Abstract
A series of Ce–Cu nanoparticle oxide catalysts were prepared by a modified reverse microemulsion method using a mixture of cerium and copper nitrate solutions and various precipitating agents ((NH4)2CO3, NaOH or tetrapropylammonium hydroxide). The obtained precursors were transformed into the mono-phase oxide forms by calcination in air atmosphere. The catalytic activity of the CuxCe1−xO2 nanoparticles in the methanol and ethylene incineration depended on both copper loading and size of nanocrystallites. Optimal composition as well as morphology of the active catalytic Ce–Cu oxide systems were proposed.
