Description

Preparation method and application of carbon fiber loaded nano cobalt-molybdenum alloy catalyst
Technical Field
The invention belongs to the field of inorganic functional materials, relates to a preparation technology of an electrolytic water catalytic material, and particularly relates to a preparation method of a carbon fiber loaded nano cobalt-molybdenum alloy material and application of the carbon fiber loaded nano cobalt-molybdenum alloy material in the aspect of efficient electrocatalytic splitting of water to produce hydrogen.
Background
The continuous increase in global energy demand, the accelerated consumption of traditional coal, petroleum and fossil fuels, and the consequent environmental pollution problems, has raised a strong interest in developing alternative energy sources. Particularly, the aggravation of geopolitical anxiety and climate threats arouses the development of people towards the direction of having a renewable, stable and environment-friendly benign energy source. Because of the advantages of zero emission of combustion, high energy density and the like, hydrogen energy is considered as one of ideal green energy sources capable of replacing the traditional fossil fuel. Hydrogen production by electrolysis of water is an efficient method for producing hydrogen fuel, but requires high performance water electrolysis catalysts to accelerate the Hydrogen Evolution Reaction (HER) and reduce power consumption. Currently, platinum-based materials are considered the most efficient electrocatalysts, but their high cost and non-renewable nature limit their widespread use. Therefore, there is an urgent need to develop a low-cost, efficient and stable platinum-based alternative electrocatalyst.
In principle, if a catalyst has excellent hydrogen evolution catalytic activity, it may come from one or more of the following four aspects: (1) a large number of active centers are present in the catalyst; (2) the reaction intermediate has proper binding capacity with an active site, so that the catalyst has good intrinsic activity; (3) between the catalyst surface and the electrolyte, the reactant (H)+/H2O) and product (H)2/OH-) A rapid mass transfer reaction occurs; (4) the electrode made of the catalyst has excellent conductivity. Over the past few decades, many transition metal-based catalysts have been considered as desirable alternatives to noble metal hydrogen evolution catalysts, including transition metal-based alloys, compounds (e.g., oxides, hydroxides, sulfides, carbides, selenides, and phosphides). Among these materials, a metal alloy having excellent conductivity attracts attention of many researchers, and is considered as an ideal candidate material for a noble metal catalyst. However, the alloy has poor durability in catalytic hydrogen evolution reaction, and particularly, in severe environments such as strongly alkaline electrolyte and high potential. Therefore, there is still a great challenge in developing a basic hydrogen-generating electrocatalyst with low cost, simple preparation process and high efficiency.
