An Effect of Crucible Volume on the Microstructure and Photocatalytic Activity of the Prepared g-C₃N₄

In this present study, graphitic carbon nitride (g-C₃N₄) was prepared via a thermal condensation of thiourea and characterized by several techniques, which confirmed that the morphology, absorption spectra and recombination of electron–hole pairs for the generated g-C₃N₄ particles were greatly influenced by the volume of alumina crucible. The prepared g-C₃N₄ particles were used as potential photocatalyst for the photocatalytic degradation of nitric oxide (NO). Interestingly, it was observed that the photocatalytic performance of the synthesized g-C₃N₄, prepared under different alumina crucible volume, were different. The detailed photocatalytic investigations revealed that the photocatalytic performance of g-C₃N₄ prepared using 50 mL crucible exhibited the highest removal efficiency of NO. The detailed experiments indicated that the crucible volume had an important impact on the synthesis and photocatalytic properties of prepared g-C₃N₄ materials.
