| 摘 要： | 采用液相还原法制备了碳载PdPt催化剂(PdPt/C),电化学测试结果表明,尽管pd/C催化剂比PdPt/C催化剂对甲酸氧化具有更高的电催化活性,但长时间稳定性实验发现,甲酸在Pd/C催化剂上的氧化电流随时间衰减得很快,而PdPt/C催化剂对甲酸的氧化表现出更好的稳定性,比在Pd/C催化剂上有更高的稳定电流.

| Abstract: | Carbon supported Pd catalysts were prepared in simple reduction method.The results showed that the Pd/C catalyst possesses the higher catalytic activity than PdPt/C for formic acid oxidation.However,the stability on PdPt/C is much higher than on Pd/C and the reaction current is also higher on PdPd/C than on Pd/C. |
