Figure ESM 1. Hydrogenation of cyclohexene by supported Rh NPs prepared by salt-impregnation route followed by metal reduction using two different methods: (black) hydrogen reduction in situ during the first hydrogenation reaction (cyclohexene, 75oC, 6 atm H2) and (red) reduction with NaBH4. Reaction conditions (solventless): Cyclohexene (14.6 mmol), catalyst (0.4 µmol of Rh), 75oC, 6 atm of H2. The inset shows the data fitting for determination of initial TOF.
