Abstract
Graphitic carbon nitride (g-C3N4) was synthesized by facile pyrolysis method. XRD pattern confirmed the single phase and hexagonal crystal structure of g-C3N4. FE-SEM studies confirmed the formation of flaky and sheet-like morphology. This hexagonal structured g-C3N4 has good wettability property due to the presence of lone pair of electron in the nitrogen atom. Consequently, the g-C3N4 nanostructure can provide more number of active sites for catalytic reactions. Therefore, the g-C3N4 nanosheets were implied as visible light active photocatalyst for the degradation of organic dye pollutants. From the results, it is evident that g-C3N4 exhibits superior photocatalytic activity towards crystal violet, acridine orange and rhodamine B. Hence, it is proposed that g-C3N4 can be an active photocatalyst towards diverse group of organic dyes.
