Palladium-loaded carbon nitride and application thereof in reduction of photocatalytic oxaggolil intermediate

The invention discloses palladium-loaded carbon nitride, a preparation method thereof and application of the palladium-loaded carbon nitride in reduction of a photocatalytic hylagoride key intermediate, and belongs to the technical field of photocatalytic materials. One or more of cyanamide, dicyandiamide, thiourea, urea and melamine are used as precursors, bulk-phase carbon nitride is synthesized through a thermal polymerization reaction, then inorganic salt is added, high-crystallinity carbon nitride is synthesized through a molten salt method, palladium salt is used as a metal source, and the palladium-loaded carbon nitride is synthesized through a photo-reduction method. The palladium-loaded carbon nitride prepared by the invention can be well dispersed in water and various organic solvents and kept stable, has good visible light response capability, and can show good activity of photocatalytic reduction of 2-fluoro-6-trifluoromethylbenzaldoxime into 2-fluoro-6-trifluoromethylbenzylamine under the irradia
