Controlled mechanochemical reduction of NiO has been carried out by roomtemperature 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 ballmilling parameters, leading to the formation of Ni−NiO (metal−oxide) nanocomposites.
