graphitic carbon nitride%europium%photocatalytic%synthesis%doping%rare earths
Europium-doped graphitic carbon nitride was synthesized by an easy method and characterized by X-ray diffraction (XRD), ultraviolet-visible diffuse reflection spectroscopy (UV-Vis DRS), Fourier transform infrared spectroscopy (FTIR), photolu-minescence spectra (PL) and transmission electron microscopy (TEM). The effect of dopant concentration on the rate of photocata-lytic degradation was investigated through degrading methylene blue aqueous solution. The results indicated that the europium-doped samples all possessed increased photocatalytic activity and the optimal europium content was 0.38 wt.%. Moreover, a possible photo-catalytic mechanism for the europium-doped graphitic carbon nitride was proposed.
