The characterization of support and catalyst were confirmed by the measurements of X-ray, SEM, Raman and BET. High surface area of titanium dioxide incorporated with the solid solutions of Ce0.9Zr0.1O2 has the best activity. Titanium dioxide incorporated with Ce0.9Zr0.1O2 provides a means for oxygen transfer and enhances the reaction activity for the CO conversion in the H2-rich stream. The promotion of CO oxidation becomes weaker as the amount of TiO2 is increased above 20%. A small amount of TiO2 such as 5%CuO/Ce0.9Zr0.1O2-TiO2(10%) can be a good candidate for oxidation (PROX) unit in a polymer electrolyte membrane fuel cell system to remove CO.
