摘要
采用甲基丙烯酸锌加速还原氯化钯(Pd Cl2)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.
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.
