| Summary: | Selective catalytic reduction of nitrogen oxides with NH<sub>3</sub> (NH<sub>3</sub>-SCR) is still the most commonly used control technology for nitrogen oxides emission. Specifically, the application of rare earth materials has become more and more extensive. CeO<sub>2</sub> was widely developed in NH<sub>3</sub>-SCR reaction due to its good redox performance, proper surface acidity and abundant resource reserves. Therefore, a large number of papers in the literature have described the research of cerium-based catalysts. This review critically summarized the development of the different components of cerium-based catalysts, and characterized the preparation methods, the catalytic performance and reaction mechanisms of the cerium-based catalysts for NH<sub>3</sub>-SCR. The purpose of this review is to highlight: (1) the modification effect of the various metal elements for cerium-based catalysts; (2) various synthesis methods of the cerium-based catalysts; and (3) the physicochemical properties of the various catalysts and clarify their relations to catalytic performances, particularly in the presence of SO<sub>2</sub> and H<sub>2</sub>O. Finally, we hope that this work can give timely technical guidance and valuable insights for the applications of NH<sub>3</sub>-SCR in the field of NO<sub>x</sub> control.
