The preferential oxidation of CO (PROX) is the most suitable method for the purification of gas streams rich in H2. CuO/CeO2 catalysts have been developed and presented as a promising alternative for the preferential oxidation reaction of CO - CO-PROX. The aim this work is to synthesize CuO/CeO2 ceramic catalysts by means of the synthesis Pechini's method, characterization and analysis the structures and evaluation of the performance of these materials used in catalytic reaction of CO-PROX. Two samples ceramic catalysts based on CuO/CeO2 were synthesized, the first containing 0.1 mol of CuO and the second containing 0.5 mol of CuO. According to the results, both synthesized samples were ready to be used in a process of converting CO to CO2. However, the sample containing 0.1 mol of CuO was more active than the catalyst sample containing 0.5 mol of the same active species.
