Replay de Svetlana Mintova au colloque de l’UNAM – 16 avril 2021

Nanocolloquium Series Spring 2021

Les séminaires UNAM  se concentrent sur les avancées dans le domaine des nanosciences et des nanotechnologies. Les séminaires présentent les développements les plus récents dans ces domaines passionnants.
Date et heure : 16 avril 2021 – 16:00 via Zoom

Subject: Advancements in nanosized zeolites This presentation will review the progress made in the field of nanosized zeolites including the synthesis, advanced characterizations and related applications. A great effort has been dedicated in recent years to improving the fundamental understanding of zeolite synthesis process, with the overall aim of increasing control over the zeolite properties and structure. The latest studies on zeolite crystallization in colloidal (clear) suspensions prepared by addition of organic or inorganic structural directing agents in comparison to traditional gel synthesis will be revealed. Further understanding on the imperative dependence of zeolite crystallization kinetics’ on the nature and mode of mixing of the initial reactants, leading to the formation of amorphous particles, intermediates, and final crystalline zeolites will be discussed. The first one-pot synthesis of point defect-free nanosized MFI-type zeolite by introducing atomically dispersed metals, as a defect-preventing elements will be presented. The incorporation of metals (Mo, W) in nanosized MFI crystals also modifies other important properties such as (i) structural features, (ii) hydrophobicity (absence of silanols), and (iii) Lewis acidity. Finally examples on the advanced applications of nanosized zeolites in the design of optical devices and medical uses will be given.Prof. Dr. Svetlana Mintova – CNRS, ENSICAEN, Normandy University
