Investigation of photocatalytic performances of graphitic carbon nitride on the alumina support
Textile industries significantly contribute to the generation of wastewater containing various raw materials such as cotton, synthetic fibres, and dyes. Textile dyes are harmful to the environment and human health. Therefore, dye-containing wastewater should be treated to preserve the environment, human health, and natural water resources. Nowadays, conventional wastewater treatment methods can be used in the textile industry. However, those methods have some drawbacks like high cost as well as toxic by- products. Therefore, advanced oxidation processes, like heterogeneous photocatalytic degradation can be used as a more appropriate method for dye removal from wastewater. The present research is focused on the graphitic carbon nitride as a photocatalyst immobilised on the surface of the alumina ceramic ring for photocatalytic degradation of methylene blue (MB) from an aqueous medium under different radiation sources. A metal- free graphitic carbon nitride was prepared through a simple thermal method using urea as a precursor. Deposition of prepared photocatalysts was performed by dip-coating method. The photocatalyst was characterized by XRD, FTIR, and SEM. The photocatalytic activity under ultraviolet (UV-A), visible (warm light), and simulated solar irradiation was examined. The photocatalytic degradation of MB from an aqueous medium was found to increase with increasing irradiation time for all irradiation sources. Furthermore, the radiation source wavelength spectrum plays a significant role in the photocatalytic degradation rate of MB. The immobilised graphitic carbon nitride on alumina ceramic can be convenient for environmental applications, due to easy separation and reusability with high- efficiency removal of MB dye from an aqueous medium.
