Fabrication of sea urchin-like hierarchical porous SAPO-11 molecular sieves toward hydrogenation of lipid to jet fuel

Novel sea urchin-like hierarchical porous SAPO-11 molecular sieves were fabricated by adding CTAB after pre-crystallization. High isomer selectivity (78.2%) was observed for the sea urchin-like SAPO-11 loaded with Ni.

Visible-light-promoted olefinic trifluoromethylation of enamides with CF3SO2Na

A visible-light-promoted olefinic C–H trifluoromethylation of enamides was developed by employing cheap and stable Langlois’ reagent as the CF3 source, affording a series of β-CF3 enamides with high E-isomer selectivity.

Highly-efficient Ru/Al–SBA-15 catalysts with strong Lewis acid sites for the water-assisted hydrogenation of p-phthalic acid

A Ru/Al–SBA-15 catalyst with excess Lewis acid sites displayed excellent efficiency (100%), high cis-isomer selectivity (84%), and exceptional stability towards hydrogenation of p-phthalic acid in water.

Direct observation of the geometric isomer selectivity of a reaction controlled via adsorbed bromine

Methods to improve the specificity of stereoselective reactions are paramount to the viability of reaction-based processes.

Suppression of platinum sintering on Pt–M/ZSM-22 (M = Ce, La, and Re) catalyst for n-dodecane isomerization

Ce-modified Pt/ZSM-22 catalyst with slightly increased acidity and electron-deficient Pt exhibits improved isomer selectivity and sintering resistance of Pt in n-dodecane isomerization.

Combining ultra-high resolution ion mobility spectrometry with cryogenic IR spectroscopy for the study of biomolecular ions

We explore the capability of SLIM-based IMS for isomer selectivity in combination with cryogenic, messenger-tagging IR spectroscopy.
