Nickel hydroxide experimental method

In these experimental conditions the precipitation of cj>, and the reduction of Co(II) and Ni(II) species occur simultaneously, and then < >, is not able to act as a reservoir for these species. Thus, sodium hydroxide was added in a large excess to the reaction medium in the synthesis of CoNi monodisperse particles in order to provide an excess of hydroxide ions (8,30). This method can be extended to obtain nickel-noble metal alloys. Thus PVP-protected Ni-Pd colloids were obtained by Toshima et al. (31) for different Ni/Pd ratios.
