Theoretical study of the first acid dissociation of H2SO4 at a model aqueous surface
Article Abstract:
The calculated reaction free energies for the first acid dissociation of H2SO4 model aqueous surfaces with varying degrees of solvation is discussed. The results indicate that the acid dissociation can be either thermodynamically favored or disfavored depending on the degree of solvation of the acid and the produced ions as well as on the temperature.

Effect of size and extent of sulfation of bulk and silica-supported ZrO2 on catalytic activity in gas- and liquid-phase reactions
Article Abstract:
The catalytic activity of sulfated zirconia catalysts originates from supported sulfuric acid containing water. A demonstration that sulfated zirconia needs water to display activity in the gas-phase and liquid-phase reaction studied, is presented.
