The bimetallic catalyst Ru-Pt/AlOOH exhibited good catalytic performance in water for the hydrogenation of methyl propionate to I-propanol. The selectivity to I-propanol of 97.8% was obtained with a conversion of 89.1% at 453 K, 5 MPa for 6 h. The incorporation of Pt for the improvement of the catalystic activity was attributed to promoting the reduction of Ru3+ to Ru-0.
