Abstract
Development of oxygen evolution reaction (OER) catalysts with reduced precious metal content while enhancing catalytic performance has been of pivotal importance in cost-effective design of acid polymer electrolyte membrane water electrolyzers. Hollow multimetallic nanostructures with well-defined facets are ideally suited for saving the usage of expensive precious metals as well as boosting catalytic performances; however, Ir-based hollow nanocatalysts have rarely been reported. Here, a very simple synthetic scheme is reported for the preparation of hollow octahedral nanocages of Co-doped IrCu alloy with readily tunable morphology and size. The Co-doped IrCu octahedral nanocages show excellent electrocatalytic activity and long-term durability for OER in acidic media. Notably, their OER activity represents one of the best performances among Ir-based acidic OER catalysts © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
