TY - JOUR TI - Investigation of the effect of PAn and PAn/ZnO photocatalysts on 100% degradation of Congo red under UV visible light irradiation and lightless environment AB - PAn (polyaniline) and PAn/ZnO photocatalysts were synthesized using chemical polymerization of aniline.The structure characterization of the synthesized samples was analysed by using X-ray diffraction (XRD), Fouriertransform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM),and UV-Vis spectroscopy measurements, and thermal gravimetric analysis (TGA). The photocatalytic activities of PAnand PAn/ZnO (0.1g/100ml) on the degradation of the Congo red (CR) dye were studied under the UV visible lightirradiation and the lightless environment and the efficiency of catalysts have been explained in details. Contribution ofUV visible light irradiation on the 100% degradation of CR dye for the PAn and PAn/ZnO photocatalyst is determined.The reaction kinetics and effect of pH (pH 4 and pH 10) were investigated by using first order kinetic model. Accordingto the experimental results, photocatalytic reaction rate of Congo Red increased in acidic environment and under UVvisible light irradiation.
