Adsorption of CO2 on Polyethyleneimine 10k—Mesoporous silica Sorbent: XPS and TGA Studies

A CO2 solid sorbent based on polyethyleneimine 10k (PEI-10k) impregnated into mesoporous silica (MPS) foam was synthesized and utilized to capture CO2 at temperatures ranged from 65 ̊C to 95 ̊C. The calculated nitrogen and carbon contents in the bulk of the PEI-10k/MPS sorbent were similar to the XPS results measured on the surface of the foam, suggesting that the PEI was homogeneously distribute...

Porphyrin based porous organic polymers: novel synthetic strategy and exceptionally high CO2 adsorption capacity.

Iron containing porous organic polymers (Fe-POPs) have been synthesized by a facile one-pot bottom-up approach to porphyrin chemistry by an extended aromatic substitution reaction between pyrrole and aromatic dialdehydes in the presence of small amount of Fe(III). The Fe-POPs possess very high BET surface area, large micropores and showed excellent CO(2) capture (~19 wt%) at 273 K/1 bar.

Promoting Effect of Inorganic Alkali on Carbon Dioxide Adsorption in Amine-Modified MCM-41

Three kinds of inorganic alkali are introduced into tetraethylenepentamine (TEPA)and polyethyleneimine (PEI)-modified MCM-41 as the CO2 adsorbents. FT-IR and TGA are used to characterize the surface groups and the thermal stability of adsorbents. Chemical titration method is used to measure the alkali amounts of adsorbents. Thermo-gravimetric analysis with 10% CO2/90% N2 as the simulated flue g...

A triazine-based covalent organic polymer for efficient CO2 adsorption.

A new triazine functionalized hexagonally ordered covalent organic polymer (TRITER-1) has been synthesized via the Schiff-base condensation reaction between a tailor made triamine 1,3,5-tris-(4-aminophenyl)triazine (TAPT) and terephthaldehyde. This ordered porous polymer showed a high BET surface area (716 m(2) g(-1)) and an excellent CO2 uptake capacity of 58.9 wt% at 273 K under 5 bar pressure.

Polyethyleneimine Incorporated Metal-Organic Frameworks Adsorbent for Highly Selective CO2 Capture

A series of polyethyleneimine (PEI) incorporated MIL-101 adsorbents with different PEI loadings were reported for the first time in the present work. Although the surface area and pore volume of MIL-101 decreased significantly after loading PEI, all the resulting composites exhibited dramatically enhanced CO2 adsorption capacity at low pressures. At 100 wt% PEI loading, the CO2 adsorption capac...
