以 Zn(OH)(4)(2-) 水溶液为原料，在 DAB 存在下，通过简单的低温水热工艺以高产率（约 85%）制备 ZnO 纳米棒，CTAB 充当结构导向器，并且不需要煅烧过程。通过X射线衍射(XRD)、扫描电子显微镜(SEM)和透射电子显微镜(TEM)对制备的ZnO纳米棒的形貌和晶体结构进行了表征。然后使用氧化锌纳米棒构建气体传感器，用于不同工作温度下的乙醇检测。所制备的ZnO纳米棒气体传感器对乙醇表现出高、可逆和快速的响应，表明其作为检测乙醇的气体传感器的潜在应用。 (C) 2011 Elsevier B.V. 保留所有权利。
ZnO nanorods were fabricated by a simple low-temperature hydrothermal process in high yield (about 85%), starting with Zn(OH)(4)(2-) aqueous solution in the presence of DAB, the CTAB serving as a structure director, and no calcination process was needed. The morphology and crystal structure of the prepared ZnO nanorods were characterized by X-ray diffraction (XRD), Scanning electron microscope (SEM) and Transmission electron microscope (TEM). The ZnO nanorods were then used to construct a gas sensor for ethanol detection at different operating temperature. The as-prepared ZnO nanorod gas sensor exhibited a high, reversible and fast response to ethanol, indicating its potential application as a gas sensor to detect ethanol. (C) 2011 Elsevier B.V.
