NOVELTY - A boron nitrogen-doped graphite-supported palladium catalyst preparing method involves preparing an oxidized graphene by the Hummers synthesis method, co-heating graphene with boric acid to obtain boron doped graphene oxide, impregnating in ammonia, simultaneously reducing boron-doped oxide graphene, filtering under the protection of nitrogen at 400-450 degrees C, and loading potassium borohydride and palladium metal, to obtain product. USE - Method for preparing boron nitrogen-doped graphite-supported palladium catalyst.
