Dye, a major global pollutant causing environmental and health issues, can be effectively degraded through photocatalysis. This study synthesised bismuth oxychloride (BiOCl) nano-photocatalyst via hydrolysis characterized it using various analytical instruments. The UV-Vis absorbance of the displayed peaks at 211 nm, 361 688 with band gap 3.0 eV, conduction minimum 1.97 valence maximum 4.97 eV. dynamic light scattering showed 3349 nm 660 while BiOCl had zeta potential -17.3 mV conductivity 0.245 mS/cm. X-ray diffraction exhibited four sharp intensity 11.95º, 25.81º, 32.50º, 33.40º, average crystallite size was 43.39 scanning electron microscope plate-like morphology. achieved 88.21% degradation methyl green within 60 minutes under LED irradiation pH 7.5 dye concentration 6×10−6 mol/L. photocatalytic performance, driven by hydroxyl (•OH) superoxide (O2•−) radicals, 96.55% mineralization as confirmed COD analysis. These findings emphasize for effective sustainable wastewater remediation visible conditions.
