Abstract
Graphite phase carbon nitride (g-C3N4) as a novel semiconductor photocatalysts attracted widespread attention in recent years. In this paper, the lamellar g-C3N4 nano-materials prepared from solid urea was used as a photocatalyst to degrade the simulated dye wastewater under visible light irradation. In addition, the photocatalytic degradation performances of g-C3N4 material prepared from conventional and mechanical-conventional methods for degrading organic dye solutions were compared and discussed in detail. The Rhodamine B(RhB), Methylene Blue(MB)and Methyl Orange(MO)water solutions were chosen as simulated dye wastewater. The results showed that these two kinds of C3N4 photocatalyst both has a high decoloration efficiency for these three dyes using visible light. Compared with that from conventional method, the g-C3N4 from mechanical-conventional method has a higher photocatalytic performance, which offered a new process for preparing graphite phase carbon nitride. The molecule structure of dye has an effect on the visible-light decoloration efficiency of g-C3N4. Also, the absorption capability of dye molecules on catalyst gave an important role during this visible-light irradation process.
