本文介绍了在Au表面直接生长铂纳米棒的方法。通过电化学测试考察了它们对甲醇氧化的催化性能。循环伏安测试表明，金纳米颗粒负载的铂纳米棒对甲醇电氧化具有良好的稳态催化活性和较高的催化活性。随着时间的推移，它们还表现出稍慢的电流衰减。
This paper describes the preparation of Pt nanorods by directly growing them on the surface of Au. Electrochemical measurements were performed to investigate their catalytic performance towards methanol oxidation. It was found from cyclic voltammetry that the Pt nanorods supported on Au nanoparticles had excellent steady-state catalytic activity and high catalytic activity for methanol electrooxidation. They also exhibited a slightly slower current decay over time.
