Over Pd/Fe bimetallic catalyst, o-nitrochlorobenzene (o-NCB), at a concentration of 20 mg/L in aqueous solutions, is rapidly converted to o-chloroaniline (o-CAN) first, and then quickly dechlorinated to aniline(AN) and Cl-, without other intermediate reaction products. The aminated and dechlorinated reactions
