Comparative Organics Remediation Properties of Nanostructured Graphene Doped Titanium Oxide and Graphene Doped Zinc Oxide Photocatalysts

Abstract

In recent years, we have accomplished effective organics remediation using titanium oxide (TiO 2 ) doped transition metals, zinc oxide (ZnO) nanowires and silver & palladium doped ZnO nanowires. The present manuscript displays the advantage of organic remediation in both UV and visible radiation using graphene (G) doped TiO 2 nanoparticles, G doped ZnO nanowires. The nanostructured G-TiO 2 nanoparticles and G-ZnO nanowires were synthesized using sol-gel and hydrothermal methods. The nanostructured materials were characterized using scanning electron microscopy (SEM) and X-Ray diffraction (XRD), procedures. The remediation of organic compounds (naphthalene, methyl orange) in water was achieved under both UV and visible radiation using graphene doped nanostructured photocatalytic materials. The advantage of graphene doped ZnO nanowires as well as G-TiO 2 nanoparticles has revealed organics remediation in both UV and visible radiation of light.
