| Abstract: Nano-NiO powder was prepared by thermal decomposition of the precursor of NiC2O4·2H2O obtained via Ni(NO3)2·6H2O and H2C2O4·2H2O reacting in ethanol solvent. IR and TGA-DTA indicate physisorption and chem- isorption ethanol co-exist in the precursor. XRD suggests the obtained cubic NiO is stable below 700 ℃. TEM shows the as-calcined NiO at 400 ℃ for 2 hours was of narrow distribution, weak agglomeration and small particle size (average 8 nm). The reason for weak agglomeration was explained. |
