摘要：A series of ZIF-67/C composite materials were prepared by Co(NO3)(2)center dot 6H(2)O, activated carbon and 2-methylimidazole by stirring at normal temperature. After calcining at 500 degrees C, Co3O4/C products were obtained. Then, the precursor ZIF-67/C and Co3O4/C product were characterized and analyzed by Fourier transform infrared spectrum (FT-IR), UV-visible absorption spectra, powder X-ray diffraction (PXRD), and field emission scanning electron microscope (FE-SEM). In addition, the photocatalytic activity and stability of catalysts were evaluated by decolorization of methylene blue under visible-light and UV light. The experimental results show that Co3O4/C-3 exhibits the best photocatalytic activity for dye degradation. (C) 2019 Elsevier Ltd. All rights reserved.
