Two kinds of core/shell type [email protected]2O3 and [email protected]2 nanocables were prepared by the chemical reduction of AgNO3 as Ag core and the hydrolysis of metal alkoxides as shell. The SEM, TEM, XRD, FTIR and UV-Vis analysis were used to characterize the microstructures and chemical characteristics of [email protected] x O y nanocables. Microstructure analysis by SEM and TEM showed that both of the obtained [email protected]2O3 and [email protected]2 nanocables have typical core–shell structure. Transmission electron microscopy measurements revealed that the diameter of Ag is about 35 nm and the shell thickness is 5 nm. FT-IR patterns proved that Ag core and M x O y shell has corresponding to a diffraction peak and the absorption peak of the vibration. XRD patterns showed the presence of the noble metal (Ag) and the differences of the diffraction peak intensity, which indicated the presence of M x O y shell. UV-Vis spectra showed that the plasma resonance absorption of [email protected] x O y nanocables has a weak red shift, due to the scattering effect of the M x O y shell. These [email protected] x O y core/shell nanocables will gain increasing applications in nanoscale electronic, optoelectronic, and sensing devices.
