Routes to nano-phase nickel in the forms of highly porous sponges and dense films have been developed.Nickel acetate and nitrate were mixed with triethanolamine and methanol, and evaporated to a concentrated liquid.Heat-treatment at 10±C/min to 170±C under N2 atmosphere yielded a highly porous sponge consisting of <10 nmsized Ni crystallites. Deposition of a 1 M nickel precursor solution on polycrystalline Al2O3, SnO2 : F coated glassor titanium substrates spinning at 2700 rpm, followed by heat-treatment at 10±C/min to 400±C yielded smooth anddense nickel films consisting of 3–5 nm sized crystallites. The precursor concentrate was studied by FT-IR andthe phase development on heat-treatment was studied by thermogravimetric analysis, powder X-ray diffraction,scanning and transmission electron microscopy.
