Adsorption and Diffusion in Nanoporous Materials
Adsorption and diffusion processes are strongly affected by the pore systems and surface properties of nanoporous materials. Physical adsorption on solids is determined by interaction of molecules in the fluid phase with a given surface. Pore geometries and surface functionalities are factors that can be modified in order to alter diffusive and/or adsorptive properties of a given material. Generation of hierarchical pore systems has been shown to generate catalysts with significantly improved performance as the result of enhanced diffusivity. Investigation of adsorptive and diffusive properties of nanoporous materials allows for a better understanding of the processes involved, which in turn allows design of optimized materials for catalytic and adsorptive applications.
