Based on the status quo of heterogeneous catalysts and the demand for green chemistry,porous nitrogen doped graphdiyne(PQ-GDY,synthesized by a"bottom-up"method)carbon material was used as the carrier to successfully prepare heterogeneous catalysts(Pd@PQ-GDY)with high nitro reduction catalytic activity through palladium(Pd)loading.The composite material was comprehensively characterized and theoretically calculated through field emission scanning electron microscopy(FE-SEM),X-ray photoelectron spectroscopy(XPS),and density functional theory(DFT).The results showed that the catalyst achieved efficient loading of Pd(0)on PQ-GDY and its catalytic activity was significantly improved,which is 23 times higher than that of Pd(0)generated in situ without loading PQ-GDY.The reduction conversion rates of 10 nitroaromatic hydrocarbons catalyzed by Pd@PQ-GDY are all higher than 96.5%.Pd@PQ-GDY exhibits good functional group compatibility.
