Front Cover: Synthesis-Structure-Catalysis Relations in CHA Zeolites Applied for Selective Catalytic Reduction of NOx with Ammonia (ChemCatChem 16/2024)

Abstract

The Front Cover represents the three formation routes of zeolite from different starting materials. Zeolites are crucial industrial catalysts, whereas their crystallization mechanism is still unclear, limiting their rational functional design. Nao Tsunoji and co-workers present the synthesis–structure–catalysis relation of CHA zeolite to get fundamental knowledge for intentionally controlling the function of zeolites. Different starting materials provide three different formation pathways to form CHA zeolites with different properties in the presence of tetraethylammonium hydroxide as an inexpensive organic structure directing agent. The knowledge related to origin of the catalytic durability was obtained based on their structural character, crystallization mechanism, and exhaust gas purification ability. More information can be found in the Research Article by Nao Tsunoji and co-workers (DOI: 10.1002/cctc.202400459).
