The present disclosure relates to a method of making a zeolite. The method includes mixing an aluminum nitrate with an aqueous solution of NaOH to form a first mixture followed by mixing silica gel with the first mixture to form a second mixture. The second mixture is heated with microwave irradiation to form a first sample. The method further includes washing, drying, and ion exchanging the first sample with ammonium nitrate to form a second sample. The method includes calcining the second sample to form the zeolite, wherein the method does not use a seed or a structural directing agent.

A method of fixating COto form a substituted oxazolidinone is described. The method includes mixing a nickel-based metal-organic framework (Ni-MOF) catalyst of formula [Ni(BTC)(HO)]&#xb7;(DMF)(HO), a cocatalyst, an aromatic amine, and at least one epoxide to form a reaction mixture, and further contacting the reaction mixture with a gas stream containing carbon dioxide to react the carbon dioxide in the gas stream with the epoxide and the aromatic amine to form a substituted oxazolidinone mixture. The method further includes adding a polar protic solvent to the substituted oxazolidinone mixture, centrifuging, and filtering to produce a recovered Ni-MOF; and further washing the recovered Ni-MOF with an organochloride solvent and drying for at least 5 hours to produce a recycled Ni-MOF.
