The CeO2/CuO catalysts were synthesized by the hydrothermal method. The study shows that the particle-like CeO2 can self-assemble into the rod-like CeO2 during the hydrothermal procedure and the rods of CeO2 become shorter with the decrease of Ce/Cu molar ratio. The highly dispersed CuO is favorable for CO oxidation at lower temperature, and the bulk CuO can help CO oxidation at higher temperature due to the limitation of reduction.

Supported Copper Catalysts

Catalysts based on combinations of copper and cerium oxides are interesting alternatives to noble metal ones for processes involved in the production/purification of hydrogen produced from hydrocarbons or biomass like the water–gas shift or the preferential oxidation of CO reactions.
