ZnCo-POPs球形材料衍生双金属催化剂协同催化烯烃与空气的环氧化
Synergistic Catalysis Epoxidation of Olefins and Air by Bimetallic Catalysts Derived from ZnCo-POPs Spherical Materials
摘要
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 N,N-dimethyl 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.关键词
