Abstract
Considering the characterization of the pore size distribution, for mesoporous and microporous materials, the recommendation of IUPAC is the deconvolution of the integral adsorption equation, using a kernel calculated with the Non-Local Density Function Theory (NLDFT). However, we observed in the literature a lack of systematic studies about the impacts that experimental uncertainty has on the determination of the pore size distribution (PSD). Thus, in this paper, we study the influence of errors related to experimental gaseous adsorption data on the solid characterization, showing the importance of the statistical analysis on the PSD of two idealized materials. The result suggests that this methodology has a strong dependence on the experimental uncertainty of the data used, i.e. the fit of adsorption isotherm is not a self-sufficient hypothesis to reconstruct the pore size distribution.
