本文从阴极反应和阳极反应两个方面综述了质子交换膜燃料电池电催化剂的最新进展,并着重介绍了催化剂的合理设计。这些设计基于使用模型表面研究获得活性位点,包括用于阳极电氧化反应的高指数刻面Pt和Pt合金纳米晶体,以及用于阴极氧还原反应(ORR)的Pt基合金/核-壳结构和碳基非贵金属催化剂。高指数纳米晶体,合金纳米粒子,和支持效果突出的阳极催化剂,并在ORR电催化剂与新的结构和不同的组合物的阴极催化剂强调当前的发展。对碳基非贵金属催化剂的活性中心结构、催化性能和在燃料电池中的稳定性进行了综述。此外,还介绍了先进燃料电池电催化剂的发展前景和现状。
AbstractRecent progresses in proton exchange membrane fuel cell electrocatalysts are reviewed in this article in terms of cathodic and anodic reactions with a focus on rational design. These designs are based around gaining active sites using model surface studies and include high-index faceted Pt and Pt-alloy nanocrystals for anodic electrooxidation reactions as well as Pt-based alloy/core–shell structures and carbon-based non-precious metal catalysts for cathodic oxygen reduction reactions (ORR). High-index nanocrystals, alloy nanoparticles, and support effects are highlighted for anodic catalysts, and current developments in ORR electrocatalysts with novel structures and different compositions are emphasized for cathodic catalysts. Active site structures, catalytic performances, and stability in fuel cells are also reviewed for carbon-based non-precious metal catalysts. In addition, further developmental perspectives and the current status of advanced fuel cell electrocatalysts are provided.Graphical Abstract
