摘要：
Selective catalytic reduction (SCR) has been widely used to remove NOx from automobile exhaust and industrial production. Fe-based catalysts with low cost, high activity, and excellent SCR performance have become an active research topic in recent years. The latest research progress of NOx removal by the NH3-SCR method using Fe-based catalysts is summarized. The effects of synergistic interaction between Fe and other elements are analyzed in terms of the redox performance, surface acidity, and catalytic activity of catalysts. In addition, the effects of catalyst morphology and structure on SCR performance are analyzed. Finally, according to the research results of Fe-based catalysts in the laboratory, some practical application problems are considered.
