采用浸渍法制备了载钴介孔石墨相氮化碳(Co3 O4/mpg-C3 N4)催化剂,并对其进行 X 射线衍射(XRD),红外光谱(FT-IR),N2吸附脱附,紫外漫反射光谱(UV-vis DRS)和光生电流的表征。结果显示, Co3 O4的引入提高了 mpg-C3 N4的光吸收性能,利于其表面光生电子和空穴的分离。将制得的 Co3 O4/mpg-C3 N4用于可见光催化降解水中的亚甲基蓝(MB),其催化效率远高于 mpg-C3 N4,且最佳的钴负载量为3％。

Cobalt modified mesoporous graphitic carbon nitride (Co3 O4/mpg-C3 N4 )was synthesized via a facile impregnation method.The as-synthesized catalyst was characterized by X-ray diffraction (XRD),Fourier trans-form infrared spectroscopy (FTIR),N2 adsorption-desorption analysis,UV-vis absorption spectra (UV-vis DRS)and Photocurrent transient measurement,respectively.It indicated that the addition of Co3 O4 could im-prove the light-absorbing ability of mpg-C3 N4 and enhance the separation efficiency of electron and hole on the catalyst surface.The Co3 O4/mpg-C3 N4 photocatalyst showed prominently enhanced photocatalytic activity for the degradation of methylene blue (MB)under visible-light irradiation than that of mpg-C3 N4 and an optimum content of cobalt doping in the mpg-C3 N4 was 3%.
