S. Sugunan et A. Paul, Basicity and catalytic activity of ZrO2-Y2O3 mixed oxides in the oxidationof cyclohexanol, REACT KIN C, 65(2), 1998, pp. 343-348
Acidity/basicity of mixed oxides of ZrO2-Y2O3 activated at various temperat
ures were determined by a titration method using Hammett indicators. The ac
tivity of these oxides towards liquid phase oxidation of cyclohexanol are a
lso reported. The activity data parallel the basicity of these oxides.
