在水溶液中，通过快速、一步、高效的方法成功地制备了多孔钯纳米粒子。所开发的方法非常简单，只需将四氯钯酸钠、聚乙烯吡咯烷酮和对苯二酚混合，并在70 °C下加热15 min。利用透射电子显微镜、选区电子衍射、电感耦合等离子体发射光谱仪、X射线衍射、能量色散X射线能谱和X射线光电子能谱对样品的结构和成分进行了分析。电化学催化性能测试结果表明，所制备的多孔Pd纳米粒子对乙醇和甲酸的电氧化具有上级催化活性。
Porous Pd nanoparticles are successfully prepared by a rapid, one-step, and efficient route with high yield in aqueous solution. The developed method is very simple, just by mixing sodium tetrachloropalladate, polyvinylpyrrolidone and hydroquinone and heated at 70 °C for 15 min. The structure and composition are analyzed by transmission electron microscope, selected-area electron diffraction, inductively coupled plasma optical emission spectrometer, X-ray diffraction, energy dispersive X-ray spectrum and X-ray photoelectron spectroscopy. Electrochemical catalytic measurement results prove that the as synthesized porous Pd nanoparticles exhibit superior catalytic activity towards ethanol and formic acid electrooxidation.
