Highly selective one-step hydrogenation of nitrobenzene to cyclohexylamine over the supported 10% Ni/carbon catalysts doped with 3‰ Rh

The catalyst 3‰ Rh–10% Ni/CSC exhibits an excellent performance to achieve 100 mol% conversion of nitrobenzene and 91.6% selectivity of fully-hydrogenated cyclohexylamine under conditions of 3.5 MPa H₂ and 140 °C.
