Photocatalytic Degradation of Selected Pharmaceuticals Using g-C3N4 and TiO2 Nanomaterials

Original language description

Exfoliated graphitic carbon nitride (g-C3N4) and two commercially available nanomaterials from titanium dioxide (P25 and CG300) were tested for the photocatalytic degradation of paracetamol, ibuprofen, and diclofenac. Prior to photocatalytic experiments, the nanomaterials were characterized by common methods, such as X-ray diraction, UV-VIS diuse reflectance spectroscopy, Fourier transformed infrared spectroscopy in attenuated total reflection mode, transmission electron microscopy physisorption of nitrogen, and dynamic vapor adsorption of water. The sizes and specific surface area of the TiO2 nanoparticles were 6 nm and 300 m2/g for CG300 and 21 nm and 50 m2g1 for P25. The SSA of g-C3N4 was 140 m2/g. All photocatalytic experiments were performed under UV (368 nm), as well as VIS (446 nm) irradiation. TiO2 P25 was the most active photocatalyst under UV irradiation and g-C3N4 was the most active one under VIS irradiation. Photodegradation yields were evaluated by means of high performance liquid chromatography and reaction intermediates were identified using gas chromatography with mass detection. Paracetamol and ibuprofen were totally removed but the intermediates of diclofenac were observed even after 6 h of irradiation. Some intermediates, such as carbazole-1-acetic acid, 2,6-dichloraniline, and hydroxylated derivates of diclofenac were identified. This study showed that g-C3N4 is a promising photocatalyst for the degradation of pharmaceuticals in an aqueous environment, under visible light.
