Vapor Phase Dealloying Derived Nanoporous Co@CoO/RuO₂ Composites for Efficient and Durable Oxygen Evolution Reaction (Adv. Funct. Mater. 17/2023)

Oxygen Evolution Reaction Electrocatalyst In article number 2214124, Pan Liu and co-workers constructed a 3D bicontinuous nanoporous Co@CoO/RuO2 composite with tunable ligament sizes and highly stable CoO/RuO2 interface using vapor phase dealloying method. The composite catalyst delivers an ultralow overpotential of 198 mV at 10 mA cm−2 and long-term stability of 50 h. This study provides powerful support for the functionalization of vapor phase dealloying applications.
