摘要
采用水热法和后继热处理法制备二氧化钛（TiO2）纳米带，然后通过液相合成法在纳米带表面组装了氧化锌（ZnO）纳米结构，制备了ZnO@TiO2纳米带表面异质结构。利用X射线衍射（XRD）、扫描电镜（SEM）、透射电镜（TEM）等手段对异质结构进行了表征。所制得的产物是TiO2的纳米带表面组装了ZnO纳米花：TiO2纳米带的宽度为50～200nm，长度达到几十微米，而ZnO异质结呈花状，长为500nm的骨苞上长有200nm左右的花瓣。本文还讨论了ZnO@TiO2表面异质结构的形成机制。
On the basis of the TiO2 nanobehs made via hydrothermal method and post heat-treatment, zinc oxide@ titanium dioxide nanobelts of heterostructure were successfully synthesized through the liquid phase method. The nanobehs were characterized by different techniques, such as X-ray powder diffractometer （XRD）, scanning electron microscopy （SEM）, and transmission electron microscopy （TEM）. The products were ZnO nanoflowers self-assembled on the surface of titanium dioxide nanobelts. The nanobehs were 50 ～ 200 nm in width and several tens micrometers in length, while the ZnO of heterostructure was a bud with 500 nm in length had the petals of about 200 nm. The formation mechanisms of ZnO @ TiO2 nanobelts heterostructure mentioned above were also discussed briefly.
