A short review on the promotional effects of ceria-based catalyst for dry reforming methane
Dry reforming of methane (DRM) appears as a promising process for the industrial production of syngas in comparison to other conventional reforming technologies. However, DRM process suffers from catalyst deactivation induced by carbonaceous species which reduces the catalyst lifespan. Currently, ca...

| description | Dry reforming of methane (DRM) appears as a promising process for the industrial production of syngas in comparison to other conventional reforming technologies. However, DRM process suffers from catalyst deactivation induced by carbonaceous species which reduces the catalyst lifespan. Currently, catalytic designs in DRM have trended towards the incorporation rare-earth metals. As such, ceria (Ce) based catalyst has recently attracted research interest for its key feature to mitigate catalyst deactivation owing to its complementary redox and oxygen storage properties for the removal of surface carbon deposit. The present short review summarizes on the recent catalytic performance of Ce-based catalyst and impact of ceria redox on the DRM mechanism. The utilization of oxygen vacancies introduced by the Ce redox support enhances the catalytic activity by providing additional bifunctional sites and intermediate species to facilitate the surface reaction rate. This perspective will elucidate the role of oxygen vacancies in Ce supports and fine tune the catalytic performance of DRM for industrial applications. |
