摘要
The influences of pyrolytic conditions,including temperature,time,the flow ra te of air,and the heating rate,on the morphology,average size and specific su rface area of the NiO particles were investigated,and the composition and morph ologies of the products were characterized by using of XRD,SEM and BET. It is f ound that fibrous NiO particles were produced under the optimal conditions. A su itable range of pH for preparing dispersive precursors was chosen according to a nalysis of zeta potential. Based on the observations of NiO precursors growth an d SEM morphology of the precursor,the oriented attachment was proposed for the well-aligned growth of the NiO precursor fibres. The final product NiO inherits the morphology of the precursor.
