Front Cover: Modification of Zeolite Morphology via NH4F Etching for Catalytic Bioalcohol Conversion (ChemCatChem 6/2024).

This article, published in ChemCatChem, explores the modification of zeolite morphology through NH4F etching for catalytic bioalcohol conversion. The researchers investigated the effects of fluoride etching on small and medium pore zeolites like FER, MOR, and ZSM-5, finding that it created mesoporosity while retaining structural integrity and acidic properties. However, they also observed adverse effects on large pore zeolites like FAU, leading to the breakdown of the microporous framework. The study highlights the complex relationship between zeolite framework, etching process, and catalytic efficiency. [Extracted from the article]
