Nevertheless, the practical implementation of cellulose-based materials is limited by their intrinsically low ionic conductivity. Herein, we introduce a novel zincophilic artificial protective layer by strategically hybridizing hydroxypropyl cellulose (HPC) with zinc trifluoromethanesulfonate on a zinc metal anode (HZ@Zn). Characterization and calculations demonstrate that the multi-hydroxyl architecture of HPC constructs hydrogen bond networks, whereas the Zn2+-coordinated HPC domains function as preferential nucleation sites for zinc deposition. These interactions collectively enhance ion transport and accelerate desolvation kinetics. Additionally, the hybrid layer's mechanical flexibility and interfacial adhesion ensure the integrity of the artificial protective layer during long cycling. Thanks to this synergistic effect, HZ@Zn shows exceptional electrochemical performance, including a low desolvation activation energy of 14.38 kJ mol−1 and ultra-long cycling stability. Symmetric cells demonstrate exceptional longevity, exceeding 9,500 h at 0.5 mA cm−2/0.25 mAh cm−2, whereas HZ@Zn‖PANI full cells maintain 89.8% capacity retention after 4000 cycles at 5 A g−1.

However, facilitating the deep reconstruction of electrocatalysts to form active species remains a significant challenge. Here, a simple two-step method composed of impregnation and carbonization process is proposed to synthesize N, S co-doped microcrystalline cellulose-derived carbon-supported nickel sulfide (Ni3S2) nanoparticles. The in situ Raman reveals that Fe substitution promotes the reconstruction of Ni3S2, accompanied by the cleavage of the Ni–S bond, leading to the deep reconstruction into (Ni,Fe)OOH (DR-(Ni,Fe)OOH) during the OER. Moreover, density functional theory calculations reveal that Fe substitution induces a downshift in the energy band structure, which lowers the energy barriers and thereby improves the kinetics of the OER. The generated DR-(Ni,Fe)OOH delivers a relatively low overpotential of 260 mV and superior durability for 50 h under OER condition. The ZAB incorporating DR-(Ni,Fe)OOH + Pt/C as the air cathode demonstrates superior efficiency and durability, achieving a peak power density of 188.3 mW cm−2, a specific capacity of 811.1 mAh g−1, and long-term stability exceeding 200 h.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"8 2","pages":""},"PeriodicalIF":24.2,"publicationDate":"2026-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.70136","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147562103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combing in situ Raman spectroscopy, 18O isotopic labeling, and electrochemical analysis, we demonstrate that the oxygen evolution reaction follows a lattice oxygen-mediated mechanism. The CrOx layer selectively adsorbs hydroxide ions, forming a dynamic interfacial barrier that electrostatically repels Cl− ingress, thereby mitigating Cl- corrosion.
