The Polyaniline Supported CdS/CeO2/Ag3PO4 Nanocomposite: Synthesis, Characterization and Photocatalytic Activity for Methyl Orange Dye Degradation

Abstract

Tigabu Bekele

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.
