过渡金属碳化物（TMC）纳米材料是一种很有前途的铂替代物，被广泛用作电化学析氢反应（HER）的多相电催化剂。在这项工作中，溴诱导的湿化学策略合成Co 2C纳米粒子（NPs）的发展。该纳米粒子具有较高的电催化活性（η= 181 mV（j = −10 mA·cm−2））和长期稳定性（4,000次循环后性能无明显下降），为湿化学法设计和制备TMC纳米粒子奠定了基础，并将在纳米催化和能量转换等更广泛的领域产生重大影响。
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 forj= −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.
