英文摘要：

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.
