Quantachrome Instruments Advances In The Physical Adsorption Characterization Of Mesoporous Zeolites

We welcome you to attend our webinar on "Advances in the physical adsorption characterization of mesoporous zeolites" presented by Quantachrome's Director of Applied Science, Dr. Matthias Thommes. Comprehensive textural characterization of nanoporous materials has become more important than ever for the optimization of novel systems used in many important existing and potentially new applications. Applications of hierarchical nanoporous materials such as mesoporous zeolites require an in-depth pore structural characterization. Detailed insights about the pore architecture (e.g., pore size , pore size distribution, pore volume, and pore interconnectivity) are particularly important because they control transport phenomena and diffusional rates and govern selectivity in catalyzed reactions. The most popular method to obtain surface area, pore size, pore size distribution and porosity information from powders and porous solids is gas adsorption. Despite the major progress achieved in the field of physical adsorption characterization during the last 20 years, new challenges emerged concerning the surface and textural characterization of nanoporous materials exhibiting complex pore networks as can be found for instance in mesoporous zeolites. In fact , major advances have been made during recent years concerning the development of mesoporous zeolites which exhibit hierarchical pore structure with an appropriate balance of micropores (pore width less than 2 nm), mesopores (2-50 nm) and macropores (greater than 50 nm). The network of interconnected micro and mesopores facilitates efficient transfer of fluids to and from active sites located predominantly within the micropores leading to benefit to benefits in numerous catalytic applications.
