文摘

A series of CO₂ adsorbents were synthesized by functionalizing SBA-15 via stepwise growth of amine-terminated melamine-based dendrimers. The adsorbents contained very high organic loadings (up to 50.3 wt % ) relative to previous reports. In addition to that, CO₂ adsorption measurements demonstrated that primary amine groups are the only active groups within these dendritic structures for CO₂ adsorption. The CO₂ adsorption capacities of these adsorbents (except for fourth generation dendrimer functionalized SBA-15) are improved relative to the unfunctionalized SBA-15. The exception is associated with the completely filled pores of this adsorbent.
