Abstract 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.
