摘要：
A simplemethod to prepare highly active RhOx/ceria catalystswith RhOx sub-nanoparticles (diameterb1 nm)is reported, which consist of flash calcination of the ceria-impregnated rhodium oxide precursor. The catalytic performance for CO oxidation is significantly improved with regard to similar conventionally-prepared catalysts due to the formation of more highly active catalytic sites at the oxides interface. © 2012 Elsevier B.V.
