Tuning the Polarity of Porous Materials to Impact Adsorption, Diffusion, and Catalysis
Ordered mesoporous (organo)silicas provide a highly tunable platform to modulate the hydrophobicity of their surfaces, through thermal control of surface hydroxyl density as well as the incorporation of organic framework linkers.

Nanoscale hydrophobicity influences the structure and mobility of pore-confined water and the adsorption of solutes, with profound consequences for catalytic reactions. This lecture will describe the evaluation of relative hydrophobicity for internal pore surfaces, the consequences for solvent/solute partitioning, and in situ evaluation of the impact on hydrogenation kinetics.
