  • Catalysts for the transformation of carbon dioxide and glycerol to formic acid and lactic acid and methods of making the same
    Patent number: 12194448
    Abstract: Catalysts and methods for transformation of glycerol and a carbon feedstock, such as CO2, a carbonate salt or a bicarbonate salt, are described herein. Homogeneous catalysts include compounds of formula M[NHC-R-linker]aLbXc, where M is a transition metal, NHC is an N-heterocyclic carbene ligand, R is an alkyl or aryl group, linker is a polar group, L is a neutral ligand, X is an anionic ligand, a ranges from 1-3, b ranges from 0-3, and c ranges from 0-3. Heterogeneous catalysts include a solid support with a catalytically active compound immobilized on the solid support, where the catalytically active compound has the formula M[NHC-R-linker]aLbXc where M is a transition metal, NHC is an N-heterocyclic carbene ligand, R is an alkyl or aryl group; linker is a polar group, L is a neutral ligand, X is an anionic ligand, a ranges from 1-3, b ranges from 0-3, and c ranges from 0-3.
