Graphene/TiO2 composite films for efficient photocatalytic degradation of antibiotics in wastewaters
Original language description
Graphene/oxide composite structures can be employed for advanced applications owing to their synergistic properties. We prepared mesoporous TiO2 layers including (i) graphene oxide and (ii) reduced graphene oxide at various concentrations. The films deposited on glass were tested for photocatalytic degradation, in water and under UV light, of sulfathiazole, a model compound of an eco-persistent antibiotic. The results show the high photocatalytic activity of the TiO2 layers. Moreover, a significant improvement in the photodegradation rate is found for graphene oxide with an optimum concentration of 2 wt. %. It is assigned to a favorable energy level combination that favors the photogenerated charge separation and increases the lifetime of the electron/hole pairs.
