High-throughput synthesis and catalytic properties of a molecular sieve with 18- and 10-member rings
Article Abstract:
The structure and catalytic activity of the silicogermanate zeolite ITQ-33 is reported and this material displays straight large pore channels with circular openings of 18-rings along the c axis interconnected by a bidirectional system of 10-ring channels, yielding a structure with large micropore volume. The conditions for synthesis are easily accessible, but are not typical, and are identified using high-throughput techniques.

Supramolecular self-assembled molecules as organic directing agent for synthesis of zeolites
Article Abstract:
The synthesis of zeolite A structures exhibiting high Si/Al ratios up to infinity (pure silica) is described. These materials named ITQ-29, were synthesized using a supramolecular organic structure-directing agent (OSDA) obtained by the self-assembly, through pi-pi type interactions, of two identical organic cationic moieties.

Ship reverses out of bottle
Article Abstract:
A technique for recovering and recycling the organic structure-directing agents (SDAs) that control pore formation in zeolite synthesis is explained. Such improved zeolites with better pore topologies and synthetic techniques will reduce cost of industrial application of zeolites.
