基于非均相催化剂的发展现状以及绿色化学的需求,以多孔氮掺杂石墨二炔(PQ-GDY,"自下而上"法合成)碳材料为载体,经钯负载成功制备了具有高硝基还原催化活性的非均相催化剂(Pd@PQ-GDY).通过场发射扫描电子显微镜(FE-SEM)、X射线光电子能谱(XPS)、密度泛函理论(DFT)对该复合材料进行了综合表征及理论计算.结果表明:Pd@PQ-GDY实现了PQ-GDY对Pd(0)的高效负载,催化活性显著提高,是原位生成且未负载PQ-GDY的Pd(0)催化活性的23倍;其催化的10种硝基芳烃的还原转化率均高于96.5%,且展现了出良好的官能团兼容性.
Heterogeneous reduction of nitroaromatic hydrocarbons catalyzed by N-doped graphdiyne materials supported Palladium
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.
