摘要：

A series of Co-N-C catalysts were prepared by a two-step process including pre-condensation and high-temperature calcination, as well as formamide was used as both nitrogen and carbon sources, and cobalt acetate was employed as the source of cobalt. Then the characterizations of XRD, TEM, N2 adsorption-desorption, and XPS were carried out to investigate the morphology and textural properties of as-prepared Co-N-C catalysts. Moreover, the catalytic activity and reusability of such Co-N-C catalysts were further studied for one-pot synthesis of N-benzyl aniline from nitrobenzene and benzyl alcohol. The results demonstrated that the annealing temperature and nitrogen-doping have remarkable influence on the catalytic activity of Co-N-C catalysts. The Co-N-C/800 catalyst exhibited the best catalytic performance, in which the conversion of nitrobenzene was 99%, and the selectivity of N-benzyl aniline was 99% under 0.6 MPa nitrogen, temperature of 140℃, and reaction time of 12 h. The catalyst was used repeatedly for 5 times, and its activity did not decrease significantly. © 2020, Chemical Industry Press Co., Ltd. All right reserved.
