ABSTRACT
This work highlights two different
strategies for functionalizing amino groups in MOF-808: directly bind amino acid to
zirconium cluster and polyamine incorporation via nucleophilic substitution. The
synthesized MOF-808-AAs and MOF-808-PAs exhibited remarkable CO2 uptake capacity with amino group. Furthermore, under humidity condition, the CO2 uptake capacity is greatly enhanced by dynamic breakthrough measurements. This
research reveals that amine-functionalized MOF-808 are promising sorbents for
direct air capture of CO2 and propose a new strategy for functionalizing
MOFs with post-modification for other applications.
