What is Mixed phase lamellar titania-titanate anchored with Ag2O and polypyrrole for enhanced adsorption and photocatalytic activity about?
Ag2O/TiO2/polypyrrole composite was synthesized by stepwise modification of the rutile TiO2 though hydrothermal alkaline treatment to obtain mixed phase sodium titanate/titania (Na-TiO2) followed ion-exchange replacement of Na(+) by Ag(+) to get Ag2O/TiO2 (through precipitation) and H2O2 oxidative polymerization of pyrrole onto Ag2O/TiO2 to get final composite Ag2O/TiO2/polypyrrole (Ag2O/TiO2/PPY). Composite materials were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Field emission scanning electron microscopy (FE-SEM), Fourier transform infrared spectroscopy (FTIR), Diffuse reflectance ultraviolet-visible spectroscopy (UV-vis DRS) and Raman analysis. The synthesized materials showed increase in the optical property, adsorption and photocatalytic scavenging of the methylene blue (MB). The adsorption capacity of MB onto the prepared materials was observed in the following order: TiO2
