Surface acidity/Basicity of mixed oxides of La and Zn activated at three different temperatures were determined. The data have been correlated with the catalytic activity for liquid phase reduction of cyclohexanone in isopropanol.

Abstract:
The surface acidity and basicity of oxides of Sm and Zr
and their mixed oxides have been determined using a set of
Hammett indicators. The data have been correlated with
the catalytic activity of these oxides towards the liquid
phase reduction of cyclo-hexanone in 2-propanol.

Abstract:
Acid/base strength distribution of Y2O3 and its mixed
oxides with alumina catalysts are measured on Hammett
acidity function scale and expressed in terms of H0max
value. Basicity of Y2O3 increases with increase in activation
temperature and for mixed oxides the basicity increases
with increase in concentration of Y2O3, in the catalyst.
