In this paper, we report a novel catalyst using NiP as a cocatalyst of Pt supported on graphene for methanol oxidation. The results reveal that the electrocatalytic activity and stability of the as-prepared catalyst for methanol oxidation are significantly enhanced by the addition of NiP. The reason for the increased activity and stability is ascribed to complex electron transfer between Pt, NiP, and graphene, which gives rise to the eventual promotion of CO electrooxidation reaction kinetics. The present study implies that the as-prepared Pt-NiP/graphene will be a promising candidate as an anode electrocatalyst in direct methanol fuel cells.
在本文中，我们报道了一种新型催化剂，该催化剂使用NiP作为负载在石墨烯上的Pt的助催化剂用于甲醇氧化。结果表明，通过添加NiP，所制备的用于甲醇氧化的催化剂的电催化活性和稳定性得到显著增强。活性和稳定性提高的原因归因于Pt、NiP和石墨烯之间复杂的电子转移，这最终促进了CO电氧化反应动力学。本研究表明，所制备的Pt-NiP/石墨烯有望作为直接甲醇燃料电池的阳极电催化剂。
