[Display omitted] Iron-modified platinum bimetallic system, 1% Pt–1% Fe/SiO2, provides selective liquid-phase hydrogenation of phenylacetylene into styrene at 70°C and 5 atm. This effect is attributed to the electron enrichment of the Pt surface atoms due to a charge transfer from Fe to Pt or contac...
