Abstract: Manifold mixed precursors were prepared with Ni(CH3COO)2·4H2O, Co(CH3COO)2·4H2O, H2C2O4·2H2O and different surfactants by solid state reaction at room temperature; then they were put into a bain-marie to keep 2d at 60℃. After these precursors analyzed by TG-DTA, and decomposed at 610℃, the phase and topography of the thermolysis products were characterized by XRD, SEM. The nanometer composite oxide NiCo2O4 with different topography was obtained. The experimental results show that these surfactants act as soft-templates, they have evident effect on topography of products.

Key words: NiCo2O4, surfactant, solid state reaction, topography
