However, achieving this balance remains a formidable challenge, primarily due to the requirement of robust, earth-abundant reversible oxygen electrocatalyst. The present study introduces a simple strategy to synthesize Co-Nx rich nanoalloy with N-doped porous carbon tubes (NiCo@NPCTs). The optimized catalyst is bestowed with high electrochemical surface area, and three dimensional (3D) interwoven N-doped PCTs. Moreover, the presence of dual redox-active sites synergistically promotes rapid mass/charge transfer for oxygen electrocatalysis. These features offer excellent reversibility for oxygen electrocatalysis with a reversible oxygen potential gap (ΔE) of 0.74 V. The NiCo@NPCTs is utilized as an air-electrode for designing ZABs and using the same electrode-material asymmetric supercapacitor device (ASC) is fabricated. The assembled ZAB delivers an impressive peak power density of 298 mW cm-2 and specific capacity of 731mAh g-1 at 50 mA cm-2, along with high rate-capability, durable round-trip voltaic-efficiency. The as-fabricated ASC also shows exciting performance with negligible fading in capacitance and columbic efficiency after 10,000 continuous charge-discharge cycles at a 10 A/g current density. In addition, ZAB-ASC integrated device is assembled, showing real-time application. Thus, the synthesized electrode-material holds great promise for electrocatalysis and also for diverse energy storage applications.","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"683 Pt 1","pages":"818-832"},"PeriodicalIF":9.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142870893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our findings indicate that the incorporation of AMR into NaOH electrolyte offers an effective strategy for preventing the self-corrosion of the Al anode, leading to significant enhancements in battery performance. Electrochemical experiments demonstrate that AMR achieves an inhibition efficiency of 53.9%. Through in-situ optical microscopy and in-situ attenuated total reflection Fourier-transform infrared spectroscopy, it is observed that the introduction of AMR can retard pitting corrosion by adsorbing onto the Al surface. This leads to a significant increase in specific capacity, from 1096 to 1667 mAh g-1, compared with the electrolyte without AMR for AABs. Further analysis utilizing X-ray photoelectron spectroscopy, quantum chemical calculations, and ab-initio molecular dynamics determine that 4-hydroxycinnamamide (4-HCAA) and flavone molecules, which are the most active components of AMR, can bind with Al atoms through the carbonyl O functional group, forming an O-Al-O bond, thus suppressing the self-corrosion of the Al anode.
