Influence of graphene oxide on photocatalytic properties of titan (IV) oxide
Pollution of the environment, especially on water causes increasing pressure on mankind. The use of pharmaceuticals, cleaning agents and pesticides appears to have caused the emergence of new types of pollution in the environment, called micropollutant. Micropollutant cause major changes in plants and animals living in the aquatic environment. One of the processes that cause the total degradation of this type of pollution is photocatalysis. For the process of photocatalysis photocatalyst such as titanium (IV) dioxide (TiO2) is required. The efficiency of using TiO2 on a daily sun light is limited due to the high energy banned zone (3-3.2 eV). One of the methods showing the potential is the use of graphene oxide (GO). In this paper a TiO2 / GO composites with various concentrations of GO were prepared. The concentrations of GO ranged from 5, 10 and 25 wt. % GO relative to the mass of TiO2. It was observed that the concentration of GO affects the photocatalytic activity of the obtained composite. Photocatalytic activity was followed by a degradation of salicylic acid in prepared modal solution, in a pilot reactor followed by UV-ViS spectrometry. The prepared catalysts were characterized by scanning electron microscopy (SEM) equipped with an energy dispersive X-ray spectroscopy (EDX).
