The invention provides a photoresponse type boron carbide-based nanoparticle catalytic material and a preparation method and application thereof.The preparation method comprises the steps that boron carbide, cobalt-nickel alloy and zinc oxide are taken to be mixed and subjected to ball milling, and then a mixture is obtained; the preparation method comprises the following steps: adding absolute ethyl alcohol into polyvinylpyrrolidone, stirring, adding tetrabutyl titanate, and continuously stirring to obtain a mixed solution; mixing the mixture with the mixed solution, transferring into a reaction kettle containing graphene, putting into the reaction kettle for hydrothermal reaction, cooling, collecting solid particles, drying, sintering with inert gas, and cooling to obtain the light response type boron carbide-based nano-particle catalytic material. The light response type boron carbide-based nanoparticle catalytic material prepared from boron carbide, cobalt-nickel alloy, zinc oxide and the photocatalyst is high in specific surface area, can improve the photocatalytic activity, and has a good catalytic degradation effect on artificially synthesized dyes such as rhodamine B.
