Ultrasound-assisted co-precipitation synthesis of mesoporous Co304-Ce02 composite oxides for highly selective catalytic oxidation of cyclohexane
文献摘要：
The one-step highly selective oxidation of cyclohexane into cyclohexanone and cyclohexanol as the essential intermediates of nylon-6 and nylon-66 is consi-derably challenging.Therefore,an efficient and low-cost catalyst must be urgently developed to improve the effici-ency of this process.In this study,a Co3O4-CeO2 compo-site oxide catalyst was successfully prepared through ultrasound-assisted co-precipitation.This catalyst exhibited a higher selectivity to KA-oil,which was benefited from the synergistic effects between Co3+/Co2+and Ce4+/Ce3+redox pairs,than bulk CeO2 and/or Co3O4.Under the optimum reaction conditions,89.6％selectivity to KA-oil with a cyclohexane conversion of 5.8％was achieved over Co3O4-CeO2.Its catalytic performance remained uncha-nged after five runs.Using the synergistic effects between the redox pairs of different transition metals,this study provides a feasible strategy to design high-performance catalysts for the selective oxidation of alkanes.
