| 摘 要： | 采用不同体系制备了碳载Pd催化剂(Pd/C),发现在乙二醇体系中制备的Pd/C催化剂对甲酸氧化具有最负的峰电位和最低的起始氧化电位,Tafel斜率最小为155mV,并且在1h的计时电流曲线测试表明,用乙二醇体系制备的Pd/C-3催化剂具有较高的稳定电流。TEM结果可以看出,用乙二醇体系制备的Pd/C催化剂Pd粒子在活性碳表面分散得最好,Pd粒径的大小约为4～5nm。

| Abstract: | Carbon supported Pd catalysts were prepared in different systems. The results showed that the Pd/C catalyst which prepared in glycol had the most negative peak potential, the lowest onset potential and the smallest Tafel slope that is 155 mV. The catalyst Pd/C-3 has the highest current density during 1 hour. TEM images show that the Pd particles which is about 4-5 nm in Pd/C-3 catalyst dispersed well compared with other catalysts. |
