The invention relates to the technical field of photocatalysts, in particular to a composite photocatalyst and a preparation method and application thereof. The invention discloses a preparation method of a composite photocatalyst, which comprises the following steps: dispersing titanium dioxide in a solvent, then adding oxygen-doped carbon nitride for stirring, and sintering the solid substance obtained by the stirring to obtain a composite photocatalyst . The preparation method of the composite photocatalyst provided by the invention adopts the thermal polymerization method, has few raw materials, simple synthesis process, good repeatability, basic conditions for large-scale production, and high application potential and use value. The composite photocatalyst prepared by this preparation method can degrade PPCPs under simulated sunlight, and has excellent photocatalytic effect. |
