The invention particularly relates to a preparation method and application of a special catalyst for non-methane total hydrocarbon analysis based on MXene, belonging to the technical field of catalytic environmental protection and comprising the following steps: obtaining MAX phase materials and transition metal salts; mixing MAX phase materials and transition metal salts, grinding and carrying out first roasting to obtain a prefabricated compound; adding acid into the prefabricated compound, stirring, and performing first drying to obtain a dried compound; obtaining a Pd precursor solution; and mixing the Pd precursor solution with the dry compound, and sequentially carrying out impregnation, secondary drying and secondary roasting to obtain the MXene-based special catalyst for non-methane total hydrocarbon analysis. The MXene-based catalyst special for analyzing the non-methane total hydrocarbons, prepared by the steps, has excellent catalytic activity, the efficiency of removing the non-methane total hydrocarbons reaches more than 98%, and the methane retention rate also reaches more than 98%. |
