In particular, upcycling Nickel (Ni) ions into electrocatalytic material has been proven a feasible route, but the current methods are still restricted by the complicated, environmentally-aggressive operation. Herein, we propose a low-cost, 3D-structured adsorbent, constructed by in-situ growing ZIF-8 on network-structured bacterial cellulose, for efficient Ni capture. It exhibits superior stability and 7.3-times higher Ni adsorption kinetics than the ZIF-8 alone. Importantly, the Ni-enriched adsorbent, after treatment of Ni-containing electroplating wastewater, could be pyrolytically converted into an efficient self-supported electrocatalyst for oxygen evolution reaction (OER), showing comparable OER activity to the state-of-the-art Ni-based electrode. This work provides a sustainable, facile route for Ni upcycling into self-supported electrode, which may be extended to recovery of various valuable metals from waste streams.</p></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":null,"pages":null},"PeriodicalIF":11.2,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142148751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
