In situ growth of NiTe nanosheet film on nickel foam as electrocatalyst for oxygen evolution reaction

Developing effective and low-cost oxygen evolution reaction (OER) electrocatalysts based on earth-abundant elements is vital for future clean and regenerated energy systems. In this work, one-step growth of NiTe nanosheet film on nickel foam (NiTe/NF) via a facile tellurization treatment of NF has been demonstrated. This NiTe/NF electrode exhibits remarkable OER activity with overpotential requirement as low as 262 mV to deliver an anodic current density of 10 mA cm −2 , as well as superior durability in alkaline solution. This work provides an attractive earth-abundant 3D catalyst electrode for OER in overall water splitting.
