Abstract

 

Nanoparticles and methods for their preparation are described. Porous CeO2 nanoparticles may be made by contacting Ce(NO3)3 with a base to form a mixture, and converting the mixture into a composition including one or more porous CeO2 nanoparticles. Nanoparticles may be made by contacting Ce(NO3)3 with a base to form a mixture including the nanoparticles. Porous CeO2 nanoparticles may have a high oxygen vacancy concentration, a high specific surface area, a high oxygen storage capacity, and/or a high specific Ce3+ ratio. The porous CeO2 nanoparticles may be used as a co-catalyst in a catalyst system or as a catalyst carrier.
