Elemental Analysis. The C, H and N content of SBA-15 impregnated with MEA, DEA, DETA, TEPA and PEI were determined by a EURO EA elemental analyzer. Approximately 2 mg of each sample were weight in a tin beaker for each sample. The samples are burned at 1000 °C in a stream of He. After the reduction of NO x compounds the gas stream was separated with a GC column. The products (CO 2, NO 2 , H 2 O) were analyzed with a thermal conductivity detector.Synthesis of SBA-15. 6 g of hydrochloric acid (Sigma Aldrich, 37 wt.%) were added to 188.5 g of DI water and 10.25 g of the surfactant P123 (BASF, M w of 5750 ) under rigid stirring. The solution was stirred for 1 day at 35 °C until a homogenous phase was obtained. Tetraethylorthosilicate (TEOS, Sigma Aldrich, purity ≥ 99 %) was added to the solution and the mixture was kept stirring at 35 °C for additional 24 h. The polymerized solution was aged in autoclaves at 80 °C for 24 h. The solution was filtered with deionized (DI) water for 3 times and the precipitate was dried at 60 °C for 5 h prior to calcination in synthetic air (8 h at 600 °C, heating rate: 2.5 °C/min, total flow rate: 100 ml•min -1 ).

Improvement of the catalytic performance of Ru/C catalysts by selecting acetone as a solvent during the catalyst preparation.

Mesoscopic sorbents are synthesized with various solvents for CO2 capture at elevated pressure and modified with Zr4+ cations to increase the uptake performance.
