Synthesis and characterization of graphitic carbon nitride g-C3N4
Abstract
The carbon graphitic nitride was synthesized at different temperature, in the range of 450-650oC. All obtained materials were characterized by diffraction of X-Ray (XRD), Infrared spectrometry (IR), Ultraviolet-Visible diffusive reflectance (UV-DRS). The XRD and IR results showed the formation of g-C3N4 phase only form 500oC to 650oC. At higher temperature calcinations, the g-C3N4 decomposed in gases. The UV-DRS spectra indicated the reduce of band gapenergy, from 2.75 to 2.54 eV, when increasing the temperature calcination. The catalytic test evaluation was carried out by degradation of Methylen blue (MB) and Rhodamin B (RhB).The obtained results showed the best degradation yield of MB on g-C3N4 550 (84.2%) and the one of RhB on g-C3N4 600 (~100%).
