Abstract

This paper introduces a simple thermal-assisted method to synthesize Vanadium-doped Graphitic carbon nitride (V doped g-C3N4) and the investigation on their structure, physical properties and photocatalytic ability using different techniques. The results of X-ray diffraction patterns (XRD) show the impact of V-doping on the structure of host materials. However, the effect of V-doping on oscillate properties doesn't show strongly through Fourier transform infrared (FTIR) spectra. The results of UV-vis spectroscopy show that the basic absorption edge of material tends to shift towards the long wave length as the concentration of doping increases. Photocatalytic results indicate that V-doping enhances the photocatatytic activity of g-C3N4 significantly. Photocatalytic efficiency increased remarkably in all V-doped samples in which 7mol % V-doped g-C3N4 degraded almost 100% RhB in the solution in 40 minutes of light exposure. This is 6 times stronger than the photocatalytic performance of pure g-C3N4.
