Abstract:

As a new type of porous material, porous organic polymers(POPs) is widely used in heterogeneous catalysis because of its unique advantages. In this paper, a series of ZnCo-POPs bimetallic catalytic materials with different compositions were prepared by impregnation method and characterized by means of X-ray diffraction (XRD), field emission scanning electron microscope(FESEM), X-ray photoelectron spectroscopy(XPS), specific surface area and pore size analysis(BET). The Zn0.3Co0.6-POP-250-2 catalyst prepared by impregnation method showed the best catalytic activity. When NNdimethyl formamide(DMF) was used as the reaction solvent and the reaction temperature was 90 ℃ for 5 h, 94.3% α-pinene conversion and 95.2% epoxide selectivity were obtained, and the catalytic activity of the catalyst did not decrease obviously after being recycled for 5 times, which indicated that Zn0.3Co0.6-POP-250-2 catalyst has excellent catalytic performance and good stability.
