Development of Photocatalytic Nanocomposite Based on Titanium Dioxide and Reduced Graphene Oxide

In recent decades, due to the growth of the industries, the aquatic ecosystem is contaminated by pollutants including harmful and persistent dyes. The usage of dyes agents in many industries leads to a global problem because of their non-degradable properties. Since conventional water treatment plants are usually unproductive in removal dyes from effluents, more efficient technologies, advanced oxidation processes (AOPs) as well as heterogeneous photocatalysis based on TiO2, are used. The major drawbacks of TiO2 photocatalyst are fast recombination of photogenerated electron-hole pairs, which leads to the lower photocatalytic activity (limited activity in the visible light range) under solar irradiation. Hence, modification of TiO2 photocatalyst with materials such as non-metals, metals, or graphene-based materials like reduced graphene oxide (rGO) is commonly an the approach that has been used to overcome their limitations. To use a visible range of the solar spectrum and efficient removal of organic compounds, it is necessary to produce competent TiO2/rGO nanocomposites for the degradation of dyes from an aqueous medium.
