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:
An investigation on the physical and chemical characterisation of rare earth oxide
supported vanadia is attempted in the present study. La2O3, Sm2O3 and DY2O3 serve the
purpose of supports. Supported catalysts were prepared and characterised using various
physico chemical techniques. A detailed investigation of acid base properties is also
carried out. The nature of interaction of vanadia with lanthanide oxide is discussed and
the effect of vanadia loading on the activity of the systems towards reactions of industrial
importance is explored.
