Abstract
Increasing concerns on water pollution encourage to investigate new techniques for controlling associated problems with practical and sustainable approaches. Heterogeneous photocatalysis is reported as the green, sustainable and clean process by using metal oxide semiconductors in removing dyes, medicines and insecticides from water. In this study deposition of nano sized Bismuth oxide (Bi2O3 NPs) thin film on sintered silica discs(30mm dia) was achieved by spray pyrolysis technique, by spraying crystal clear solution (containing Bismuth Acetate (CH3CO2)3Bi dissolved in 1 Molar CH3COOH) onto the sintered silica substrate kept at 450 °C. Deposited disc were characterized by Field emission scanning electron microscopy (FESEM), X-ray Diffraction (XRD) for evaluation of obtained crystallinity and phases, diffused reflectance spectroscopy (DRS) to determine energy band gap possessed by films. Photocatalysis was performed under visible light to analyse the photocatalytic activity of deposited thin films.
