A green route for synthesizing pure silica zeolites with six-membered rings

Green routes for synthesizing pure silica zeolites are attractive but still challenging. Herein, we for the first time report a green route for synthesizing pure silica zeolites with six-membered rings (6MRs) by a combined strategy of ethanol filling and zeolite seeding. As a result, pure silica zeolites with 6MRs, such as SOD, MTN, and NON, could be successfully synthesized.
