Enhancing the stability of oxygen evolution reaction (OER) catalysts is a critical challenge for realizing efficient water splitting. In this work, we introduce an innovative approach by applying electric field during annealing CoFe2O4/C catalyst. By controlling strength (100 mV) and treatment duration (1 h), achieved dual optimization catalyst’s microstructure electronic environment, resulting in significant improvement catalytic stability. The experimental results demonstrate that field-treated catalyst exhibits reduced overpotential decay (only 0.8 enhanced (retaining 89.1% its initial activity after 24 h) extended OER testing. This performance significantly surpasses untreated sample, which showed 1.5 mV retained only 72.5% h. X-ray photoelectron spectroscopy (XPS) analysis confirmed promoted formation vacancies, substantially improved electron transfer efficiency, optimized local environment Co2+/Co3+ Fe2+/Fe3+, leading to decrease charge resistance (Rct) from 58.2 Ω 42.9 Ω. study not presents novel strategy modulating via fields but also broadens design concepts materials establishing structure–activity relationship between strength, microstructure, performance, ultimately providing theoretical foundation guidance development highly stable splitting catalysts.

Lithium-air batteries (LABs) are gaining attention as a promising energy storage solution. Their theoretical density of 3,505 Whkg −1 exceeds that conventional lithium-ion (500–800 ). The commercial viability and widespread adoption lithium-air face challenges such poor cycling stability, limited lifespan, unresolved side reactions. In this study, we synthesized spinel CoFe 2 O 4 -decorated on bio-based poly(2,5-benzimidazole) derived N-doped carbon for electrocatalysts. Notably, strong metal-substrate interaction (SMSI) was observed through various characterizations. bifunctional electrocatalytic activity stability toward oxygen reduction reaction evolution were significantly enhanced by the SMSI, LAB demonstrated high discharge capacity 18,356 mAhg at current 200 mAg , maintaining remarkable 1,000 even 400 cycles. bio-derived ABPBI holds promise practical air-breathing electrode high-capacity rechargeable LABs.

Lithium–sulfur batteries hold great promise as energy storage systems, but the shuttle effect of lithium polysulfides (LiPS) and large volume variation limit their capacity cycle life. We have developed CoFe alloy wrapped in N-doped porous carbon spheres (e-CF@NC) with a core–shell structure through simple copolymerization pyrolysis. The nitrogen-doped shell provides electron ion transport channels more active sites for electrolyte adsorption. high chemically stable can segregation polysulfides, further improving battery cycling stability. Besides, inside particles catalyze conversion between LiPS Li2S, speeding up reaction kinetics reducing solvation sites. Consequently, lithium–sulfur e-CF@NC-2 cathode display initial specific 1146 mA h g−1 at 0.1 C, excellent rate performance (891 1 741 2 C), satisfied stability (average decay 0.033% per C 300 cycles), demonstrating significant application potential.
