Metal-free hybrid nanocomposites of graphitic carbon nitride and char: Synthesis, characterisation and photocatalysis under visible irradiation
Original language description
The hybrid nanocomposites of graphitic carbon nitride (g-C 3 N 4 ) and char were synthesised from melamine and hydroxyethyl cellulose/glucose to obtain metal -free photocatalysts active under visible irradiation. The nanocomposites were tested for the degradation of phenol and ofloxacin. Methods: The nanocomposites were characterized by elemental and thermal analysis. Their electronic properties were studied by UV - Vis and photoluminescence spectroscopy. Texture and morphology were studied by physisorption of nitrogen, X-ray diffraction, infrared spectroscopy, X-ray photoelectron spectroscopy, and by transmission electron microscopy. The photocatalytic experiments were performed under the LED irradiation of 420 nm. Significant findings: Hydroxyethyl cellulose and glucose formed char which was incorporated in the g-C 3 N 4 structure. The char acted as an electron collector enabling the separation of photoinduced electrons and holes. In this way, the photocatalytic activity of g-C 3 N 4 increased and 96% of ofloxacin was degraded during after 120 min. In addition, in this work the total combustion of graphitic carbon nitride up to 800 o C was investigated for the first time.
