The invention provides a graphene-based high-entropy alloy nanoparticle and its preparation method and application. The preparation method of the graphene-based high-entropy alloy nanoparticle comprises: obtaining a precursor solution of the high-entropy alloy nanoparticle; The graphene powder is dispersed into the precursor solution to form a mixed solution; the mixed solution is subjected to suction filtration to obtain a self-supporting graphene oxide film loaded with metal salt; The graphene oxide self-supporting film of salt is subjected to radiation heating treatment to obtain graphene-based high-entropy alloy nanoparticles. Based on the above technical scheme, the rapid thermal decomposition of the metal salt adsorbed on the graphene carrier can be realized; the precipitation of the low-element alloy impurity phase can be effectively suppressed, and high-entropy alloy nanoparticles with a single phase structure can be obtained; and high-entropy alloy can be realized Simple and rapid large-scale synthesis of nanoparticles.
