Borane-modified graphene-based materials as CO2 adsorbents

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.
