Investigation of photocatalytic activity of TiO<sub>2</sub>-GO nanocomposite

Abstract

Nanocomposite based on graphene oxide and TiO₂ was synthesized by hydrothermal method. The formation of nanocomposite was confirmed by Raman spectroscopy data. Characteristic peaks of graphene oxide and TiO₂ were recorded. Energy dispersive analysis showed the presence of titanium, carbon and oxygen in the nanocomposite. The specific surface area of TiO₂-GO nanocomposite is 1.16 times more than for pure TiO₂. A study of the photocatalytic activity of synthesized material in electrolytes with different pH was carried out. It is shown that the generation of photocurrent in TiO₂–GO depends on the electrolyte and increases by 2.9, 1.3 and 1.05 times in NaOH, KOH and Na₂SO₄, respectively, compared to the pure TiO₂ films.
