Description
Summary:[Display omitted] •Li-functionalized alumina is obtained by surface organometallic chemistry on oxide.•Supported PtSn nanoparticles are prepared by surface organometallic chemistry on metal.•The influence of each additives has been determined.•2,3-dimethylbutane can be 100% dehydrogenated to hexenes, mainly 2,3-dimethylbutenes. 2,3-dimethylbutane is selectively converted into 2,3-dimethylbutenes at 500 °C under hydrogen or at 390 °C under nitrogen in the presence of bimetallic catalysts Pt-Sn/Li-Al2O3. The high stability of the catalyst along the reaction is obtained by selective modification of the Pt/Li-Al2O3 catalyst using Surface Organometallic Chemistry (SOMC).
