Abstract: Examples described herein provide a method of making a nano-sized zeolite. The method comprises dissolving an aluminum source in a first portion of an aqueous solution of a templating agent to form a first mixture. The first mixture is added to a slurry of a silica source in a second portion of the aqueous solution of a templating agent to form an aluminosilicate fluid gel. The aluminosilicate fluid gel is stirred to allow reaction. The aluminosilicate fluid gel is dried to form a dry gel and the dry gel is hydrothermal treated in a hydrothermal treatment holder to form a solid product. The solid product is washed, dried, and calcined.
