synthesis of Pd/CuO nanoparticles by arc discharge of Cu in deionized (DI) water and electroless deposition of palladium was reported. The obtained nanoparticles were thoroughly characterized by using techniques like TEM, XRD, FE-SEM and EDS. The synthesized nanoparticles demonstrated excellent catalytic activity in Heck coupling reaction under aerobic conditions. The effects of catalyst composition, solvent
摘要 报道了通过在去离子 (DI) 水中电弧放电和钯的化学沉积来方便、温和且经济地合成 Pd/CuO 纳米颗粒。通过使用 TEM、XRD、FE-SEM 和 EDS 等技术对获得的纳米粒子进行了彻底的表征。合成的纳米粒子在有氧条件下的 Heck 偶联反应中表现出优异的催化活性。系统地研究了催化剂组成、溶剂和碱、芳基卤化物或烯烃种类对相应产物的影响。产品收率高、消除配体和均相催化剂、底物范围广和易于处理是该方法的重要特征。此外,催化剂可以重复使用五次以上的连续循环。
