Zeolitic and zeotype mateials having the chabazite framework have received much interest for MTO and NOx abatement. We developed synthesis methods using a series of designed organic templates. These templates are effective for F-free synthesis of low-Si SAPO-CHA, including AlPO4-CHA, and chabazite (aluminosilicate) having a wide range of Si/Al ratios.
