∼100% selectivity to 3-aminoacetophenone could be obtained from 3-nitroacetophenone hydrogenation over the Pt/TiO2.
The catalytic activity of the Pt/TiO2 for 3-nitroacetophenone hydrogenation is almost 45 times higher than that of the Rh/SiO2.
The results presented here highlight the great potential of the Pt/TiO2 catalyst in the selective hydrogenation of nitroacetophenones on a large scale.
