This chapter describes the synthesis of ceria nanoshapes (cubes, rods, and octahedra) and detailed characterization of their structure and exposed surface facets. We show how the surface facets influence catalytic performance for the low-temperature water gas shift reaction. The use of Fourier transform infrared spectroscopy provides insights into the mechanistic steps involved in this industrially important reaction. Ceria is a versatile material used in diverse areas such as medicine, fuel cells, sensors, and water treatment, but the primary focus of this chapter is on heterogeneous catalysis by ceria.
