Recent advances in hydrothermal synthesis of facet-controlled CeO2-based nanomaterials.

CeO2-based nanomaterials have received tremendous attention due to their variety of applications. This paper is focused on the recent advances in facet-controlled CeO2-based nanomaterials by the hydrothermal method. CeO2-based nanomaterials with controllable size and exposed facets can be prepared by adjusting the reaction parameters. Moreover, doping and loading metals can improve the oxygen storage capacity (OSC) of CeO2 and its catalytic activity. Various research studies on catalytic applications such as CO oxidation, water–gas shift reaction (WGSR), decomposition of hydrocarbons, and photocatalytic reaction have been carried out to exhibit the high potential of facet-controlled CeO2 nanomaterials. This review will provide readers with various ideas for facet-controlled CeO2-based nanomaterials. [ABSTRACT FROM AUTHOR]
