摘要

本文报道了一种涂覆在Ti网上的三维Ni3N-CeO2纳米杂化物(Ni3N-CeO2 /TM)作为电化学碱性析氢反应的高性能催化剂。在1.0 M KOH溶液中，仅需要80 mV过电位即可提供10 mA cm?2的电流密度。此外，Ni3N-CeO2 /TM保持了至少24小时的电催化性能，达到了大约100%的法拉第效率。

High-performance alkaline hydrogen evolution electrocatalyzed by a Ni3N–CeO2 nanohybrid†

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.
