摘　　要：用间歇式微波法制备了不同Pt∶Co原子比的碳载PdCo合金催化剂(PdCo/C),发现在酸性溶液中Pd∶Co原子比2∶1催化剂对甲酸的电氧化有良好的催化活性和稳定性。从H在电极表面的吸脱附峰计算出来的结果表明,催化剂中加入一定比例的金属Co能够增加催化剂的电化学比表面。Carbon supported PdCo catalysts of different atomic ratios of Pd：Co were prepared by the method of pulse microwave. The results showed that the PdCo/C catalyst with Pd：Co atomic ratio of 2：1 had the best electrocatalytic activity and stability for formic acid oxidation among other catalysts and the catalyst has the largest electrochemical specific surface area which, indicated the effect of Co in the catalyst.
