The core of the problem: Electrocatalysts need to be highly active and durable under harsh reactive environments in order to meet the requirements for future automotive applications. Platinum-group-metal-based core–shell and core–shell-like nanostructures have great potential in the design of multifunctional catalysts for the oxygen reduction reaction (ORR; see picture).
