Abstract
The present disclosure relates to a method of making a zeolite. The method includes mixing an aluminum nitrate with an aqueous solution of NaOH to form a first mixture followed by mixing silica gel with the first mixture to form a second mixture. The second mixture is heated with microwave irradiation to form a first sample. The method further includes washing, drying, and ion exchanging the first sample with ammonium nitrate to form a second sample. The method includes calcining the second sample to form the zeolite, wherein the method does not use a seed or a structural directing agent.
