چکیده :

Graphene oxide (GO) based nanomaterials have received a lot of attention in nanotechnology, mainly because of their unique nature, including high surface area, excellent electrical and thermal conductivity, and high optical transmission [1]. Graphite carbon nitride (g-C3N4) has also attracted much attention because of its application in photocatalysis. As a possible alternative to TiO2, metal-free g-C3N4 can be operated directly with visible light due to the corresponding band gap of 2.7 eV. However, the photocatalytic properties of g-C3N4 are still limited due to its low surface area and high recombination rate of photoinduced electron-hole pairs [2]. In this study, g-C3N4 modified with Go (g-C3N4/Go) was prepared as a novel nanocomposite with a simple and rapid method (Fig. 1), and to be used for the removal and photodegradation of the tetracycline antibiotic (TC). Effective parameters on tetracycline removal such as pH, initial TC concentration, and contact time were tested. The experimental results showed that g-C3N4/Go has the excellent performance in photocatalytic degradation of tetracycline, up to 81% after 3 hours at an optimized pH of 4.
