外文摘要：Glycerol carbonate,an important glycerol value-added product,has been widely used as an active intermediate and inert solvent in the synthesis of cosmetics,detergents,chemical intermediates,poly-mers,and so on.The direct carbonylation from glycerol with CO2 is considered a promising route,but still tough work due to the thermodynamic stability and the kinetic inertness of CO2.In this work,highly-selective direct carbonylation of glycerol and CO2 into glycerol carbonate has been achieved over highly dispersed MglnCe-mixed metal oxides(MglnCe-MMO),which were prepared through the topological transformation derived from the MglnCe-layered double hydroxides(MglnCe-LDHs).By precisely modulating the surface basic-acidic properties and the oxygen vacancies,an efficient carbonylation of glycerol with CO2 has been achieved with a selectivity of up to＞99％to glycerol carbonate.Deep investigation into the synergistic catalysis of base-acid sites and oxygen vacancies has been clarified.
