Characterization of mesoporous materials today is routinely performed recording the adsorption isotherm of nitro gen at 77 K. The pore size distribution (PSD) can subsequently be determined using either thermodynamics or statisticalmechanics based approaches. While nitrogen has evolved as the reference adsorptive, other gases are often used to extractmore information from the isotherm. This contribution is focused on the calculation of a PSD from the water vapor isotherm.
It is demonstrated that water adsorption provides accurate results comparable to the standard nitrogen adsorption.
