Abstract
A method of fixating carbon dioxide (CO2) to a substituted oxazolidinone. The method includes mixing a metal-organic framework (MOF), a co-catalyst, at least one para-substituted aromatic amine, and at least one epoxide to form a mixture. The method further includes contacting the mixture with a gas stream containing CO2 to react the CO2 in the gas stream with the epoxide and para-substituted aromatic amine to form a substituted oxazolidinone mixture. The MOF is a UiO-66-X MOF, where X is of formula (I) wherein at least one of R1 to R4 is an allyloxy group, and R1 to R4 are independently an allyloxy group or a hydrogen.
