摘要：

Flower-like NiO powders with nano-architectures, self-assembled nano-sheets, were synthesized using Ni (NO(3))(2)center dot 4H(2)O and urea in mix solvents of ethanol and water by homogeneous precipitation. XRD patterns showed that the NiO powders were of hexagonal structure. FESEM and TEM confirmed that the average diameter of the flower-like NiO was 10 mu m, and the ultra-thin nano-sheets had micro-porous structure, with the thickness less than 100nm and the size of 2 mu mx3 mu m. Specific surface area (BET) was around 130.92m(2)/g.
