摘要
本研究成功制备了一种旋光性铁(II)-三吡啶配合物（Fe-pt），并用不同的物理化学方法对其进行了表征。通过将Fe-pt固定在泡沫镍电极上，考察了Fe-pt对析氧反应的电催化性能。该体系在10 mA cm - 2下的过电位为~ 270 mV，在碱性条件下表现出良好的催化效率。循环伏安法（CV）和时电位法证实了其良好的稳定性和OER活性。结构和光谱分析表明，泡沫镍基板增强了电子传递，提供了强大的支撑，进一步提高了催化性能。此外，在催化过程中，理论预测和实验得到的结构和光谱变化之间存在很强的相关性。本研究强调了单核Fe-pt配合物作为OER应用的耐用电催化剂的潜力。图形抽象
Iron(II)-Terpyridine Complex as a Single-Atom Electrocatalyst for Enhanced Oxygen Electrocatalysis: Experimental and Theoretical Insights
In this study, an optically active iron(II)-terpyridine complex (Fe-pt) has been successfully prepared and characterized by different physicochemical methods. Its electrocatalytic performance for the oxygen evolution reaction (OER) was assessed by immobilizing Fe-pt onto Ni-foam electrodes. The system exhibited an overpotential of ~ 270 mV at 10 mA cm⁻2, demonstrating excellent catalytic efficiency under alkaline conditions. Cyclic voltammetry (CV) and chronopotentiometry, confirmed its remarkable stability and OER activity. Structural and spectroscopic analyses revealed that the Ni-foam substrate enhances electron transport and provides robust support, further boosting the catalytic performance. Additionally a strong correlation could be observed between theoretical predictions and experimentally obtained structural and spectral changes during the catalytic process. This study highlights the potential of mononuclear Fe-pt complex as durable electrocatalyst for OER applications.
