摘要
以氯钯酸为前驱体、三缩四乙二醇(TEG)为溶剂和还原剂、聚乙烯吡咯烷酮(PVP)为保护剂、KI为添加剂,微波辐照加热90s,合成了形貌单一、大小均匀的Pd纳米立方块,平均粒径为30nm,具有很高的结晶度,属于面心立方(fcc)结构。所合成的Pd纳米立方块对卤代苯和苯硼酸的Suzuki偶联反应具有良好的催化活性,且具有较高的催化稳定性。
Monomorphologic and uniform Pd nanocubes were synthesized with palladium chloride as precursor,tetraethylene glycol（TEG）as both solvent and reducing agent,polyvinylpyrrolidone（PVP）as stabilizer in the presence of an appropriate amount of KI under microwave irradiation for 90 s.The structure of Pd nanocubes obtained was face-centered cubic（fcc）with higher crystallinity,and the average particle size was 30 nm.Pd Nanocubes obtained were used in Suzuki coupling reaction and demonstrated better catalytical properties.
