Preparation of NiO Nanorods by a Solid State Reaction at Low Temperatures under an Ultrasonic Airflow
Abstract:
The nanoparticles of NiO precursor were prepared by a low temperature solid state reaction under ultrasonic airflow.The precursor was converted into NiO nanorods after annealing at 650~900℃ in a molten salt medium.The structure and morphology of NiO precursor and nanorods were investigated by XRD,SEM and TEM technologies.The results indicated that the prepared precursor was spheric particles with a diameter of about 25 nm,and grew gradually to NiO nanorods with a diameter of about 300 nm and a length of several micrometers along with rising calcinging temperatures.The key factor in the process for the grwoth of NiO nanorods is the molten salt medium.
