Metal-organic frameworks (MOFs), known for their abundant active sites and unique porous structures, exhibit significant promise in addressing uranium-related challenges. In this study, a nano-hierarchical porous structure of Cu-BTC (NH-Cu-BTC) was synthesized at room temperature and atmospheric pressure, utilizing <em>N,N</em>-dimethylethylenediamine as a templating agent in the aqueous phase. The impact of activation on the porosity characteristics of NH-Cu-BTC was investigated. The as-synthesized NH-Cu-BTC possessed micropores, mesopores, and macropores, with crystal sizes approximately 150 nm. Through simulation calculations, the electrostatic potential and orbital energies of the templating agent molecule were analyzed to elucidate the synthesis mechanism. Various factors influencing the adsorption of uranium (VI) by NH-Cu-BTC, including pH, contact time, and temperature, were explored, and the underlying adsorption mechanisms were elaborated. Compared to C-Cu-BTC, NH-Cu-BTC exhibited a 32.8 % enhancement in its adsorption capacity for uranium (VI). This investigation furnishes precious comprehension regarding the fabrication and utilization of porous substances, proffering a novel tactic for proficiently eliminating uranium (VI) from aqueous mediums.</div></div>","PeriodicalId":13599,"journal":{"name":"Inorganica Chimica Acta","volume":"581 ","pages":"Article 122623"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143551757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
