photocatalytic activity of polyaniline/ zno nanoparticles composite under visible light irradiation

nanostructured ZnO/PANcomposite was synthesized by in situ polymerization of aniline monomers in the presence of ZnO Nanoparticles . Ananostructured ZnO/PAN composite was used as phtocatalyst for degradation of methylene blue dye. XRD and UV-Vis techniques were used to characterize the nanocomposite structure . UV-Vis spectrum of PAN/ZnO composite shows a red shift from 440 nm in pristine PAN to 455 nm in nanocomposite that might occur due to the interation between PAN chains and ZnO nanoparticles and cause composite to show better photocatalytic activity under visible light.
