeCuOX microsheet core-shell structure composite material, comprising the following steps:

• (1) mixing a cerium salt, a copper salt, an organic acid, and a solvent, performing a solvothermal reaction, and calcining a reaction product of the solvothermal reaction to obtain a CeCuOX microsheet;
• (2) performing a water bath reaction of a mixture of a nickel salt, urea, and the CeCuOx microsheet in an alcohol/water mixed solvent, and calcining a reaction product of the water bath reaction to obtain the ternary NiO nanosheet @ bimetallic CeCuOx microsheet core-shell structure composite material;
• and
• (3) placing the ternary NiO nanosheet @ bimetallic CeCuOx microsheet core-shell structure composite material into a toluene-containing environment, heating at a low temperature, and completing the low-temperature heat treatment of toluene,
• wherein a molar ratio of the cerium salt, the copper salt and the organic acid in step (1) is 2:(1.0-1.1):(4.0-4.1);
• the solvent is dimethylformamide (DMF);
• and the organic acid is terephthalic acid;
• and
• wherein the low-temperature heat treatment is conducted 200-220° C.
