Sulphated zirconia (SZ) was synthesized under different precipitation and ageing conditions. Catalysts were characterized by nitrogen adsorption–desorption, thermal analysis, FTIR and Raman spectroscopy. The catalytic performance of these SZ systems in both gas and liquid-phase reactions has been investigated. The effect of precipitation and ageing conditions has been studied and a correlation with catalytic activity has been tried.

Abstract
Sulphated zirconia (SZ) was synthesized under different precipitation and ageing conditions. Catalysts were characterized by nitrogen adsorption–desorption, thermal analysis, FTIR and Raman spectroscopy. The catalytic performance of these SZ systems in both gas and liquid-phase reactions has been investigated. The effect of precipitation and ageing conditions has been studied and a correlation with catalytic activity has been tried.
