Abstract: ZnO@CeO2 coaxial nanocables were successfully synthesized by coaxial electrospinning using cerous nitrate, zinc nitrate, polyvinyl pyrrolidone, N, N-dimethylformamide, glycerin and chloroform as starting materials. The samples were characterized by thermogravimetry and differential thermal analysis, X-ray diffractometry, scanning electron microscopy,transmission electron microscopy and energy dispersive spectroscopy techniques. The results show that ZnO@CeO2 coaxial nanocable with a diameter of ca.90 nm,core diameter of ca.60 nm and shell thickness of ca.15 nm. The nanocables has a core of crystalline ZnO and a shell of crystalline CeO2. The length of the ZnO@CeO2 nanocables is greater than 300 μm. The formation mechanism of the ZnO@CeO2 nanocables is preliminarily investigated.
