In this communication, a 3D Ni₃N–CeO₂ nanohybrid coated onto Ti mesh (Ni₃N–CeO₂/TM) is reported as a high-performance catalyst for the electrochemical alkaline hydrogen evolution reaction. In 1.0 M KOH solution, only an 80 mV overpotential is required to deliver a current density of 10 mA cm⁻². In addition, Ni₃N–CeO₂/TM retains its electrocatalytic properties for at least 24 h and reaches approximately 100% faradaic efficiency.

高性能碱性析氢利用Ni电催化₃的N-的CeO ₂纳米杂化物†

在这种交流中，据报道，涂覆在Ti网孔上的3D Ni ₃ N–CeO ₂纳米杂化物（Ni ₃ N–CeO ₂ / TM）是电化学碱性氢释放反应的高性能催化剂。在1.0 M KOH溶液中，仅需要80 mV的超电势即可提供10 mA cm ^-2的电流密度。此外，Ni ₃ N–CeO ₂ / TM保持其电催化性能至少24小时，并达到约100％的法拉第效率。
