Abstract 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 (O2) 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, O2 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 O2 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 O2 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.

氧化铈（IV）纳米复合材料：催化性能和工业应用

摘要 这篇综述文章为氧化铈 (CeO2)-金属氧化物纳米复合材料作为催化剂的应用提供了新的见解，该复合材料具有增强的还原性和改善的氧气 (O2) 储存能力，特别是在包括燃烧、氧化、环氧化和氧化还原在内的各种化学反应过程中。 . CeO2-金属氧化物的相互作用在控制催化剂的粒径、O2 可用性和抗焦炭性能方面起着重要作用。强烈的金属氧化物-CeO2 相互作用还有助于生成小而高度分散的颗粒，在催化过程中阻止催化剂颗粒的烧结，从而提高催化剂的 O2 可用性。事实上，CeO2 不仅为多相催化剂提供了活性载体，但也在金属-支撑界面处创建了一个新的活性位点，以通过表面 O2 空位产生更强的纳米粒子键合。因此，这产生了在许多工业应用中具有良好反应速率和催化稳定性的多相催化体系，例如 CO2 加氢、CO 氧化、生物柴油生产、气体还原、光催化和甲烷蒸汽重整。
