摘　　要：Using the idea of material design and the design of reaction system and conditions,quasi-one-dimensional nano-materials with ribbon-like structure were successfully prepared.Nickel tartrate nanobelts were prepared by a sol-precipitation route,using nickel chloride hexahydrate and tartaric acid as raw materials,and using ammonium hydroxide as pH value modifier.Nickel nanobelts with smooth surface were prepared by a thermal-decomposition route at about 355℃for about 30 minutes,in CO_(2) atmosphere,using nickel tartrate nanobelts as precursor.The analyses of atomic absorption spectrometry(AAS),organic elemental analyzer(OEA),infrared spectroscopy(IR)and ultraviolet-visible spectroscopy(UV-Vis)indicate that the products as-prepared is nickel tartrate,which has octahedral configuration of co-ordination of nickel atoms.The images of scanning electron microscopy(SEM)indicate that the morphology of nickel tartrate as-prepared is an obvious belt structure with clear and smooth surface.The images of SEM also indicate that the nickel nanobelts have clear and smooth surface.The nickel nanobelts are about tens of micrometers in length,tens of nanometers in thickness,and 100-200 nanometers in width.
