中文摘要：

通过化学气相沉积法（CVD）合成出梳状分等级结构的ZnO纳米带，使用场发射扫描电子显微镜（SEM）和X射线衍射仪（XRD）对材料组成和结构进行了分析。利用这种材料制备了厚膜型管式气敏元件，并采用静态配气测试系统进行了气敏性能测试。测试结果表明，工作温度大约为225℃时，这种结构的材料对有机挥发性气体（volatileorganiccompounds，VOC）具有极快的响应和恢复速度，响应时间为2s，恢复时间为3s。最后分析了材料结构对气敏性能的影响。

英文摘要：

The brush-like hierarchical ZnO nanobelts were successfully synthesized by a simple chemical vapor deposition method. The morphology and the structure were investigated by scanning electron microscopy and X- ray diffraction. Thick film type tubular device was prepared by this material and gas sensing properties of the sensor devices were measured in a static apparatus. The sensor performance of the brush-like hierarchical ZnO nanobelts was measured for volatile organic compounds at 225 ℃. It was found that the nanostructures exhibited excellent volatile organic compounds sensing properties, especially quite rapidly response and recovery. The re- sponse and recovery time are 2 and 3s. Furthermore, the effect of material structure on sensing properties was also investigated in this paper.
