ZIF-8 nanoparticles were produced with a molar ratio of Zn/2-methyl imidazole (Hmim)/H<sub>2</sub>O at 1/36/2206 by varying the flow rate of Zn precursor at 5, 10, 15, 20, and 25 mL/min into the Hmim solution. The physicochemical properties of the synthesized ZIF-8 nanoparticles were assessed using microscopy, analytical, and spectroscopy techniques. Owing to different flow rates of the precursor, variations in the ZIF-8 particles’ size and morphology were observed. It was found that the optimum flow rate was 15 mL/min (named Z-15), resulting in particle size of 261 nm, with a high specific surface area, thermal stability, and a substantially high yield of ∼89%. Furthermore, the dye adsorption studies, performed using Z-15 NPs, resulted in high methylene blue (∼82%) and methyl orange (∼76%) removal efficiency. The adsorption performance was maintained with dye-spiked simulated wastewater. The superior dye adsorption capacity of the ZIF-8 nanoparticles could be attributed to their microporous characteristics.

Here, a magnetic photocatalyst known as aluminum ferrite (AlFeO<sub>3</sub>) is employed to assess the degradation of SMZ and TC under visible light conditions. The structural and functional properties of co-precipitated AlFeO<sub>3</sub> with four different surfactants are examined. The little-known relevance of surfactant usage in AlFeO<sub>3</sub> synthesis, its characteristics, and its impact on emergent particle morphology for SMZ and TC degradation is reported. The results indicate that the catalyst can completely (100 %) degrade SMZ and TC in ∼60 mins. We propose a distinct degradation pathway for the same. Significantly, AlFeO<sub>3</sub> can decompose TC and SMZ to yield rather small compounds (<em>m/z</em> ∼ 60), thereby showing potential for practical use. Also, the use of different surfactants indicates that surface potential plays a significant role in photocatalytic degradation. Despite the large size and low surface area, AlFeO<sub>3</sub> performed well due to the surface potential of the catalyst. Findings suggest that using bulk catalysts with adjusted surface potentials offers sufficient performance, thereby bypassing the need for nano-sizing and concern about nano-toxicity. Further, the magnetic property of AlFeO<sub>3</sub> facilitates the recovery and reuse of the catalyst post-degradation.</div></div>","PeriodicalId":100290,"journal":{"name":"Colloids and Surfaces C: Environmental Aspects","volume":"2 ","pages":"Article 100049"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142577831","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}
