Enhanced Photocatalytic Activity of Hybrid rGO@TiO2/CN Nanocomposite for Organic Pollutant Degradation under Solar Light Irradiation

The three-component hybrid (rGO/TiO2/CN) nanocomposite was prepared in order to enhance the photocatalytic properties of anatase TiO2 nanoparticles (NPs) under solar-like irradiation. rGO/TiO2/CN a mixture reduced graphene oxide (rGO, 8 wt%), (NPs), and graphitic carbon nitride (g-C3N4, 16 wt%). It self-assembled through one-step hydrothermal method, followed by an annealing process. photocatalyst thoroughly characterized means X-ray diffraction (XRD), photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR), scanning electron microscopy (SEM), transmission (TEM), Brunauer-Emmett-Teller (BET) nitrogen adsorption/desorption technique UV-Vis diffuse reflectance (DRS). activity TiO2, TiO2/rGO, TiO2/CN studied degradation rhodamine B (RhB) aqueous solution results showed that highest achieved mixture, which can be attributed synergistic effect incorporation both rGO g-C3N4 with TiO2. Further, influence pH value RhB dye different water matrix (Milli-Q, tap, alkaline water) on efficiency examined. In addition, recycle test performed for rGO@TiO2/CN investigate effectiveness photodegradation three successive cycles. conducted indicate matrices play important role rate.
