开发高效的富土电催化剂，在良好的条件下进行析氧反应，仍然是一个迫切和具有挑战性的问题。在这里，我们报道了以CoS2纳米阵列为前驱体，在碳布(Co-BiNA/CC)上电化学合成新型的Co-Bi纳米阵列。作为三维阳极，这种Co-BiNA/CC电极对OER表现出了良好的电催化性能，驱动10 mA cm-2的过电位要求为411 mV。值得注意的是，该电极还表现出出色的20h长期电化学寿命。
The development of efficient earth-abundant electrocatalysts for oxygen evolution reaction (OER) under benign conditions is still urgent and challenging. Herein, we report the electrochemical generation of novel Co–Bi nanoarray on carbon cloth (Co–Bi NA/CC) from CoS2nanoarray precursor. As a three-dimensional anode, such Co–Bi NA/CC exhibits excellent electrocatalytic performance for OER with the overpotential requirement of 411 mV to drive 10 mA cm–2. Notably, this electrode also demonstrates outstanding long-term electrochemical durability for 20 h.
