The authors studied the CO2 adsorption performances of borane modified graphene-based
materials (B-rG-O). B-rG-O powder was fabricated by reacting graphene oxide with a borane–
THF adduct and showed good CO2 adsorption capacity (1.82 mmol/g at 1 atm) and
recyclability as determined using a CO2 isotherm and breakthrough experiments respectively.
The roles of boron moieties for CO2 adsorption were studied using theoretical calculation
and spectroscopic experiments.
