Description

Efficient Ni-S-B hydrogen evolution electrode and preparation method and application thereof
Technical Field
The invention relates to the technical field of electrocatalytic hydrogen evolution, in particular to a high-efficiency Ni-S-B hydrogen evolution electrode and a preparation method and application thereof.
Background
Hydrogen energy is considered to be an ideal energy carrier and has attracted much attention from countries in the world due to its advantages of abundant reserves, cleanness, high efficiency, high energy density, etc. The hydrogen production by water electrolysis has the advantages of mature technology, simple process, no pollution, high hydrogen production purity and the like, and is an important method for producing hydrogen on a large scale and at low cost at present. However, in the actual production process, due to the existence of hydrogen evolution overpotential, the energy consumption in the water electrolysis process is increased, and the development of the water electrolysis industry is limited. Although noble metals such as Pt and Pd have low hydrogen evolution overpotential, the storage capacity is limited, the price is high, and the large-scale industrial application is difficult. Therefore, the research and development of the hydrogen evolution electrode with high hydrogen evolution catalytic activity and stability has important practical significance and practical value.
Among a plurality of non-noble metal hydrogen evolution electrodes, the Ni-S alloy has the advantages of high catalytic activity, simple manufacture, low cost and the like, so that the Ni-S alloy is widely concerned by researchers, and the introduction of other beneficial elements into the Ni-S alloy is an effective method for further improving the hydrogen evolution activity of the Ni-S alloy. Boron (B) is an important non-metallic element, and researches show that doping in the Ni alloy can reduce the desorption energy of hydrogen and improve the hydrogen evolution reaction speed, thereby increasing the hydrogen evolution catalytic activity of the electrode.
At present, the preparation method of the hydrogen evolution electrode mainly comprises the following steps: thermal decomposition, ion sputtering, mechanical alloying, electrodeposition, and the like. The material prepared by the thermal decomposition method has easily controlled components, simple process and low cost, but the strength of the plating layer is not high, and the types and the concentrations of the metal compounds which can be decomposed and generated are limited. The alloy electrodes with any proportion and various structures can be obtained by ion sputtering, but the methods have higher requirements on equipment and complex processes, and are not suitable for large-scale industrial production. The mechanical alloying method has simple process, low cost and high yield, but easily generates the defects of impurities, pollution, oxidation, stress and the like in the grinding process. Compared with the prior art, the electrodeposition has the advantages of simple process, low cost, uniform plating layer, easily-controlled thickness, wide plating layer components and material selectivity and the like, and is a preferred method for preparing the hydrogen evolution electrode in recent years.
Therefore, the present inventors have further studied and developed an efficient Ni-S-B hydrogen evolution electrode and a method for preparing the same, which are in turn resulted from the present invention.
