ABSTRACT: The petroleum
compounds were photocatalytically remediated from water using graphene (G)- titanium
oxide (TiO2) nanocomposite material in visible light radiation. The
G-TiO2 nanocomposite was synthesized using sol-gel technique, and
its structural & morphological properties were studied using scanning
electron microscopy (SEM), X-ray diffraction (XRD), transmission electron
microscopy (TEM), particle analyzer and UV-Visible spectroscopy (UV-Vis)
measurement techniques. Various petroleum-based chemicals (toluene, naphthalene
and diesel) were remediated, and samples were analyzed using optical and gas
chromatography (GC) techniques. The mechanism of photocatalytic remediation of
petroleum compounds using G-TiO2 nanomaterials is understood and
well compared with data available in literature.
