NOVELTY - Preparing boron-doped graphene nanoribbon supported nickel monoatomic catalyst comprises adding multi-walled carbon nanotubes to a strong oxidant, oxidizing at a certain temperature, and obtaining graphene nanoribbons after multiple centrifugal cleaning. The graphene nanoribbons are sonicated, then a boron precursor is added, and boron doping is performed at a high temperature reaction in a hydrothermal kettle to obtain boron-doped graphene nanoribbons. The boron-doped graphene nanoribbons are dissolved in deionized water with stabilizing agent, and the nickel precursor is added under continuous stirring, followed by rapid freeze-drying in liquid nitrogen. The reaction is then heated to a certain temperature under an atmosphere protection reaction, and then annealed at a gas protection temperature, and after the system is naturally cooled to room temperature, washed with anhydrous ethanol multiple times, and vacuum dried to obtain a graphene nanobelt supported nickel single atom. USE - Method for preparing boron-doped graphene nanoribbon supported nickel monoatomic catalyst used for hydrogen production(claimed). ADVANTAGE - The method enables to prepare boron-doped graphene nanoribbon supported nickel monoatomic catalyst, which is suitable for industrial production and has high economic value and has simple preparation process.
