The invention discloses a graphene-supported cobalt-doped titanium dioxide photocatalyst and a preparation method thereof. In the present invention, tetra-n-butyl titanate and cobalt nitrate are used as titanium source and cobalt source respectively to prepare precursor solution, and absolute ethanol, glacial acetic acid and PVP are used as auxiliary agent, and the precursor and auxiliary agent are uniformly mixed in proportion to obtain the solution. spinning solution; followed by high-voltage electrospinning to obtain initial PVP/Co-TiO 2 fibers; then calcined in a muffle furnace to obtain Co-TiO 2 nanofibers; finally, the Co-TiO 2 nanofibers were loaded into a vacuum freeze-drying method. On graphene, a Co-TiO 2 /RGO photocatalyst was obtained. The preparation method of the invention is simple, the production cost is low, the prepared composite photocatalyst has controllable morphology, high specific surface area, excellent optical performance, green environmental protection, good photocatalytic degradation effect of organic pollutants, and is widely used in the field of VOCs treatment. prospect. |
