The invention provides a preparation method and application of a novel carbon-based material noble metal catalyst. The method comprises the following steps: modifying a catalyst carrier carbon-based new material, preparing a to-be-loaded solution, impregnating, spraying or blending the modified carbon-based carrier to prepare a semi-finished product of a target catalyst, and reducing the semi-finished product of the target catalyst to make the catalyst have catalytic activity. Compared with a catalyst prepared from a traditional carrier, the novel carbon-based material has more advantages; thesupported noble metal can be recycled through combustion of the carbon-based carrier, the method is simple and convenient, the surface activity, stability, corrosion resistance and wear resistance are higher, by adjusting the preparation process and surface modification treatment, the catalyst can adapt to more complex working environments, the catalytic performance of the catalyst can be furtherimproved, and the applica
