Abstract
A series of rare earth oxide mixed manganese nodules (perovskite type mixed oxides) have been prepared by coprecipitation method followed by calcination at 900 degrees C and characterized by different technique s. The effect of rare earth ions on the surface, textural and catalyti c activity for the oxidation of CO, and decomposition of H2O2 have bee n discussed. The activity for CO oxidation followed an order: Pr great er than or equal to La > Nd > Yb > Dy > Tb > Sm > Tm > Gd > Eu > Ce. ( C) 1996 Academic Press, Inc.
