Synthesis and photocatalytic performance of europium-doped graphitic carbon nitride

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 microsc...

More Information
Summary: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.
