The dye degradation is a crucial area of concern for environmental research due to the extensive use of synthetic dyes in industries such as textiles and cosmetics. Dyes often exhibit high stability and resistance to conventional wastewater treatment. The harmful dyes block sunlight, disrupt photosynthesis, and deplete oxygen, thereby causing harmful effects on both human and aquatic organisms. Photocatalytic degradation driven by reactive oxygen species offers a sustainable solution by converting dyes into non-toxic by-products. In the present study, the synthesis of MgO nanoparticles using a Hog Plum leaf extract was carried out. The bio-synthesised nanoparticles were characterised using UV-Visible spectroscopy, Fourier Transform Infrared spectrophotometer, X-ray diffractometer, Scanning Electron Microscope and Energy Dispersive X-ray. The synthesised MgO nanoparticles were confirmed by UV-Visible spectroscopy. The nanoparticles exhibited good photocatalytic degradation, which was enhanced with the nanoparticles loading. The nanoparticles with 100mg loading showed 60% degradation. The degradation efficiency reduced with the increase in concentration of dye, and the optimum pH for maximum degradation efficiency was observed to be 12.
