Transition metal carbide (TMC) nanomaterials are promising alternatives to Pt, and are widely used as heterogeneous electrocatalysts for the electrochemical hydrogen evolution reaction (HER). In this work, a bromide-induced wet-chemistry strategy to synthesize Co2C nanoparticles (NPs) was developed. Such NPs exhibited high electrocatalytic activity (η = 181 mV for j = −10 mA·cm−2) and long-term stability (no obvious performance decrease after 4,000 cycles) for the HER. This study will pave the way for the design and fabrication of TMC NPs via a wet-chemistry method, and will have significant impacts on broader areas such as nanocatalysis and energy conversion.
