Abstract

The invention relates to a method for synthesizing an amorphous nickel-cobalt alloy nano-film loaded with platinum particles, which comprises the following steps: taking an artificial active pyroxylin membrane as a template; reducing a metal salt by a composite hydrogen compound at the normal temperature; and then obtaining the amorphous nickel-cobalt alloy nano-film loaded with the platinum particles. The method has very high regulation to an alloy component content of a product; a simple inorganic salt is adopted as a reactant respectively with very strong universality; the product preparedby the method has good electrochemical property, can be used as a high performance electrochemical catalyst and has wide development prospect and application space; and the method has the advantages of simple process, mild preparation conditions, stable appearance and high purity of the product, convenient and concise treatment of the product, and suitability for middle-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a method for synthesizing an amorphous nickel-cobalt alloy nano film loaded with platinum particles by an artificial active template. Background technique [0002] Nano science and technology is a new technology that is developing rapidly in the late 1980s. The so-called nanotechnology refers to the science and technology of manufacturing materials or micro-devices with units composed of several molecules or atoms—nanoparticles. Nanoparticles refer to fine particles of metals or semiconductors with a size ranging from 1 to 100 nm. The special structural level of nanoparticles endows it with many special properties and functions, such as surface effect, small size effect, quantum size effect, macroscopic quantum tunneling effect, dielectric confinement effect, etc. This series of novel physical and chemical It has great application value in many fields, especially ...
