Abstract

The invention provides a preparation method of a palladium-tin-gallium ternary alloy nano material, which comprises the following steps: A) under the protection of inert gas, mixing a metal palladium precursor, a metal tin precursor, a metal gallium precursor, methylamine hydrochloride, trioctylphosphine and oleylamine, and heating for reaction to obtain a primary reaction solution; and B) further heating the reaction liquid for reaction, and washing and drying to obtain the palladium-tin-gallium ternary alloy nano material. The preparation method provided by the invention is simple and convenient to operate and controllable in reaction condition, and the obtained nano material is spherical, uniform in size and good in dispersity. By regulating and controlling the feeding ratio of each metal precursor, the components of the nano material can be precisely regulated and controlled. A carbon-loaded nano-material catalyst prepared by loading the nano-material on a carbon carrier shows excellent catalytic activity and stability on electrocatalytic oxidation reactions of various alcohols, and has important application prospects in the technical field of new energy sources such as direct alcohol fuel cells and the like.
