Description
Technical Field
The invention belongs to the technical field of hydrogen production, and particularly relates to a boron-doped graphene nanoribbon nickel-loaded monatomic catalyst and a preparation method thereof.
Background
The hydrogen production by electrolyzing water is a convenient and efficient hydrogen production method with development prospect. The water electrolysis hydrogen production reaction occurs on the surface of the electrode and comprises two basic reactions of cathode hydrogen evolution reaction and anode oxygen evolution reaction. For the hydrogen production reaction by water electrolysis, how to effectively improve the catalytic activity of the catalytic material, reduce the opening overpotential and the tafel slope of the hydrogen evolution reaction, and improve the long-range stability and the cycle stability of the electrode material is the focus and key point of research in the field of electrocatalysis. Generally, a noble metal platinum-based catalyst has excellent electrocatalytic hydrogen evolution activity due to its own special surface electron state and good d-electron center position; however, the development process of the hydrogen evolution catalytic material is severely restricted due to the low earth-crust abundance of the platinum-based material and the high price thereof. In recent years, non-noble metal based monatomic catalysts have good hydrogen adsorption and desorption energy due to monatomic size effect of the catalysts, and thus the catalysts are expected to have good electrocatalytic hydrogen evolution performance. So far, the application of non-noble metal-based monatomic catalyst in the field of hydrogen evolution by electrocatalysis hydrolysis still has more problems, one is that the load of the monatomic-based catalyst is usually too small because no metal bond is generated in the whole system; secondly, the transition metal chalcogenide is a semiconductor and has a slow electron transfer rate, so that the adoption of a substrate with good conductivity to load the catalyst is crucial to the electrocatalyst; and thirdly, the cycling stability of the prepared electrode is a problem, and the stability of the prepared electrocatalyst supported electrode is poor. In summary, how to design and prepare a high-loading monatomic electrolytic water hydrogen evolution catalytic material with high catalytic activity and good stability is a problem to be solved at present.
