Preparation of PANI Modified ZnO Composites via Different Methods: Structural, Morphological and Photocatalytic Properties

Polyaniline modified zinc oxide (PANI-ZnO) photocatalyst composites were synthesized by focusing on dissolution disadvantage of ZnO. In-Situ chemical oxidation polymerization method was performed under neutral conditions (PANI-ES) whereas in hybridization physical blending applied using emeraldine base polyaniline (PANI-EB). PANI-ZnO prepared various ratios aniline (ANI) to ZnO as 1%, 3%, 6% and 9%. The alterations the structural morphological properties compared Fourier Transform Infrared (FT-IR), Raman Spectroscopy, X-ray Diffraction (XRD) Scanning Electron Microscopy-Energy Dispersive Analysis Unit (SEM-EDAX) techniques. FT-IR spectroscopy confirmed presence PANI all composites. SEM images revealed differences based preparation methods. Photocatalytic performances specimens investigated following degradation methylene blue (MB) aqueous medium UVA irradiation. effects catalyst dose initial dye concentration also studied. MB followed both decolorization extents removal aromatic fractions. expressed enhanced photocatalytic performance (~95% for methods) sole (~87%). found be more efficient than emphasizing significance medium.
