Herein, the study reported extraordinary chemoselective reduction with selectivity (>99%) by the catalytic transfer hydrogenation of various α,β-unsaturatedketones with a catalyst of NiPd alloy nanoparticles decorated on mesoporous graphitic carbon nitride (NiPd/mpg-C3N4) under mild conditions in a water/methanol medium. NiPd alloy NPs were synthesized by the reduction of metal salts in oleylamine
本文中,研究报告称,通过在介孔石墨氮化碳上装饰NiPd合金纳米粒子的催化剂(NiPd / mpg-C 3 N 4)催化转移各种α,β-不饱和酮,可实现非凡的化学选择性还原(> 99%)。)在水/甲醇介质中的温和条件下。通过在硼烷-叔丁胺的帮助下在油胺(OAm)溶液中还原金属盐,合成NiPd合金NP ,然后通过液相自组装法在mpg-C 3 N 4上修饰。通过TEM,XRD和ICP-MS对NiPd / mpg-C 3 N 4纳米催化剂进行了表征。NiPd / mpg-C 3 N4纳米催化剂是用于化学选择性还原α,β-不饱和酮的高活性催化剂,所有有机化合物均以高收率和99%的选择性转化。另外,该催化剂可以重复使用五次而不会显着降低反应产率。
