摘要：制备了不同Pt/Au原子比的活性炭负载Au-Pt催化剂(Au-Pt/C),研究了Au/Pt原子比对Au-Pt/C催化剂氧还原电催化性能和抗甲酸性能的影响。结果表明,与Au/C催化剂相比,Au-Pt/C具有更好的电催化性能。当Pt/Au原子比从0/50增加到2/48时,Au-Pt/C催化剂表现出良好的氧还原电催化性能和抗甲酸性能;但是当Pt/Au原子比增加到3/47时,该催化剂的抗甲酸性能有所下降。Pt/Au原子比为2/48的Au-Pt/C可以用作直接甲酸燃料电池(DFAFC)的阴极催化剂。
Active carbon supported Au-Pt catalyst（Au-Pt/C） with different Pt/Au atom ratios was prepared and the effect of Pt/Au atom ratio on the electrocatalytic performance of Au-Pt/C in direct formic acid fuel cell（DFAFC） like the oxygen reduction ability and tolerance to formic acid was investigated.Comparing with Au/C catalyst,the Au-Pt/C catalyst exhibits better electrocatalytic performance towards the reduction of oxygen.With the increase of Pt/Au atom ratio from 0/50 to 2/48,Au-Pt/C catalyst shows excellent electrocatalytic ability and formic acid tolerance.However,when Pt/Au atom ratio is further raised to 3/47,the formic acid tolerance of Au-Pt/C is decreased.As a result,Au-Pt/C catalyst with a Pt/Au atom ratio of 2/48 is appropriate as the cathodic catalyst in DFAFC.
