Year: 2024
Type: article
Abstract: This study is an attempt to investigate the photocatalytic performance of magnesium (Mg) doped SnO2 nanoparticles (NPs) for the degradation of Crystal Violet (CV) dye under sunlight irradiation. Mg doped SnO2 NPs with varying concentrations of Mg were synthesized through coprecipitation method. The synthesized NPs were characterized using X-ray diffraction (XRD), UV-Vis spectroscopy and Fourier transform infrared (FTIR) spectroscopy to confirm their structural and optical properties. The photocatalytic efficiency of Mg-doped SnO2 NPs was evaluated by examining the degradation rate of CV dye. The results demonstrated that Mg doping significantly improved the photocatalytic activity of SnO2 NPs, with a 15wt% Mg doping concentration leading to the highest degradation rate of CV dye. The enhanced photocatalytic performance is attributed to the increased charge carrier separation due to Mg doping. This study highlights the potential of Mg-doped SnO2 NPs as effective photocatalysts for the degradation of organic pollutants, offering a promising approach for wastewater treatment applications.
