摘要：

The porosity of gamma-alumina-based materials is an important parameter affecting the extent of fluorination (aerogels > commercial gamma-Al2O3 > xerogels) and, consequently, also the textural, acidic and catalytic properties of the final fluorinated materials. Only the highly fluorinated aluminas having strong Lewis acidic sites catalyse the isomerisation of CHF2CHF2 to CF3CH2F.
