Several techniques can be employed to measure and evaluate reactant accessibility:
BET Surface Area Analysis: This technique measures the surface area of a catalyst, providing insights into its potential accessibility. Pore Size Distribution: Measuring the distribution of pore sizes helps in understanding how easily reactants can navigate through the catalyst structure. Diffusion Studies: Techniques such as pulsed-field gradient NMR can be used to study the diffusion of molecules within the catalyst pores. Spectroscopic Techniques: Infrared (IR) and Raman spectroscopy can provide information on how reactants interact with the catalyst surface.
