The invention discloses a preparation method and application of a microwave-ultraviolet light catalyst, and belongs to the technical field of photocatalysts. The preparation method of the microwave-ultraviolet light catalyst comprises the steps that titanium dioxide is prepared, Co3O4 is prepared, and TiO2 and Co3O4 are mixed and coated on a Ni net to obtain a supported Co3O4-TiO2 catalyst, wherein the supported Co3O4-TiO2 catalyst is applied to organic matter pollution treatment, and is used for degrading organic pollutants under microwave-ultraviolet radiation. The catalyst prepared by the method can generate a hot spot effect under microwave radiation, the actual temperature of a hot spot on the surface of the catalyst is far higher than the apparent temperature, and a catalytic reaction is greatly promoted; organic matters (VOCs) can be effectively converted into inorganic mineralized molecules under the radiation of microwaves and ultraviolet light, so that the VOCs are thoroughly degraded; and the prepa
