TiO2-TON zeolite synthesis using an ionic liquid as a structure-directing agent

The 1-butyl-3-methylimidazolium chloride ionic liquid was employed as a structure-directing agent for the preparation of TiO2-TON zeolites under different crystallization conditions. By varying the crystallization parameters (i.e., time, structure-directing agent, and TiO2 content), the ionic liquid...
