Recent progress in ceria-based catalysts for the dry reforming of methane: A review

• Recent developments in the ceria-based catalyst for dry reforming of methane. • Thanks to redox and acid-base properties for excellent carbon resistance and stability. • Surface interaction and surface modification affect reforming and de-coking pathway. • Regeneration of carbon deposits is possible by various gasification treatments. The mitigation of CO 2 and CH 4 emissions is feasible by transforming them into valuable syngas via the dry reforming of methane (DRM). However, the problem of catalyst deactivation has restricted its industrial application. Therefore, the development of catalysts for an effective reforming process has been attracted enormous attention. Ceria has a high potential as it can serve as both catalyst support and metal active site for adsorption and dissociation of CO 2 and CH 4 . Material properties, such as redox and acid/base properties, and oxygen storage capacity, greatly affect catalytic behavior and performance, as well as coke inhibition in the DRM. This review aims to provide an up-to-date summary on the DRM over ceria-based catalysts, including aspects of the catalysts, reaction mechanism, deactivation, and regeneration studies. This review also proposes governing factors and new ways for improving the process, to provide a more rational to designing an ideal ceria-based catalyst for DRM.
