- Abstract
In this study, 3-rGO nanocomposites were synthesized via a facile chemical method followed by a calcination process. The samples were characterized by UV-Vis spectroscopy, Fourier transform infrared (FT-IR) spectroscopy, Raman spectroscopy, BET technique, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results confirmed the formation of the nanocomposites. Photocatalytic activity of the synthesized samples was evaluated in degradation of 1-naphthol as a polycyclic aromatic pollutant under irradiation of xenon lamp. The concentration of the pollutant was measured by high performance liquid chromatography (HPLC). Efficient photocatalytic performance was observed and the kinetics data were well described by Langmuir-Hinshelwood model. WO3-rGO nanocomposites were obtained using a simple route via thermal reduction of graphene oxide sheets. Photocatalytic activity of the WO3/rGO nanocomposite was evaluated in degradation of 1-naphthol under visible irradiation. Reduced graphene sheets in the nanocomposite structure have a key role in photocatalytic performance of WO3-rGO nanocomposites due to their high absorption capacity and accepting electrons and preventing the recombination of electron-hole pairs in the semiconductor.
