Webisotherms is complicated because the typical pore size of M41S materials is only approximately 7]13 molecular diameters of the adsorbate molecule, and assump-tions made in the traditional models such as Brunauer-Emmett-Teller BET 27 .wx and Barrett-Joyner-Halenda BJH 28 become much less realistic. Thus, develop- .wx WebFeb 18, 2024 · Brunner−Emmet−Teller (BET) and Barrett-Joyner-Halenda (BJH) measurements were carried out to examine the internal pore structures of MCM-41 and nitrogen-adsorption-desorption isotherms were plotted using a specific surface meter (JW-BK200C, JWGB Sci. & Tech. Co., Ltd., Beijing, China).
