▎ 摘  要

NOVELTY - Method for preparing high-entropy alloy nanoparticles involves (a) taking platinum, palladium, ruthenium, rhodium, iridium, iron, cobalt, nickel, copper, zinc, cadmium, aluminum, chromium, tin, indium, gallium, germanium, gold, molybdenum, lead, bismuth, vanadium and/or manganese, dissolving or dispersing metal organic salt in a certain volume of chloroform, acetone, water, ethanol and other solvents to obtain solution (A), dispersing the carrier or the carrier and the organic ligand in a certain volume of solvents such as chloroform, acetone or water to obtain dispersion (B), (b) mixing solution (A) and dispersion (B) and ultrasonically dispersing to obtain solution (C), volatilizing the solvent in the solution (C) to obtain the precursor (D), placing the precursor (D) in a tube furnace, heating to the required reduction temperature, and thermally decomposing the organic ligands to expose isolated metal atoms, and multi-component metal atoms aggregate to form the product. USE - The method is used for preparing high-entropy alloy nanoparticles which is used in thermal catalytic selective hydrogenation and anode catalysis of acidic electrolytic water (all claimed). ADVANTAGE - The method is simple and easy to implement, and adopts simple equipment. DETAILED DESCRIPTION - Method for preparing high-entropy alloy nanoparticles involves (a) taking 2 or more of platinum, palladium, ruthenium, rhodium, iridium, iron, cobalt, nickel, copper, zinc, cadmium, aluminum, chromium, tin, indium, gallium, germanium, gold, molybdenum, lead, bismuth, vanadium and manganese, dissolving or dispersing metal organic salt in a certain volume of chloroform, acetone, water, ethanol and other solvents to obtain solution (A), dispersing the carrier or the carrier and the organic ligand in a certain volume of solvents such as chloroform, acetone or water to obtain dispersion (B), (b) mixing solution (A) and dispersion (B) and ultrasonically dispersing to obtain solution (c), volatilizing the solvent in the solution (c) to obtain the precursor (D) in a vacuum or gas atmosphere, placing the precursor (D) in a tube furnace, heating to the required reduction temperature, and thermally decomposing the organic ligands to expose isolated metal atoms, and multi-component metal atoms aggregate to form the product, according to the characteristics of the selected carrier, etching the obtained supported high-entropy alloy nanoparticles to remove the carrier to obtain pure high-entropy alloy nanoparticles for coating or other purposes.
