Standard Nitrogen Adsorption Data for Characterization of Nanoporous Silicas
Abstract
The nitrogen adsorption isotherm measured at 77 K in the relative pressure range from about 5 × 10 - 7 to 0.988 for a macroporous silica is reported in a tabular form. The isotherm data are in good agreement in the high-pressure range with the reference data published by Gregg and Sing and by Kiselev and Aristov and provide an extension of the latter data to the low-pressure region, for which a reliable reference isotherm was not availalable in the literature. Application of the currently reported reference adsorption isotherm is discussed. The data can be used in comparative analysis (α s -plot or t -plot) to evaluate the external surface area, micropore volume, primary mesopore volume, and total surface area as well as to analyze surface properties of silica-based materials. The adsorption isotherm can also be applied as a statistical film thickness curve in the calculation of the mesopore size distribution.

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.
