Template Design and Economical Strategy for the Synthesis of SSZ‐13 (CHA‐Type) Zeolite as an Excellent Catalyst for the Selective Catalytic Reduction of NOx by Ammonia

SSZ‐13 zeolite, a CHA‐type aluminosilicate, has attracted wide attention recently because of its extraordinary physiochemical properties and excellent potential for applications in catalysis. In this work, SSZ‐13 zeolite was synthesized using choline chloride as a CHA‐topology construction template. This new template has a low cost and is environmentally friendly. Specifically it has the appropriate geometry and functional groups for easy self‐assembly as dual molecules to form the CHA topology, which was verified by self‐prepared organic templates with similar structure and functional groups as well as IR spectroscopy and DFT and potential energy distribution calculations. After ion exchange by Cu cations, the as‐synthesized SSZ‐13 exhibited an outstanding performance for the selective catalytic reduction of NO and showed ≈100 % NO conversions across a wide temperature window of 150–450 °C.
