Abstract

The invention relates to the technical field of new materials, and discloses a method for preparing black phosphorus-graphene heterojunction loaded nickel nitride, comprising the following steps: S1) Weigh red phosphorus powder and cellulose powder respectively, and disperse them in deionized water , carry out ultrasonic treatment to obtain a dispersion liquid containing a combination of red phosphorus and cellulose; S2) add nickel nitride particles into the dispersion liquid, stir, put the stirred mixed solution in a vacuum oven and dry to constant weight to obtain The mixture; S3) put the mixture into a high-voltage discharge chamber, and process it through high-voltage discharge to obtain a crude product; S4) disperse the crude product in absolute ethanol, inject it into a centrifuge tube, and then put it into a centrifuge for centrifugal purification to obtain a refined product , put into a vacuum oven and dry to constant weight, that is, black phosphorus-graphene heterojunction loaded nickel nitride is obtained, and the product quality is high and the cost is low; also proposed to implement the above black phosphorus-graphene heterojunction loaded nickel nitride The device for the preparation method of nickel nitride has high production efficiency.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a method for preparing black phosphorus-graphene heterojunction loaded nickel nitride and a preparation device thereof. Background technique [0002] Hydrogen energy is recognized as a clean energy source. At present, the main method of hydrogen production is electrolysis of water. The reaction of electrolysis of water is mainly composed of hydrogen evolution reaction (HER reaction) at the cathode and oxygen evolution reaction (OER reaction) at the anode. [0003] Since the OER reaction is a four-electron transfer process, its high overpotential and slow kinetics limit the efficiency of hydrogen evolution, and it is necessary to develop efficient and durable electrocatalysts for oxygen evolution reaction in electrolysis of water. [0004] The existing OER electrocatalysts for oxygen evolution reaction represented by ruthenium-based and iridium-based catalysts are expensive....
