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.

基于未来的清洁和可再生能源系统，开发基于地球丰富元素的有效且低成本的氧气析出反应（OER）电催化剂至关重要。在这项工作中，已经证明了通过便捷的NF碲化处理，可以在泡沫镍（NiTe / NF）上一步一步生长NiTe纳米片薄膜。该NiTe / NF电极具有卓越的OER活性，低电势要求低至262 mV，以提供10 mA cm ^-2的阳极电流密度，并在碱性溶液中具有出色的耐久性。这项工作为整个水分解过程中的OER提供了一种有吸引力的地球丰富的3D催化剂电极。
