| 摘 要： | 分别以硼氢化钠和乙二醇为还原剂,经络合还原法制备了炭载钯(Pd/C)催化剂。透射电镜(TEM)和X射线粉末衍射谱(XRD)结果表明,以乙二醇为还原剂制备的Pd/C催化剂中Pd粒子具有较小的粒径、均匀的粒径分布和较大的相对结晶度,Pd粒子的平均粒径和相对结晶度分别为(4.2±2)nm和1.88。电化学测试结果显示,Pd/C催化剂具有较大的电化学活性面积,对甲酸氧化表现出较高的电催化活性和稳定性。 |

| Abstract: | The carbon supported Pd(Pd/C) catalyst was prepared by way of complex reduction method respectively with sodium borohydride and ethylene glycol as reducing agents.The transmission electron microscopy(TEM) and X-ray diffraction(XRD) spectrum characterizations indicate that Pd nanoparticles of the Pd/C catalyst prepared by ethylene glycol have a smaller particle size,uniform particle size distribution and higher relative crystalinity.The average size and relative crystalinity of the Pd nanoparticles are as small as(4.2±2) nm and 1.88,respectively.The electrochemical measurements demonstrate that the electrocatalytic activity and stability of the Pd/C catalyst prepared by ethylene glycol for formic acid oxidation are better than that of the Pd/C catalyst prepared by sodium borohydride. |
| Keywords: | Pd/C catalyst complex reduction ethylene glycol formic acid oxidation catalysis technology |
