Predicting crystal growth via a unified kinetic three-dimensional partition model
A general simulation approach that can replicate, and in theory predict, the growth of a wide range of crystal types, including porous, molecular and ionic crystals, is demonstrated....
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
Structural changes in SAPO-34 due to hydrothermal treatment. A NMR, XRD, and DRIFTS study
When SAPO-34 is used as an industrial MTO catalyst, structural transformations leading to permanent deactivation are inevitable. The performance loss is linked principally to a redistribution of Si in the material, leading to the formation of Si-islands/aggregates with a concomitant loss of Brønsted...
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...
