Bimetallic Pd-Au nanoparticles immobilized on POPAM-grafted MWCNTs hybrid materials as a heterogeneous catalyst for the selective hydrogenation of alkenes

Hydrogenation is one of the industrially important catalytic reactions. Hydrocarbons are activated by oxidation or hydrogenation reactions that are useful methods in thecommercial exploitation of fossil fuels [1]. Carbon nanotubes (CNTs) are attractive solid supports for heterogeneous catalysts due to their unique properties andsurface structures. Making complexes of the metal ions and then reducing these ions was used to prepare dendrimerencapsulatednanoparticles. The resulting immobilized nanoparticles are nearly monodisperse in size and stable against aggregation [2].Polypropylene amine dendrimers (POPAM) is one of the most frequently studied branched species and there are numerousreports on them
