High Dispersity

Ag nanoparticles decorated N-doped carbon black with different Ag content was synthesized via a straightforward method. The catalysts have been conducted in the catalytic hydrogenation of nitrophenols in the presence of sodium borohydride. The results show that Ag4/NCB possesses the highest catalytic activity for the catalytic hydrogenation of [Formula: see text]-nitrophenol ([Formula: see text]-NP) to [Formula: see text]-aminophenol ([Formula: see text]-AP). The significant enhancement in catalytic activity can be attributed to the high dispersity and smaller size of Ag nanoparticles, and remarkable synergistic effect of the combination of Ag nanoparticles and N-doped carbon black.
