▎ 摘　　要

NOVELTY - Method for preparing a metal framework-graphene oxide composite material, involves (i) mixing graphite oxide, ethanol and N,N-dimethylformamide under ultrasonic conditions to obtain a graphene oxide solution, (ii) mixing the graphene oxide solution with zirconium tetrachloride and a ligand, and carrying out solvothermal reaction. USE - The method is useful for preparing a metal framework-graphene oxide composite material used in removing sulfur-containing gas contaminants (claimed). ADVANTAGE - The method improves the porosity of the composite material, increases specific surface area, improves adsorption capacity of gas sulfur dioxide, carbonyl sulfide, hydrogen sulfide and carbon disulfide, and provides the composite material with an adsorption capacities of sulfur dioxide, carbonyl sulfide, hydrogen sulfide and carbon disulfide of 71.5-80.7 mg/g, 56.5-65.9 mg/g, 89.2-97.2 mg/g and 50.6-60.7 mg/g, respectively. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the composite material prepared by the method.
