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, polymers, 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 MgInCe-mixed metal oxides (MgInCe-MMO), which were prepared through the topological transformation derived from the MgInCe-layered double hydroxides (MgInCe-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.
