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.
