Photocatalytic degradation of methylene blue dye using dysprosium oxide/bismuth oxide nanocomposite

Kumar et al discuss their study on a facile synthesis of a novel nanocomposite and examined its photocatalytic activity by studying degradation of methylene blue dye under UV irradiation. Nano-catalyst was synthesised in situ wet chemical method and it was characterised by Scanning Electron Microscopy (SEM), Fluorescence spectroscopy, Energy-dispersive spectroscopy (EDS) and UV spectroscopy. Effects of degradation reaction parameters like initial dye concentration, photocatalyst load and pH of the effluent solution on the rate of degradation were studied. It was found that the removal of dye with the prepared catalyst was highest at alkaline pH.
