Preferential oxidation of CO in H2 over CuO-CeO2 catalysts
Catalysis Today 93-95(2004)241-246,-0001,():
a material calcined at 650℃, ∼5 at.% Cu content is sufficient for maximum activity. Cu-O-Ce phases, comprising copper oxide clusters strongly associated with ceria, are proposed as the active sites for the reaction. No inhibition by CO2is observed at temperatures above 140℃, but the combined effect of H2O and CO2 is stronger, requiring operation at 165℃ for 99% CO conversion and 65% selectivity.
