Sažetak
Heterogeneous photocatalysis based on titanium dioxide (TiO2) is one widely used because of the extraordinary properties for degradation of organic matter under UV light irradiation, their low environmental impact, and cheapness. The major pitfalls in the practical application are the wide bandgap energy and quick recombination of the photogenerated electron-hole pairs. These limitations have very low efficiencies in the decomposition of effluent compounds under solar light. Sunlight irradiation has around 3-5% of UV light, and almost 45% is visible-light. To overcome these limitations, new photocatalysts based on the TiO2/reduced graphene oxide (rGO) nanocomposites are being designed. The rGO has been investigated because of its excellent properties. Thus, TiO2/rGO nanocomposites give us an interesting opportunity to design photocatalysts with extraordinary properties, which can shift photodegradation to the visible- light range of sunlight irradiation. The aims of this study are a synthesis of graphene oxide (GO), TiO2/rGO photocatalyst, and a comparison of the properties of the obtained materials with different characterization techniques and investigate the effect of various amounts of GO and synthesis parameters on the photoactivity. The achievement of these aims, i.e. the development of new TiO2/rGO nanomaterial with excellent photoactivity under sunlight irradiation would allow the wastewater treatment as environmentally friendly and lowcost photocatalyst methods.
