以苯甲醇为溶剂和还原剂，氯钯酸为前躯体，在适量聚乙烯吡咯烷酮( PVP)存在下，微波辐照加热150sec得到雪花状的钯纳米颗粒，并对制备的产物进行了TEM、 XRD表征。并以硝基苯为底物探讨了没有负载的雪花状Pd纳米颗粒的催化活性和选择性。
以苯甲醇為溶劑和還原劑，氯鈀痠為前軀體，在適量聚乙烯吡咯烷酮( PVP)存在下，微波輻照加熱150sec得到雪花狀的鈀納米顆粒，併對製備的產物進行瞭TEM、 XRD錶徵。併以硝基苯為底物探討瞭沒有負載的雪花狀Pd納米顆粒的催化活性和選擇性。

The flakes Pd nanostructure with ordered branches was successfully prepared via microwave irradiation with benzyl alcohol as a solvent in the presence of polyvinylpyrrolidone( PVP). The as-synthesized Pd was characterized by transmission electron microscopy and X-ray photoelectron spectroscopy. The catalytic activities and selectivity of the flakes Pd nanoparticles without any supported were investigated preliminarily by means of the hydrogenation reaction of nitrobenzene.
