Formation and antibacterial properties of graphitic carbon nitride

Abstract

Graphitic carbon nitride (g-C3N4 ) was synthesized by pyrolysis of thiocarbamide and a subsequent polymerization of its products at 500 °С. After grinding the synthesized material, aqueous suspensions with the concentrations of the particles of 100–300 μg/ml were prepared from it. The antibacterial activity of the material under irradiation with the LED’s visible light for 60–120 min was confirmed for Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa.
