摘要

本研究报道了二茂铁取代的镍（II）卟啉（2.1.2.1）配合物的合成、表征、结构及析氧反应（OER）性能。用两个二茂铁单元功能化的Ni-3配合物表现出优异的OER活性，在碱性介质中在10 mA cm-2下达到280 mV的过电位。这种增强归因于富含电子的二茂铁基团，它们在催化过程中充当有效的电子转移介质。DFT计算证实了这些发现，揭示了双二茂铁取代催化剂的理论过电位为0.79 eV。这些结果强调了二茂铁在降低分子OER催化剂过电位中的关键作用。

Ferrocene Units Substitution in Nickel(II) Porphyrin(2.1.2.1) Induce Extremely Low Oxygen Evolution Reaction Overpotential

This study reports the synthesis, characterization, structure and The oxygen evolution reaction (OER) performance of ferrocene-substituted nickel(II) porphyrin(2.1.2.1) complexes. The Ni-3 complex, functionalized with two ferrocene units, demonstrates exceptional OER activity, achieving an overpotential of 280 mV at 10 mA cm-2 in alkaline media. This enhancement is ascribed to the electron-rich ferrocene moieties, which act as efficient electron-transfer mediators during catalysis. DFT calculations corroborate these findings, revealing a theoretical overpotential of 0.79 eV for the dual-ferrocene-substituted catalyst. These results underscore the critical role of ferrocene in lowering the overpotential of molecular OER catalysts.
