The method comprises the following specific steps: firstly, preparing B-NiO/graphene as a precursor by using nickel nitrate, graphene oxide and sodium borohydride as reactants through a gas-phase synthesis method; further using sodium hypophosphite to heat the precursor under the protection of gas for phosphorization to obtain N, B-Ni2P/graphene composite electrolytic water catalyst.
Description
Technical Field
The invention relates to a preparation method of a graphene-loaded nitrogen-boron-doped nickel phosphide electrolyzed water catalyst, belonging to the technical field of novel inorganic nano functional materials.
Background
Hydrogen (H)2) Are considered as clean energy carriers to replace fossil fuels due to their high energy density and environmental friendliness. Currently, large-scale high-purity Hydrogen (HER) produced by cathodic hydrogen evolution reactions through water electrolysis is considered a cost-effective and viable process. So far, electrocatalysts with high catalytic hydrogen production catalytic efficiency have been limited to expensive and scarce noble metal catalysts (e.g., platinum), which severely hamper their practical application. For this reason, many non-noble metal-based electrocatalysts have been developed with high efficiency in acidic and alkaline electrolytes, including transition metal nitrides, sulfides, selenides, carbides, phosphides, and the like. However, most of the catalysts having excellent hydrogen evolution activity in acidic or basic media have unsatisfactory catalytic activity in neutral media due to their low conductivity, low intrinsic catalytic activity, and the like. In addition, in an acidic or alkaline medium, the strong acid and the strong base are easy to corrode an electrolysis instrument and a catalyst, so that the method is low in environmental and economic friendliness. In contrast, electrochemical water splitting in neutral media can effectively reduce the overall cost of an electrolyzed water system because expensive proton exchange membranes are not required. Therefore, the development of efficient and stable neutral HER electrocatalysts is an important basis and key link for the development of hydrogen production technology by water electrolysis, but still faces greater challenges.
So far, Transition Metal Phosphide (TMP), including Ni2P,Ni12P5,CoP,Co2P, NiCoP, FeP and MoP, etc. are widely used as substitutes for Pt-based catalysts due to their non-metallic characteristics, high electrocatalytic properties and significant soil abundance. However, the monotonic morphology, small specific surface area, and low conductivity and low stability severely limit their practical applications. In order to solve the above problems and further improve the electrochemical activity, several strategies to solve the above key problems have been proposed, and some progress has been made so far. For example, increasing the specific surface area of TMP nanostructures by surface roughening or porous structures can not only create more exposed active sites, but can also enhance water moleculesDiffusion and rapid release of gaseous products. Based on earlier stage research, the invention develops a preparation method of the full-pH electrolyzed water hydrogen evolution catalyst with low cost, simplicity, convenience, practicability and low energy consumption, and Ni is regulated and controlled by doping boron and nitrogen2P-electron structure, enhancement of Ni by graphene loading2P conductivity, successfully synthesizes the graphene loaded nitrogen boron doped nickel phosphide (N, B-Ni)2P/graphene) nanoplatelets and for stable HER catalysis. N, B-Ni obtained by synergistic regulation of water and hydrogen binding energy2P/graphene shows significant HER activity in acidic, basic and neutral electrolytes.
