The poly(styrene-co-acrylonitrile) supported palladium catalyst bearing a nano-fibrous morphology was prepared via electrospinning technique

and the catalyst was characterized by IR

SEM

TEM and XPS.The nano-fiber supported catalyst has high activity and good recycling property for hydrogenation of α-olefin at room temperature under 101.3 Pa.hydrogen pressure.In addition

it was found that the hydrogenation reaction of α-hexene was accompanied with the isomerization reaction.The experimental results show that the yield of the α-hexene to hexane catalyzed by the nano-fiber supported palladium catalyst was 4.7 times higher than that of PdCl2/γ-Al2O3 catalyst.The hydrogenation of α-tetradecylene

cyclohexene

nitrobenzol and styrene by the nano-fiber supported palladium catalyst was also studied

the selectivity to primary products of the hydrogenation of cyclohexene

nitrobenzol and styrene was 100%.
