Constructing Efficient CuO-Based CO Oxidation Catalysts with Large Specific Surface Area Mesoporous CeO₂ Nanosphere Support.

ABSTRACT: CeO₂ is an outstanding support commonly used for the CuO-based CO oxidation catalysts due to its excellent redox property and oxygen storage-release property. However, the inherently small specific surface area of CeO₂ support restricts the further enhancement of its catalytic performance. In this work, the novel mesoporous CeO₂ nanosphere with a large specific surface area (~190.4 m²/g) was facilely synthesized by the improved hydrothermal method. The large specific surface area of mesoporous CeO₂ nanosphere could be successfully maintained even at high temperatures up to 500 °C, exhibiting excellent thermal stability. Then, a series of CuO-based CO oxidation catalysts were prepared with the mesoporous CeO₂ nanosphere as th
