摘要
The present work reports oxygen evolution reaction (OER) activity in metallic V 4 AlC 3 bulk powders prepared by solid-state reactions for the first time. An ultralow overpotential of 253 mV at the current density of 10 mA cm −2 and an excellent stability are observed, demonstrating that V 4 AlC 3 bulk powder can be used as an excellent new type of OER catalyst with low-cost for mass production.
