چکیده:

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 .
