Abstract
In the present work, different types of photocatalysts in single, binary and ternary systems with different molar ratios (1:1, 2:1, 3:1 and 4:1) of CdS: CeO2 /Ag3PO4 was synthesized by co- precipitation method. Polyaniline supported CdS/CeO2/Ag3PO4 nanocomposite was also synthesized by “in situ” chemical oxidative method. Crystal structure, surface area, morphology, band gap energy, functional groups, optical properties and electron transfer of the as-synthesized photocatalysts were characterized by using XRD, BET, SEM-EDX, UV/Vis, FTIR, PL and EIS instruments, respectively. Photocatalytic activities of single, binary, bare and supported ternary nanocomposite were evaluated by using aqueous solution of model pollutant methyl orange dye (MeO) as well as a real sewage sample solution collected from Bahirdar Textile Share Company.
