Description

Fe-Co-Mo-P-C amorphous alloy electrocatalyst and preparation method and application thereof
Technical Field
The invention relates to an electro-catalysis application of an amorphous alloy strip, in particular to a Fe-Co-Mo-P-C amorphous alloy electro-catalyst, a preparation method and an application thereof
Background
With the increasing energy crisis and environmental pollution, the development of various new energy sources and renewable energy sources has been highly regarded by various countries in the world, and hydrogen is regarded as the most ideal energy carrier due to its advantages of cleanness, no pollution, high efficiency, storage and transportation, etc. Among the current hydrogen production technologies, hydrogen production by water electrolysis has great value for solving energy crisis and environmental problems in the future. Catalysis plays a crucial role in the design of efficient processes and systems, maximizing the value of the feedstock, while reducing waste production and energy requirements.
In the early stage of hydrogen evolution electrocatalyst research, noble metal materials such as Pt and Pd were the main focus of attention. Precious metal materials have limited themselves to widespread commercial use due to high cost and scarcity. With the development of research in recent years, in order to avoid high use costs, researches on electrocatalysis of hydrogen evolution reactions of transition metal alloys and nitrides, borides, carbides, sulfides and phosphides thereof have been receiving wide attention. A series of transition metal compounds were prepared and exhibited excellent electrocatalytic properties. Since then, the related materials have been the hot spots for the research of electrocatalytic materials.
Amorphous materials, such as metallic glasses (also known as glass metals or alloys), are considered as potential electrocatalysts due to their good stability in corrosive media and high catalytic activity. And a large number of experiments prove that the iron-based nano material meets low cost benefit and has good corrosion resistance and electrocatalytic activity. Unlike materials synthesized by general wet chemical methods, metallic glasses are generally produced on a large scale by melt spinning, enabling wide commercial applications. In view of the excellent properties of metallic glasses, including excellent mechanical properties, low production cost and good corrosion resistance, it is now urgently needed to design a catalyst based on transition metal Fe-based amorphous alloys to achieve high hydrogen evolution electrocatalytic activity. Experimental results show that the amorphous alloy material is a good electrocatalyst, and has high electrocatalytic activity and long-term stability in an acidic solution. Based on the excellent mechanical property and low production cost, the Fe-Co-Mo-P-C may represent a novel electrocatalyst material at present, and has great commercial application prospect.
