Abstract

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.
