Fluorinated organo-silica gels doped with tetra-n-propylammonium perruthenate (TPAP) are excellent catalysts for the aerobic oxidative dehydrogenation of alcohols in supercritical CO2 (scCO2). Their activity and stability are subtly dictated by structure, depending on the degree of fluorination and the lenght of the fluoroalkyl chain linked to the silica network. Such dependence reflects the hydrophilic-hydrophobic balance (HHB) of the matrix, as evaluated by diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy.

Abstract

Fluorinated organo-silica gels doped with tetra-n-propylammonium perruthenate (TPAP) are excellent catalysts for the aerobic oxidative dehydrogenation of alcohols in supercritical CO2 (scCO2). Their activity and stability are subtly dictated by structure, depending on the degree of fluorination and the lenght of the fluoroalkyl chain linked to the silica network. Such dependence reflects the hydrophilic-hydrophobic balance (HHB) of the matrix, as evaluated by diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy.
