Structural changes in the methanol-to-olefin (MTO) catalyst SAPO-34 after/during hydrothermal treatment
Characterization of catalytic sites in microporous materials using solid-state NMR. An ex-situ and in-situ high temperature flow study.
Characterization and studies of Si and Brønsted site developments in SAPO-18 and SAPO-34 during and after hydrothermal treatments
In-Situ Atomic Force Microscopy Study of the Dissolution of Nanoporous SAPO-34 and SAPO-18
In-situ atomic force microscopy has been used to investigate the dissolution behavior of industrially relevant silicoaluminophosphate catalysts SAPO-34 and SAPO-18. Spiral growth is prevalent on these materials and it is common for the spirals to be composites of multiple dislocation sources. The sp...

Anatomy of screw dislocations in nanoporous SAPO-18 as revealed by atomic force microscopy
Defects in solids are often the source of functional activity, the trigger for crystal growth and the seat of instability. Screw dislocations are notoriously difficult to study by electron microscopy. Here we decipher the complex anatomy of one such defect in the industrially important nanoporous ca...

Nanoporous Intergrowths: How Crystal Growth Dictates Phase Composition and Hierarchical Structure in the CHA/AEI System
Some of the most important nanoporous materials that are used for industrial applications are formed as intergrowths between structurally related phases. Further, the specific properties and functions are often strongly related to the nature of these intergrowths. By their nature such structures are...
CHA/AEI intergrowth materials as catalysts for the Methanol-to-Olefins process
A series of SAPO-34/SAPO-18 intergrowth materials were prepared with a range of silicon content from 0.5 to 7.0%, where low levels of silicon resulted in SAPO-18 and higher levels resulted in CHA/AEI intergrowths. These materials were tested for their performance in the Methanol-to-Olefins reaction....
