METHOD FOR PREPARING EFFICIENT HYDROGEN EVOLUTION REACTION CATALYST IR@NBD-C AND USE THEREOF

Publication No.: WO2021227382A1 18/11/2021

CN_111558390_A

Absstract of: WO2021227382A1

Provided is a method for preparing Ir@NBD-C, i.e. an efficient hydrogen evolution reaction (HER) catalyst. The method comprises: mixing a defective carbon substrate with deionized water until uniform; then adding iridium trichloride hydrate, melamine and boric acid, mixing same until uniform, and drying same to obtain a powder sample; and calcining same at 600±50ºC under an inert atmosphere for 1-2 h to obtain a hydrogen evolution reaction catalyst Ir@NBD-C-600. According to the efficient hydrogen evolution reaction catalyst material, by utilizing the bundling effect of nitrogen and boron on metal single atoms and metal clusters, the growth rate of particles is decreased, such that the diameter of noble metal nanoparticles is reduced to less than 2 nm, and uniform distribution is realized on a carbon substrate. The reduction in particle diameter makes the catalyst have a higher specific surface area, and also makes the catalyst expose more active surfaces, which is beneficial for catalysis. The overpotential of the catalyst under a certain current density during a HER process is thus significantly reduced; and the bundling effect of nitrogen and boron makes the metal nanoparticles maintain a good stability during the cycle.
