Abstract
A method can include heating an aqueous reaction mixture comprising a silicon source and a boron source and/or an aluminum source in the presence of a diquaternary structure directing agent to a temperature of at least 75° C. to produce a zeolite. A composition can include a borosilicate zeolite, an aluminosilicate zeolite, or an aluminoborosilicate zeolite having a framework symmetry of C2/m and a unit cell with measurements of a of 3.5 Å to 4.5 Å, b of 20.1 Å to 21.1 Å, c of 15.5 to 16.5 Å, and β of 97° to 98°.
