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.
