Ionothermal Synthesis of High Silica Zeolites in Deep Eutectic Solvents (DES)
Phase-pure high silica zeolites have been synthesized using different deep eutectic solvents for the first time. ZSM-5 was made in tetrapropylammonium bromide/pentaerythritol. The reaction is affected by the amounts of seeding, water content, and organic structure-directing agent (SDA). Sodalite …

Theoretical Study of the Electronic Structure and Reactions Involving Oxygen-Bridged Cu-Pairs in Zeolite Catalysts for Lean Nitric Oxide Abatement
… Cu-ion pairs ([CuOxCu]2+) are likely to be highly stable for conditions found in high-silica zeolites. Further, both types are stable over a wide range of Cu separations, and the latter exhibits a rich variety of structural isomers. These results provide insight into the role of Cu pairs in …
