Hydrogenation of nitrophenols catalyzed by carbon black-supported nickel nanoparticles under mild conditions
TL;DR: In this paper, a carbon black supported nano-Ni catalyst was used for hydrogenation of nitrophenols even at 30 degrees C. The high performance obtained by the Ni-based catalyst can be attributed to the specific characteristics of the nanostructure of the catalyst and the synergistic effect of nanoNi and carbon black, including plenty of oxygen-containing groups of carbon black for anchoring Ni atoms.
