Synthesis of mesoporous silica gels and determination of their specific surface
Abstract
For the first time, a method has been developed and calculations have been performed for the mesopore surface of solids containing various volumes of micropores, along with mesopores. It has been shown that the method proposed for determination of mesopores' surface is reliable enough. It has been established that formal application of BET method for specific surface determination of this type of adsorbents is not possible. For surface determination of homogeneous mesoporous adsorbents, a simple and practical method has been proposed excluding several procedures connected with the number of molecules adsorbed and the volume of their adsorption site.
