Abstract

Cerium oxide (CeO2) is a material that displays a diverse reactivity related to its rich redox chemistry and cooperative acid/base properties, and is used in a variety of applications, including heterogeneous catalysis. However, there remains a need to evaluate the influence of structure-dependent properties on the catalytic performance to provide information that can guide the designing of more active and selective catalysts. In this chapter, the size and crystal plane-dependent properties of CeO2 films and particles are reviewed. Then, the use of shape-controlled CeO2 nanoparticles in various catalytic reactions are discussed and evaluated in view of their shape-dependent properties. The impact of these structure-function relationships on the design of advanced cerium oxide catalystsis discussed, including the potential of shape-controlled CeO2 particles to act as highly tunable supports for catalytic reactions.
