Palladium-lead alloy nanowire, palladium-lead alloy nanowire catalyst and preparation method of palladium-lead alloy nanowire catalyst

The invention discloses a palladium-lead alloy nanowire, a palladium-lead alloy nanowire catalyst and a preparation method of the palladium-lead alloy nanowire catalyst. Ethanol is used as a reaction solvent, polyvinylpyrrolidone is used as a surfactant, hexadecyl trimethyl ammonium chloride is used as a coordination agent, tungsten hexacarbonyl is used as a reducing agent, and palladium acetylacetonate is used as a palladium source; the high-activity palladium-lead alloy nanowire rich in defects is prepared by taking palladium as a raw material and taking lead chloride as a lead source, and the palladium-lead alloy nanowire is subjected to structural characterization and performance testing. The high-efficiency electrocatalyst is efficiently prepared in a carbon-loaded mode for electrochemical performance testing. The palladium-lead alloy nanowire which is controllable in morphology, high in specific surface area and rich in active site is prepared through a simple, feasible, green and chemical optimized syn
