| 1. A method of making nanometer size particles of nickel or nickel oxide, or particles having a core of nickel enclosed in
a shell of nickel oxide, the method comprising:
dissolving a nickel salt in a glycerol containing solvent;
precipitating a complex of nickel and glycerol from the solution, filtering the precipitate, washing the precipitate, and
drying the precipitate; and thereafter
heating the precipitate in an atmosphere and at a temperature and for a time selected to decompose the nickel-glycerol complex
and to produce particles of nickel, or nickel oxide, or particles having a core of nickel enclosed in a shell of nickel oxide.
