Pure-phase ferrierite (FER) zeolite has been synthesized in the presence of small amounts of nonionic surfactants, Tween 20 and Tween 80. The input SiO 2 /Al 2 O 3 molar ratio has been varied over a range of 25 to 150. The results confirm that a small amount of pyrrolidine acts as a template and is
