摘要:

金属铂是最高效的氧还原反应催化剂而被广泛应用于质子交换膜燃料电池,但其高成本阻碍了燃料电池的商业化进程。此专论主要总结了近年来核-壳结构纳米催化剂的设计、合成及在燃料电池中的应用,讨论了多种提高核-壳结构纳米催化剂的策略包括去合金化、形貌控制、表面改性等,以及在放大制备及燃料电池测试中遇到的问题。

Abstract:

The high cost of platinum in catalyst layers hinders the commercialization of proton exchange membrane fuel cells. This Account reviews recent progress on core-shell nanostructures for oxygen reduction reaction (ORR) in acidic media, which is the cathodic reaction in fuel cells. The synthesis, characterization and evaluation of different types of core-shell electrocatalysts are summarized. Various strategies to improve the performance of core-shell electrocatalysts, including dealloying, morphology control, and surface modification are presented. The issues of mass production and fuel cell performance of core-shell electrocatalysts are also discussed.

Key words: Core-shell structure, Proton exchange membrane fuel cell, Electrocatalysis, Platinum alloy, Palladium, Shape control
