Preparation method and application of supported noble metal catalyst based on Mxene

The invention relates to a preparation method and application of a supported noble metal catalyst based on Mxene, and belongs to the technical field of preparation and application of supported noble metal catalysts. After an aluminum layer is etched by a layered ternary metal titanium-carbon-aluminum material, intercalation is performed to obtain an MD carrier or the MD carrier is further treated to obtain a TTS composite carrier, and Pd nanoparticles are loaded to be applied to a p-CNB hydrogenation reduction reaction. The prepared catalyst has a special accordion structure, more active sites can be provided for catalytic reaction, Pd nano particles are stabilized and the electronic state of the Pd surface is modulated through interaction between the precious metal and the carrier, so that the catalyst has the advantages of high activity, high selectivity and high stability, and has a wide application prospect. 本发明是一种基于Mxene的负载型贵金属催化剂制备方法及应用，属于负载型贵金属催化剂的制备与应用技术领域。层状三元金属钛碳铝材料刻蚀铝层后插层获得MD载体或对MD载体进一步处理获得TTS复合载体，
