Controlled Reduction of NiO Using Reactive Ball Milling

Nov 13, 2004· Controlled mechanochemical reduction of NiO has been carried out by room-temperature ball milling under H2 atmosphere. During the milling, a gradual conversion of NiO into Ni occurs, with no intermediate phases being formed. The amount of Ni and its crystallite size can be tuned by the ball-milling parameters, leading to the formation of Ni−NiO (metal−oxide) nanocomposites.
