Synthesis of Stable Tetraethylenepentamine-Functionalized Mesocellular Silica Foams for CO2 Adsorption
Various amounts of tetraethylenepentamine (TEPA) loading on mesocellular silica foams (TEPA-MSF-x) were fabricated via a chemical grafting method in this study. The performance of dry 15% adsorption on the TEPA-MSF-x was tested by a microbalance at 348 K under ambient pressure. Experimentally, ad...
