The application relates to the technical field of all-solid-state battery negative electrode materials, in particular to a high-entropy alloy negative electrode material and a preparation method and application thereof. The application provides a high-entropy alloy negative electrode material which comprises base elements and additive elements; the base elements comprise P and Ge, and a solid solution is formed between the P and the Ge; the additive elements comprise Zn and Al, and further comprise two or more than two of Si, Sn, Sb and Cu. The high-entropy alloy negative electrode material has high specific capacity, rate performance and long cycle stability.

The application discloses a Pd-Cu-M / alpha-Si3N4 supported metal catalyst and a preparation and application thereof. The preparation method comprises the following steps: step 1): dissolving palladium acetylacetone, copper acetylacetone and acetylacetone salt of metal M in a solvent to prepare a precursor solution, adding an alpha-Si3N4 carrier, and fully stirring to obtain a suspension; the metal M is a rare earth metal element; step 2): transferring the suspension obtained in step 1) into a polytetrafluoroethylene-lined steel autoclave, sealing in an induction heating electric furnace for heating, and cooling to room temperature; step 3): centrifuging the suspension cooled in step 2) to collect the solid, washing and drying the solid, and obtaining the Pd-Cu-M / alpha-Si3N4 supported metal catalyst after the drying is completed. The application provides the application of the catalyst in a low-temperature hydrogen catalytic oxidation reaction, and the catalyst has high hydrogen conversion rate and excellent stability.
