Abstract
A method of carbon dioxide fixation includes contacting a covalent organic framework material with a co-catalyst and an epoxide in the presence of carbon dioxide to form a cyclic carbonate. The covalent organic framework material includes reacted units of a 2,4,6-trimethyl-1,3,5-triazine, reacted units of a 4,4′-biphenyldicarbaldehyde, and palladium nanoparticles. The reacted units of the 2,4,6-trimethyl-1,3,5-triazine and the reacted units of the 4,4′-biphenyldicarbaldehyde form a COF-701, where the palladium nanoparticles are on an outer surface of the COF-701. The co-catalyst is n-tetrabutylammonium bromide.
