Electro-catalytic activity of composites that they exhibited in the process is due to formation of metal particles (and their al-loys) by electrochemical reduction of metal cations in the polymer matrix. The main hydrogenation products are ethyl benzene and 1,4-diphenylbutane, the yields of which influence metal content in the studied composites. ER -
