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 adsorption of electron acceptors, viz.,7,7,8,8-tetracyanoquinodimethane(TCNQ), 2,3,5,6-tetrachloro-p-
benzoquinone (chloranil) and p-dinitrobenzene
(PDNB) on the surface of three rare earth oxides Y2O3,
Nd203 and Pr6O11 has been studied in acetonitrile and
dioxan. From the radical concentration on the surface
determined using ESR spectral data, the electron donor
strength of the rare earth oxides are reported.
