Mechanistic Study of Zeolite Crystallization Published in Nat. Commun.

In this manuscript we use scanning probe microscopy to monitor zeolite LTA crystallization in situ with a spatiotemporal resolution that captures dynamic processes in real time. We report a distinctive pathway involving the formation of gel-like islands from supersaturated solutions comprised of (alumino)silicate molecules. Three-dimensional assembly and evolution of these islands constitutes a unique mode of growth that differs from classical theories. Time-resolved imaging also reveals that growth can occur by (nearly) oriented attachment. At later stages of crystallization, a progressive transition to lower supersaturation shifts growth to a layered mechanism involving two-dimensional nucleation and spreading of layers.

2018 Norman Hackerman Award


Jeff received the 2018 Norman Hackerman Award in Chemical Research from the Welch Foundation. The description for the award is the following along with pictures form the award ceremony that was held at the University of Houston Hilton Hotel:


“Dr. Rimer’s lab has made two significant materials science research discoveries in the past decade. The discovery of a molecule that inhibits calcium oxalate crystallization, the principal component of kidney stones, may lead to a promising therapeutic that has the potential to replace drugs currently used to treat this widespread disease. The second notable discovery is inspiring new methods to optimize the synthesis of zeolites, which are important as catalysts in petrochemical industries.”

Artwork selected for cover of Nature Materials


Our article was featured on the cover of the October 2020 issue of Nature Materials. This work was a collaborative effort between University of Houston (Rimer, Palmer), Stockholm University (Zou), University of Minnesota (Dauenhauer), Utrecht University (Weckhuysen), and Johns Hopkins University (Tsapatsis). This work was part of a Focus Issue on Zeolite Catalysis.

About the Cover: Nanosized zeolites enable better catalytic performance; however, their synthesis is non-trivial. Here, a simple treatment is presented that enables the growth of nanosized fins on zeolites that act as pseudo-nanoparticles, reducing deactivation rates for methanol-to-hydrocarbon catalysts.
