Abstract:
A various of metal oxide nanomaterials were synthesized by arc-electrodeposition method in NaCl aqueous electrolyte, with different metal electrodes, under the voltage of 100V. The morphologies of the obtained nanomaterials were controlled successfully. The products were characterized by X-ray diffraction (XRD) and the XRD patterns were recorded with a Rigaku D/max-γA rotating anode X-ray diffractometer in the 2θrange 10o70o. The morphology and particle size of the products were investigated by transmission electron microscopy (TEM) and the TEM analyses were taken with aHitachi H-800 transmission electron microscope. From the results of XRD and TEM, it is obvious that different metal oxide products had different morphologies. The produced Fe3O4is spherical mixed by a few of rod-like product, ZnO is elliptic,γ-AlOOH is acicular and Mg(OH)2is acicular. It is apparent that the morphologies of the products obtained corresponding to different metal electrodes are greatly different from each other, under the same other experimental conditions. One can conclude from the TEM results that the products with different phase structures have different growth habits under the same experimental conditions, for example, the formation of tube-like Mg(OH)2may be closely related to the hexahedral structure of Mg(OH)2. It is very necessary to further study the relationship between the morphology of the product and the experimental conditions, especially the conditions for the formation of nanotubes.

摘要:
以不同种类的金属丝为电极,采用交流电沉积的方法在液相水溶液中制备了多种金属氧化物纳米材料,并对其形貌进行了控制.由XRD和TEM分析结果表明,在相同的NaCl电解质水溶液中,不同的金属电极对应的不同金属氧化物纳米产物具有明显不同的形貌.
