The invention provides a preparation method of nickel nitride graphene composite material-loaded previous metal nanoparticle. The preparation method comprises the steps of preparing a nickel nitride graphene composite material; respectively washing a nickel nitride nanosheet and a graphene nanosheet layer material with ethyl alcohol and water after ball-milling under argon protection, performing filtering to obtain the nickel nitride graphene composite material, and performing vacuum drying and collection; and dispersing the nickel nitride graphene composite material in the ethyl alcohol, adding a stabilizing agent and a metal precursor after ultrasonic treatment, continuing to perform ultrasonic stirring, adjusting pH to be 9-11, adding a reducing agent, continuing to stir, and obtainingthe nickel nitride graphene composite material-loaded previous metal nanoparticle after vacuum drying. The nickel nitride graphene composite material carrier is combined very well with previous metal,the electrochemical activ
