SOLAR LIGHT INDUCED PHOTOCATALYTIC DEGRADATION OF MALACHITE GREEN USING BIVO4 CATALYST
Prafulla Kumar Panda, Debapriya Pradhan* and Suresh Kumar Dash
Abstract
A visible light active bismuth vanadate (BiVO4) nanoparticle was created using a simple, low-cost, and energy-efficient co-precipitation method.X-ray diffraction and Fourier-transform infrared spectroscopy were used to investigate the crystal structure, phase, and details of chemical bonds in the prepared BiVO4.The optical property of the catalyst, as well as a thorough evaluation of its morphology, was measured using ultraviolet-vis diffuse reflectance spectroscopy and FE-SEM analysis.The elemental composition and purity of the catalyst were determined using EDAX analysis.The degradation of MG under solar light radiation was used to scrutinise the photocatalytic efficiency of the catalyst. Within 75 minutes, BiVO4 demonstrated 95% degradation efficiency. To evaluate the degradation efficiency of the catalyst, various parameters (pH, concentration, dose, and time) are investigated
