▎ 摘　　要

NOVELTY - Preparing modified graphene roll involves mixing MXene materials, graphene and water to obtain MXene-graphene mixed solution, where ratio of the mass sum of the MXene materials and the graphene and volume of the water is (0.1-1 mg):1 mL. The MXene-graphene mixed solution is sequentially heated, cooled by using liquid nitrogen and performed freeze-drying to obtain an MXene-graphene roll. The metal particles are loaded on the surface of the MXene-graphene roll. USE - Method for preparing modified graphene roll used in catalytic redox reaction (claimed). ADVANTAGE - The method enables to prepare modified graphene roll which has good conductivity, and good catalytic performance and stability.
