纳米技术的迅速发展促进了核壳纳米粒子作为一种新型功能材料的产生。通过理性设计核与壳的组成,可以构建一系列具有功能可调性的核壳纳米材料。该类材料可以作为燃料电池中氧还原反应(ORR)的阴极电极,并表现了卓越的电催化性能。本文以不同化学属性为核壳分类,依托ORR机理,综述了近几年核壳结构电极材料在ORR中的应用,提出了存在的挑战,以期为解决能源转换与储存问题提供思路。

The rapid development of nanotechnology has promoted the production of core-shell nanoparticles as a new type of functional material. By rationally designing the core and shell composition,a series of core-shell nanomaterials with functional tunability can be constructed. The material can be used as a cathode electrode for oxygen reduction reaction（ORR） in fuel cells and exhibits excellent electrocatalytic performance. Based on the classification of different chemical properties of core and shell,this article reviews the application of core-shell electrode materials in ORR in recent years and proposes some existing challenges in order to provide ideas for current solutions to energy conversion and storage problems.
