Under hydrothermal conditions, Fe-SSZ-13 zeolite with CHA structure was synthesized directly using N, N, N-trimethyladamantane ammonium hydroxide (TMAdaOH) as the template. In the synthesis process, iron is added during the preparation of the zeolite gel precursor. After calcination, the obtained zeolite can be used directly as the catalyst without other subsequent treatments such as ion exchange. The species of iron in Fe-SSZ-13 zeolite were studied by XRD, H₂-TPR, UV–Vis, etc. The characterization result proved that the obtained Fe-SSZ-13 zeolite has relatively active iron species, such as the monomer [Fe-(OH)₂]⁺ and the dimer [HO-Fe-O-Fe-OH]²⁺. The Fe-SSZ-13 zeolite was used in the selective catalytic reduction of NO_x with NH₃ (NH₃-SCR) and exhibits good catalytic performance.

在水热条件下，以N，N，N-三甲基金刚烷氢氧化铵（TMAdaOH）为模板直接合成CHA结构的Fe-SSZ-13沸石。在合成过程中，在制备沸石凝胶前体时添加铁。煅烧后，所获得的沸石可以直接用作催化剂，而无需其他后续处理，例如离子交换。通过XRD，H ₂ -TPR，UV-Vis等研究了Fe-SSZ-13沸石中铁的种类。表征结果表明，所得Fe-SSZ-13沸石具有相对较活泼的铁种类，如单体[Fe-（OH）₂ ] ⁺和二聚体[HO-Fe-O-Fe-OH] ²⁺。该Fe-SSZ-13沸石在所述选择性催化还原NO的使用_XNH ₃（NH ₃ -SCR）并具有良好的催化性能。
