However, zinc anodes, exhibit insufficient cycle life and low utilization in aqueous electrolytes, mainly owing to shape change and passivation. While nanostructuring of Zn anodes has been explored for Zn-Ni rechargeable alkaline batteries, no explicit electrochemical studies have elucidated how nanostructures, fabricated in the oxidized state, are reduced during the initial formation step, yielding elemental Zn. In this work, a hydrothermal synthesis of freestanding electrodes is proposed, based on vertically aligned ZnO nanorods grown directly on carbon cloth (CC) (ZnO/CC). ZnO nanostructuring mitigates passivation, while the carbon cloth fiber network confines soluble Zn(II) intermediates, hindering diffusion into the electrolyte bulk. Moreover, the CC substrate provides optimal electronic contact to the active material, and acts as a built-in current collector. This work investigates the evolution of ZnO/CC during the first electrochemical reduction cycle, with emphasis on morphochemical nanostructure changes rather than establishing a benchmark anode. Electrochemical measurements are combined with advanced characterization techniques, high-resolution transmission electron microscopy (HRTEM), and X-ray absorption hyperspectral imaging via scanning transmission X-ray microscopy (STXM) and ptychography at the Zn L-edge. This multimodal approach offers unprecedented insights into the ZnO-to-Zn reduction to guide future Zn-ion anode design.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"9 6","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsu.202400921","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144367545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, ruthenium (Ru)-based electrocatalysts have received a lot of attention because their activity is better than that of commercial catalysts and their price is more affordable, showing great potential in acidic OER and alkaline HER. However, there are still obstacles for Ru-based electrocatalysts in practical applications of industrial water electrolyzers, and regulatory strategies need to be developed to further optimize its performance. Herein, a comprehensive review is presented concerning it. First, its fundamental principles that focus the basic content of industrial water electrolyzers and the application potential of Ru-based electrocatalysts are discussed.

Activated biocarbon derived from sugarcane bagasse (SB-C) is used as a supporting substrate with Molybdenum diselenide (MoSe2) to design the heterostructure photocatalyst to improve charge separation and interface charge transfer. Compared to individual MoSe2, synthesized from different techniques, and SB-C components, the SB-C/MoSe2 heterojunctions demonstrated a significantly enhanced ability to degrade different organic pollutants (including different organic dyes, organic solvent, and heavy metal) under visible light irradiation, achieving the best rate of 97.17% under 20 min of visible light irradiation for degrading methylene blue dye (MB), and organic solvent viz.

This work offers a simple and scalable method for the preparation of manganese ferrite with varying deposition times using chemical bath deposition (CBD). Varying deposition time results in a transformation from the manganese ferrite hydrate (MnFe2O4.H2O) to manganese ferrite (MnFe2O4) cubic structure and alteration in morphology from tetrahedral crystals to octahedral-like in MnFe2O4 series thin films (C-MFO).
