International audience; Herein, we describe an efficient and recyclable catalytic system based on metal triflates capable of converting highly concentrated feeds of furfuryl alcohol (30-40 wt %) to alkyl levulinates in excellent yields (>90%). This c

Fluorine-implanted titanosilicate Ti-MWW, with greatly enhanced catalytic performance in the liquid-phase epoxidation of ethylene with aqueous hydrogen peroxide, has been post-synthesized by fluorinating conventional Ti-MWW with NH4F. The effects of

In this paper, we report a green and selective route for the direct oxidation of alcohol ethoxylates (AEOs) into alkyl ether carboxylic acids over supported noble metal catalysts using H 2 O 2 as an oxidant in the presence of a base. The catalytic pe

SBA‐15 catalysts doped with variable aluminum amounts were prepared through a facile evaporation‐induced self‐assembly process. The textural properties and acidity of the catalysts could be tuned simply by varying the aluminum content. The gene
