Efficient Photocatalytic Degradation of Congo Red Dye Using Facilely Synthesized and Characterized MgAl₂O₄ Nanoparticles

ACS Omega, Год журнала: 2024, Номер 9(4), С. 4870 - 4880

Опубликована: Янв. 19, 2024

The discharge of congo red dye into water sources by factories has been associated with a range health concerns, such as cancer, redness, skin irritation, and allergic reactions. As result, this research focused on the cost-effective straightforward production MgAl2O4 nanoparticles using Pechini sol–gel process. Subsequently, these were employed for successful photocatalytic decomposition dye. Moreover, extensive characterization fabricated was conducted through diverse methodologies, which included Fourier-transform infrared spectroscopy, ultraviolet–visible spectrophotometry, high-resolution transmission electron microscopy (HR-TEM), field-emission scanning (FE-SEM), powder X-ray diffraction (XRD). Furthermore, XRD analysis disclosed that average crystal size produced is 10.36 nm, their optical energy gap determined to be 3.71 eV. FE-SEM examination unveiled combination spherical disorganized structures 0.14 μm grain size. HR-TEM analysis, in turn, revealed composed minuscule particles an diameter 8.75 nm. maximum degradation 50 mL at concentration 25 mg/L reached 99.27% within 80 min pH 3. Additionally, findings confirmed consistent activity toward even after four cycles, thereby validating effectiveness reusability developed study.

ChemistrySelect, Год журнала: 2025, Номер 10(6)

Опубликована: Фев. 1, 2025

Abstract The global shortage of fresh water is a critical issue, especially in regions with limited rainfall. Developing reliable and wastewater treatment technologies urgent. Among the available methods, adsorption stands out as highly effective, straightforward, cost‐efficient approach. It avoids use additional chemicals reduces risk contaminating source undesirable by‐products. Chitosan (CS)‐based hydrogels have gained attention for their excellent capacities pollutants water. These materials are also known bioavailability, biocompatibility, biodegradability, cost‐effectiveness, environmental friendliness, making them promising candidates treatment. This comprehensive review explores recent advancements CS‐based various applications, including pollutant removal, oil‐water separation, seawater desalination, atmospheric condensation. highlights benefits this material treatment, providing broader understanding potential research community. focuses on synthesis modification techniques these hydrogels, such cross‐linking, grafting, ion imprinting, which significantly enhance performance mechanical stability. Additionally, challenges faced by practical applications discussed, along solutions. paper concludes forecasting future directions field, offering valuable insights researchers. Overall, provides overview current state art into effective utilization emphasizing to address pollution challenges.
