Electrochemical water splitting could be an efficient alternative route for clean and renewable energy storage. However, widespread application of this technique is hindered by the high overpotential required for the sluggish anodic oxygen evolution reaction (OER). In this contribution, we report that novel N based conducting polymers exhibit excellent charge transfer properties with earth abundant transition metals. A strong interaction between Ni and N from polypyrrole (PPy) was identified via XPS, resulting in higher amounts of Ni^δ++ sites at the interface. Electronegative N from PPy shell, covering Ni₁₂P₅ microspheres, interacts with Ni on the inner edge and electrodeposited Co on the outer edge, establishing a dual synergic effect. This hybrid catalyst, with Co-N and Ni-N active interfaces, demonstrates faster OER kinetics owing to improved electrophilicity towards hydroxyl ions. With dual M-N sites, Co@Ni₁₂P₅/PPy displays a low Tafel slope of 40 mV/dec and stability up to 7 h of electrochemical cycling. This work enables discovery of a new class of anode materials based on metal-PPy analogs for alkaline OER.

电化学水分解可能是清洁和可再生能源存储的有效替代途径。但是，缓慢的阳极氧气析出反应（OER）所需的过高电势阻碍了该技术的广泛应用。在这项贡献中，我们报告了新型的基于N的导电聚合物与丰富的过渡金属表现出出色的电荷转移性能。通过XPS鉴定了来自聚吡咯（PPy）的Ni和N之间的强相互作用，从而导致界面处的^Niδ++位点数量增加。PPy外壳的负电N，覆盖Ni ₁₂ P ₅微球与内边缘的Ni相互作用以及外边缘的电沉积Co相互作用，产生双重协同效应。这种具有Co-N和Ni-N活性界面的杂化催化剂由于对羟基离子的亲电性提高，显示出更快的OER动力学。具有两个MN位点，Co @ Ni ₁₂ P ₅ / PPy显示出40 mV / dec的低Tafel斜率和长达7 h的电化学循环稳定性。这项工作使得能够发现基于金属PPy类似物的新型O阳极材料，用于碱性OER。
