Nanocolloquium Series Spring 2021
UNAM Nanocolloquium seminars focuses on advancements in the field of nanoscience and nanotechnology. The seminars presents the most recent developments in these exciting fields.
Date and Time: April 16, 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.
