A method for preparing and applying a carbon-supported platinum group metal-based high-entropy alloy.

Abstract

This invention discloses a method for preparing and applying a carbon-supported platinum group metal-based high-entropy alloy, relating to the field of high-entropy alloy synthesis technology. The method includes the following steps: S1: Taking several transition metal precursor salts and one platinum group metal salt in a certain proportion, and dissolving the transition metal precursor salt and the platinum group metal salt in a mixed solvent to obtain a dispersion; S2: Transferring the dispersion into a reaction vessel for reaction, and then washing it by ultrasonic centrifugation after the reaction; S3: Drying the washed raw material in a vacuum oven to obtain a carbon-supported platinum group metal-based high-entropy alloy. This invention uses transition metals such as copper, iron, nickel, lead, zinc, vanadium, cobalt, molybdenum, and bismuth, which promote reduction reactions, to impregnate palladium metal, and uses a solvothermal synthesis method to prepare the platinum group metal-based high-entropy alloy. This preparation process allows the amorphous carbon generated simultaneously during the reduction of the metal precursor to act as a carrier, controlling both the flower-like alloy morphology and the dispersibility of the alloy particles in solution.
