The effect of zeolite type Supports and additives on the catalytic properties of nano Perovskites for CO oxidation

Tow Perovskite type’s powder with different supports and using of different additives were synthesized via wet impregnation method. The aim of this work was the investigation of effect of zeolites as a novel supports. For several Perovskite phases, the temperature between 920 K and 1050 K are suitable to produce nearly pure phase which are easily reducible to nano particles. The prepared samples were characterized by SEM, SPM , XRD and catalytic evaluation for oxidation of CO. zeolite supported samples show better avtivity than alumina supported ones .
