| 摘 要： | 采用甲基丙烯酸锌加速还原氯化钯(PdCl2) 溶液中的钯离子(Pd 2+)为钯(Pd) 纳米微球, 进而用得到的钯纳米微球直接制备钯/氧化钯(Pd/PdO) 纳米复合微球. 通过扫描电子显微镜(SEM)、 透射电子显微镜(TEM)、 粉末X射线衍射分析(XRD)及X射线光电子能谱分析(XPS) 等方法对 Pd/PdO 纳米复合微球进行表征, 结果表明, 制备的纳米复合微球为表面粗糙、 大小均一的纳米微球. 采用紫外-可见吸收光谱(UV-Vis) 等方法考察了 Pd/PdO 纳米复合微球在对硝基苯酚(4-NTP) 还原反应中的催化性能, 发现其具有良好的催化活性和循环稳定性.

| Abstract: | Zn(MAA)2 was introduced to accelerate the reduction of Pd 2+ into Pd in PdCl2 solution. The final sample Pd/PdO nanocomposite microspheres were prepared through calcination. Furthermore, the Pd/PdO nanocomposite microspheres were characterized by scanning electron microscopy(SEM), transmission electron microscopy(TEM), X-ray powder diffraction analysis(XRD) and X-ray photoelectron spectroscopy(XPS). Moreover, UV-visible adsorption spectra were recorded to investigate the performance of Pd/PdO nanocatalysts for the reduction reaction of 4-NTP. |
