Síntese de catalisadores nanométricos pelo método Pechini para reação preferencial de CO (PROX).

Abstract

This work had the objective to develop catalytic support of the type Ce1-xCuxO2 to be applied in the preferential reaction oxidation of CO (PROX). The structural analysis showed the presence segregated phases of the majority phase (CeO2). The value of amount the dope element (Cu) did not influence on aspects morphologic of catalytics supports obtained. The textural analysis revealed that the catalytics supports developed presents mesoporous nature structure.
