Ni/NiFe2O4 composites have been successfully prepared by calcination at 400°C in air of the mixture K3[Fe(ox) 3]·2.5H2O and NiCl2·6H 2O with a molar ratio of 0.7-2. The products are featured by the Ni crystallite size of 15-34nm, BET surface area of 23-41m2/g and variable Ni loadings. TGA and FTIR results indicate in situ generation of CO molecules from decomposition of K3[Fe(ox)3]·2. 5H2O. These in situ generated CO molecules account for the formation of Ni nanoparticles by reduction of Ni(II) ions.
