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