Synthesis of TiO2/GO nanocomposite for Methylene Blue Degradation

Abstract

In using visible light for commercially available photocatalytic TiO2 powder, the alteration of its chemical structure is required in which a metal or non metal ion is introduced to the naturally TiO2 compound in a process called doping. In this study, a graphene oxide is chosen as composite that can be functioned under visible light irradiation since it can extended light absorption range and can improved activity of TiO2/GO nanocomposite for enhancing charge separation. The TiO2/GO nanocomposite were characterized by SEM, TEM, XRD, and FT-IR. The TiO2/GO nanocomposites was active for reduction of Methylene Blue in aqueous media.
