摘要：

Nanocrystalline nickel oxide (NiO) powder was prepared by thermal decomposition of the precursor of NiC2O4. 2H(2)O obtained via the reaction between Ni(NO3). 6H(2)O and H2C2O4. 2H(2)O in ethanol solvent. The products were characterized using X-ray diffraction, infrared absorption spectroscopy, thermogravimetric analysis-differential thermal analysis, and transmission electron microscopy. The particle sizes of the as-calcined NiO increased with increase in temperature. The as-calcined NiO at 400 degreesC for 1 h was of narrow distribution, weak agglomeration and small particle size (average = 8 nm). The reason for weak agglomeration was explained.
