Publication date: Available online 30 May 2019Source: Journal of Materials Research and TechnologyAuthor(s): Muhammad Yousaf Khan, Manzoor Ahmad, Sana Sadaf, Saleem Iqbal, Faisal Nawaz, Javed IqbalAbstractTo enhance the applications of tungsten trioxide in terms of photocatalytic activity novel graphene based nanocomposites (indigo-RGO/WO3) were fabricated through hydrothermal method which shows efficient photocatalytic activity. Scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), X-ray powder diffraction (XRD) and UV–Vis spectroscopy were carried out to characterize the prepared nanocomposite. Photocatalytic activity of synthesized composite was carried out at different catalyst concentration and pH. Maximum activity is exhibited at pH 11.0 with 30 mg of catalyst.
