Surface acidities and catalytic activities of acid ...

Apr 02, 2004· 1. Introduction. Acid-activated clays are efficient and relatively inexpensive solid acid catalysts for liquid phase processes. They possess comparatively strong acid sites (H 0 typically quoted in the range −5.6 to −8.2 ) and their part-amorphous nature provides mesoporosity over a wide range of pore sizes.Despite the discovery of many new inorganic mesoporous molecular sieves on which ...
