Preliminary scope of work in English |
A thorough understanding of the mechanisms at play on the atomic level is indispensable to tailor the mass transport properties of porous materials effectively. Achieving this level of comprehension necessitates a synergistic approach, combining experimental investigation with computational simulations. Numerous studies have highlighted the significant role of flexibility in influencing the adsorption and diffusion processes of molecules closely fitting within microporous structures. Changes in flexibility may be triggered by changes in temperature, pressure, and chemical composition, as well as by the presence of guest molecules (guest-induced flexibility). This work aims for a combined experimental and computational approach to explore the impacts of framework flexibility and internal defects across selected hydrocarbon@zeolite systems. Progress in modeling the mass transport properties of porous materials promises to significantly streamline the screening process, ultimately enhancing capabilities for targeted adsorption and improvements in catalytic performance. |
