Isoprene hydrogenation was investigated on Pd-Fe/alumina catalysts in
the liquid phase. Iron added by a controlled surface reaction (CSR) pr
omotes the activity of small palladium particles while the opposite ef
fect is generally observed on catalysts prepared by coimpregnation or
successive impregnations of the metal precursor salts. Iron introduced
by CSR would be deposited on the surface of palladium particles while
the other preparation techniques would lead to alloy formation, (C) 1
