| 中文摘要 | Well-dispersed carbon-supported MgO catalysts were prepared using a kind of porous carbon (NC-2) as support and magnesium nitrate solution as MgO precursor by a simple wet impregnation technique. Various characterization techniques, including XRD, N2 sorption, DRIFT. XPS and TPD, were carried out to investigate their physical-chemical properties, the states of MgO species and the interaction between MgO and NC-2 materials. The catalytic properties of MgO/NC-2 catalysts were investigated in the liquid-phase transesterification of dimethyl carbonate (DMC) with diethyl carbonate (DEC). Compared with other kinds of carbon-supported MgO catalysts, MgO/NC-2 shows remarkably higher activity for the formation of ethyl methyl carbonate (EMC). Moreover, the NC-2 supported catalyst possesses very high stability against leaching of active species under test reaction conditions, indicating the truly heterogeneous nature of this catalyst. The presence of relatively rich oxygen-containing surface groups on the NC-2 carbon support should be in favor of the high dispersion of MgO particles, thus being beneficial to the fabrication of active and stable heterogeneous catalysts for the transesterificaiton reaction.
