Abstract: We have generated molecular models for adsorption in porous glasses that reproduce the complex structures of these materials, using simulations that mimic the quench processes by which Vycor and Controlled Pore Glasses are produced. We have simulated the adsorption and desorption isotherms for two of these model materials. In this work we compare pore size distributions calculated with the Barrett-Joyner-Halenda (BJH) method of isotherm analysis with geometrically-defined pore size distributions.
