True Microporosity and Surface Area of Mesoporous SBA-15 Silicas as a Function of Synthesis Temperature
Abstract
A model based on hexagonal mesopores connected by micropores allows evaluation of the porosity of SBA-15 silicas and elucidation of the literature problems on the subject. The presence of micropores in the walls between the mesopores renders unreliable the surface area determination by the Brunauer−Emmett−Teller equation and the microporosity assessment by the t -plot method. A geometrical model allows calculation of the true surface area, as well as the real mesoporous and microporous pore volumes, the wall thickness and the wall density from the total pore volume, the pressure of pore-filling, and the cell parameter. The increase of synthesis temperature leads to a continuous increase of mesopore size and a continuous decrease of microporous volume until the disappearance of micropores for materials synthesized at nearly 130 °C. The results are discussed on the basis of the collective properties of nonionic surfactants.

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.
