Immobilization of exfoliated g‐c3n4 for photocatalytical removal of organic pollutants from water
Abstract
Graphitic carbon nitride (g‐C3N4) was synthesized from melamine and exfoliated by thermal treatment. Exfoliated g‐C3N4 particles were immobilized by electrophoretic deposition from an ultrasonically treated ethanolic suspension aged up to 12 weeks. During the aging of the suspension, the separation of particles bigger than 10 μm was observed. The separated stable part of the suspension contained particles with a relatively uniform size distribution, enabling the fabrication of g‐C3N4 films that were stable in a stirred aqueous solution. Such stable immobilized particles of exfoliated g‐C3N4 are reported for the first time. The photocatalytic activity of such layers was evaluated using aqueous solutions of Acid Orange 7 (AO7) and 4‐chlorophenol (4‐CP). The photocatalytic decomposition of AO7 was faster in comparison with the decomposition of 4‐CP. Mineralization was observed in the case of AO7, but not in the case of 4‐CP, where the decrease of 4‐CP concentration is due to 4‐CP polymerization and the formation of a dimer, C12H8Cl2O2. This indicates that the use of g‐C3N4 as a photocatalyst for oxidative degradation of organic compounds in water is limited. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.
