Dehydra-Decyclization of Tetrahydrofuran for Butadiene Across the Spectrum of Solid Acidity Open
Catalytic C-O bond cleavage and dehydration of tetrahydrofuran was evaluated for a set of progressively stronger solid acid catalysts. Strong acids, namely tungsten-based heteropoly acids, exhibited higher activity and selectivity towards …

The Dynamic Catalytic Activity of Phosphorus-containing Catalysts Open
The active site speciation of phosphorus-containing all-silica zeolites, P-zeosils, involves a dynamic distribution that is manipulated through controlled hydrolysis of the catalytic material. While water vapor is known to enhance the cata…

Enhanced Selectivity and Stability of Finned Ferrierite Catalysts in Butene Isomerization Open
Designing zeolite catalysts with improved mass transport properties is crucial for restrictive networks of either one‐ or two‐dimensional pore topologies. Here, we demonstrate the synthesis of finned ferrierite (FER), a commercial zeolite …
