The present work is aimed to produce dimethyl carbonate by coupling of CH3OH and CO2 with 2-cyanopyridine over ZnO–CeO2 catalysts prepared by co-precipitation method. These catalysts were characterized by XRD, TEM, UV-Vis DRS, BET surface area, CO2 and NH3-TPD techniques and applied forthe titled reaction. Among the investigated catalysts 10ZnO–90CeO2 catalyst with CeO2 crystallite size 8.0nm exhibited 96% conversion of methanol with 99% selectivity to dimethyl carbonate. The superior catalytic activity is a unified effect of crystalline size of CeO2 and presence of an optimum number of acidic and basic sites. This protocol offers enhanced conversion of methanol with the simultaneous conversion of 2-cyanopyridine into 2-picolinamide by removing water molecules formed in the reaction.
