摘要：Co-g-C3N4catalyst was prepared by a simple calcination method using melamine and Co(NO3)3·6H2O as precursors. X-ray diffraction (XRD), Fourier transform infrared spectra (FT-IR) were used to characterize the prepared samples. The results indicated the Co species are successfully coordinated with g-C3N4. Degradation experiments showed that Rhodamine B can be degraded effectively at a very low cobalt doping concentration (0.2 wt %). The enhanced catalytic activity may result from the synergistic effect of visible light photocatalysis and sulfate radical based Co-g-C3N4/PMS system.
