Abstract

A novel kind of high-capacity, highly selective CO2 adsorbent, which is a CO2 "molecular basket" was recently developed. By loading the sterically branched polymer polyethylenimine (PEI) with numerous CO2-capturing sites such as amino groups, into the large pore volume of MCM-41, its adsorption capacity was significantly increased. Preparation approaches to further improve the CO2 adsorption performance of this molecular basket were reported. The synergetic effect of the MCM-41 on the adsorption of CO2 by the PEI was discussed. A novel CO2 molecular basket based on PEI modified mesoporous molecular sieve of MCM-41 (MCM-41-PEI) was successfully developed. The MCM-41 had a synergetic effect on the adsorption of CO2 by PEI. By loading substances with affinities for different gases to the mesoporous molecular sieve, this concept could be utilized to develop different types of highly selective, high adsorption capacity molecular baskets.
