| 乙醇电催化氧化反应是直接乙醇燃料电池的核心步骤之一,制备高效稳定的电催化材料已经成为提升其电催化反应效率和选择性的关键。贵金属基纳米催化剂以其独特的物理和化学特性,在乙醇电催化氧化中表现出优异的电催化性能,在燃料电池领域具有重要的应用前景。近来贵金属基乙醇氧化催化剂受到广泛关注并取得系列重要研究进展。本文主要从催化剂元素组成调变形成多元素协同作用、形貌调控暴露高指数晶面和载体选择提升分散性等三个方面对贵金属基纳米催化剂性能的影响进行综述,为后续研究设计高效稳定的直接乙醇燃料电池催化剂提供参考。 |
| 英文摘要: |
| The electrocatalytic oxidation of ethanol is one of the core steps of direct ethanol fuel cells (DEFCs), and the design and preparation of highly-efficient and stable electrocatalytic materials has become the key to improve the reaction efficiency and selectivity. With their unique physical and chemical properties, precious metal-based nanocatalysts exhibit excellent electrocatalytic performance in ethanol oxidation, so they have important application prospects in the field of fuel cells. This article mainly reviews the effects of noble metal-based nanocatalysts on the performance of noble metal-based nanocatalysts from three aspects: the multi-element synergy formed by the modulation of the composition of the catalyst elements, the exposure of high-index crystal planes by morphology control, and the choice of carrier to enhance the dispersion, which may pave a new pathway for the subsequent design of efficient and stable catalysts for DEFCs. |
