Abstract

A series of materials based on mesocellular siliceous foam (MCF) and SBA-15, but modified with branched and linear polyethyleneimine (PEI) were synthesized and investigated as CO2 adsorbents. PEI modified MCFs, have higher PEI loadings than SBA-15 and, consistent with this exhibit higher CO2 capacities on both a volume % and weight % basis. Performing CO2 adsorption at modestly elevated temperatures is beneficial for achieving good adsorption and desorption rates.
