Abstract
Catalysts are typical nanomaterials, perhaps the first nanomaterials in wide applications. Catalysis is a nanoscale phenomenon that has been the subject of research and development for many years, but only recently has it become a nanoscale science of materials and chemistry involving more investigations on the molecular level. Nanomaterial-based catalysts are usually heterogeneous catalysts. The extremely small size of the particles maximizes surface area exposed to the reactant, allowing more reactions to occur. However, thermal stability of these nanomaterials is limited by their critical sizes; the smaller the crystallite size, the lower the thermal stability. In this chapter the characterization of metal oxides such as CeO2, TiO2, and ZnO and some of their applications as catalysts for methane combustion and photocatalysis is described. The effects of mixed oxides, and mixed phases were investigated.
