Photoelectric properties of a nanocomposite derived from reduced raphene oxide and tio2

Abstract

The properties of a nanocomposite derived from reduced graphene oxide and TiO2 obtained by hydrothermal synthesis were investigated. Nanocomposite formation was confirmed by SEM as well as Raman and IR spectroscopy. The introduction of 10% rGO into the nanocomposite leads to considerably lower resistance than found for TiO2 itself. The combination of enhanced electrotransport, optical, and adsorption parameters of these nanocomposites leads to better photoelectrochemical characteristics than for pure titanium dioxide.
