摘要/Abstract

摘要： 使用去合金法制备了孔径和孔壁均匀的纳米多孔金(NPG)电极.研究发现NPG对甲酸、甲醛的氧化具有很高的电催化活性.如在NPG基体再沉积微量的铂,不仅明显改善了NPG的结构稳定性,而且由于Pt、Au两组分之间的协同效应而使该催化剂对有机小分子的电催化氧化具有比纯铂更高的催化活性和更强的抗催化毒物能力.

关键词: 纳米多孔金, 电催化, 铂, 循环伏安法, 协同效应

Abstract: The nanoporous gold(NPG) electrodes with uniform pore sizes and ligaments were prepared by using a simple dealloying method.The as-prepared NPG showed high catalytic activity towards the oxidation of formic acid and formaldehyde.After tiny amount of platinum was deposited onto the NPG substrate,not only the structure stability of NPG was greatly improved,but also the Pt-Au bimetallic catalysts displayed the better catalytic activity and the stronger poison resistance towards the electrooxidation of small organic molecules than the bulk platinum due to synergistic effect between Au and Pt compositions.

Key words: nanoporous gold(NPG), electrocatalysis, platinum, cyclic voltammetry, synergistic effect
