Aminopropyl-functionalized mesoporous silicas as CO2 adsorbents
Open accessAbstract
Abstract A range of mesoporous silica substrates were functionalized with 3-aminopropyltrimethoxysilane to form hybrid products suitable for carbon dioxide adsorption. A ‘cylindrical pore’ model was employed to characterize the extent of surface modification per unit substrate surface area and to permit its comparison on a common basis. The extent of surface functionalisation varied with substrate morphology. Combined DTA/TGA was used to characterise CO2 adsorption. Substantial reversible CO2 adsorption capacities were observed under anhydrous conditions (at 20 °C). In the presence of water, CO2 capacity was enhanced, but the rate of desorption was diminished.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
