This review article provides a new insight on the application of cerium oxide (CeO2)-metal oxide nanocomposites as catalyst with enhanced reducibility and improved oxygen (O-2) storage capacity, especially in the varying chemical reaction processes including combustion, oxidation, epoxidation and redox. The CeO2-metal oxide interaction plays an important role in controlling particle size, O-2 availability and coke resistance properties of the catalyst. Strong metal oxide-CeO2 interaction also assists in generating small and highly dispersed particles, resists sintering of catalyst particles during the catalysis process, and consequently improves the O-2 availability of the catalyst. Indeed, CeO2 not only provides an active support to heterogeneous catalyst, but also creates a new active site at the metal-support interface to produce stronger nanoparticle bonding through the surface O-2 vacancy. This consequently produces a heterogeneous catalytic system with promising reaction rate and catalytic stability in many industrial applications such as CO2 hydrogenation, CO oxidation, biodiesel production, gas reduction, photocatalytic and methane steam reforming.
