Abstract

The invention discloses an amorphous alloy material. The chemical formula of the amorphous alloy material is AlxNiyCozMnaYbAuc, wherein x ranges from 75 to 99.9, y ranges from 0 to 10, z ranges from 0to 5, a ranges from 0 to 4, b ranges from 0 to 10, c ranges from 0 to 5, and the sum of x, y, z, a, b and c is 1. The invention further discloses a preparation method of the amorphous alloy materialand application of the amorphous alloy material as a water electrolysis hydrogen evolution catalyst. The amorphous alloy material serves as a substrate-free self-supporting catalyst, high-performancehydrogen evolution catalytic activity is provided through cooperativity of multiple elements, and heat energy wasted by water decomposition is effectively reduced; and meanwhile, the catalyst has highmechanical strength, the material can be effectively supported to work for a long time, and the problem that the working time of a traditional catalyst is shortened due to the fact that an adhesive is prone to falling off is solved.

Description

technical field [0001] The present application relates to an amorphous alloy material, its preparation method and application, more specifically, relates to the preparation of electrolytic water catalyst, especially the preparation method of electrolytic water hydrogen evolution catalyst, and belongs to the field of chemistry. Background technique [0002] With the tremendous development of industrial society, the increasing use of fossil fuels has led to the emission of a large amount of greenhouse gases, which has brought serious environmental pollution problems. Hydrogen energy has attracted widespread attention due to its high energy density, high combustion calorific value and zero environmental pollution, and is regarded as an ideal clean energy in the future. Effectively realizing the conversion of renewable energy to hydrogen production is the current research difficulty. Among the existing hydrogen production methods, hydrogen production by electrolysis of water is...
