The findings reveal that CLQ exhibits a concentration-dependent inhibition efficiency, reaching over 91 % at 1 g/L and 25°C. Notably, the inhibition performance slightly increases with temperature, attributed to enhanced molecular mobility and diffusion of CLQ, which facilitate improved surface coverage and the filling of surface imperfections, thereby strengthening the protective barrier on the steel. PDP analysis implies that CLQ behaves as a mixed-type inhibitor. Surface analyses, including SEM, EDS, 3D profilometry, and FTIR, conducted after a 24-h immersion period substantiate the development of a protective layer on the steel surface. Computational studies highlight that the aromatic heterocyclic and aliphatic amine regions of CLQ are pivotal in facilitating electron transfer during adsorption, as evidenced by analyses of the HOMO, LUMO, & molecular electrostatic potential (MEP). These analyses support a mixed physisorption and chemisorption mechanism, with the aromatic moiety identified as the primary adsorption site. The coherence between experimental and computational results underscores CLQ's effectiveness as a corrosion inhibitor. Moreover, the utilization of expired chloroquine not only offers a cost-effective solution but also promotes environmental sustainability by repurposing pharmaceutical waste, thereby reducing pollution.</div></div>","PeriodicalId":101196,"journal":{"name":"Sustainable Chemistry for the Environment","volume":"10 ","pages":"Article 100251"},"PeriodicalIF":0.0,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143855306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, Fe-Ni/AC catalysts were synthesized with different metal loading via wet impregnation method and characterized using FT-IR, SEM-EDX, TGA, BET and NH<sub>3</sub>-TPD. The catalysts were subjected to an acetylation reaction under a microwave assisted condition at 90 ℃ for 60 min and the performance was demonstrated based on glycerol conversion and the production of acetins, specifically monoacetin (MA) and the combined yield of diacetin and triacetin (DA+TA). From the characterization results, the impregnated iron-nickel significantly impacts the physicochemical properties of the studied bimetallic catalyst.
