Methods for preparing molecular sieves using 1,1-diethyl-2,6-dimethylpiperidin-1-ium and molecular sieves prepared therefrom

Abstract

A method for preparing a molecular sieve, wherein the method comprises forming a synthesis gel comprising an aluminum source, a silicon source, an organic structure directing agent, water, an alkali source, and, optionally a seed crystal; and heating the synthesis gel to obtain the molecular sieve; wherein the organic structure directing agent comprises a 1,1-diethyl-2,6-dimethylpiperidin-1-ium cation, and the molecular sieve comprises a framework type that is not AEI. Also disclosed are molecular sieves prepared according to the disclosed methods, selective catalytic reduction catalysts comprising the disclosed molecular sieves, and methods for selective catalytic reduction using the disclosed selective catalytic reduction catalysts.
