Abstract

In this Communication, we report a 3D porous Ni-CeO₂ nanosheet array supported on a Ti mesh (Ni-CeO₂/TM) as an excellent electrocatalyst toward the alkaline hydrogen evolution reaction. To afford a current density of 10 mA cm⁻², Ni-CeO₂/TM requires an overpotential as low as 67 mV, 77 mV lower than that of Ni/TM. Furthermore, the electrocatalyst shows good electrochemical durability with nearly 100% faradaic efficiency.
