摘要

利用分子间协同作用，在泡沫镍（NF）上合成了高效析氧反应（OER）催化剂（FeOOH@CoFeOS/NF）。优化后的FeOOH@CoFeOS/NF催化剂具有良好的碱性OER性能，在10 mA cm−2 (η10)（25°C）下的过电位为212 mV，塔菲尔斜率为62.8 mV dec−1。值得注意的是，FeOOH@CoFeOS/NF在1.0 M KOH中保持了38 h的稳定性，所取得的结果超过了大多数过渡金属氧化物硫化物催化剂。本研究为利用分子间协同效应和开发高性能OER电催化剂提供了有价值的方法。

Surface-reconstructed FeOOH@CoFeOS/NF architectures: leveraging nano-layered stacking for accelerated oxygen evolution kinetics†

A high-efficiency oxygen-evolution reaction (OER) catalyst (FeOOH@CoFeOS/NF) was synthesized on nickel foam (NF), utilizing an intermolecular synergistic effect. The optimized FeOOH@CoFeOS/NF catalyst demonstrated outstanding alkaline OER performance, exhibiting a low overpotential of 212 mV at 10 mA cm⁻² (η10) (25 °C), along with a small Tafel slope of 62.8 mV dec⁻¹. Notably, FeOOH@CoFeOS/NF maintained its stability in 1.0 M KOH for 38 h. The achieved results surpassed those of the majority of transition metal oxide sulfide catalysts. This research contributes a valuable methodology for leveraging intermolecular cooperative effects and the development of high-performance OER electrocatalysts.
