采用简单的两步水热法在预处理过的铝膜基底上制备了ZnO纳米棒(NR)阵列微结构传感器。在碱性水热环境中,预处理后的基底上的Al转变为类水滑石的ZnAlCO3纳米片,作为ZnO NR阵列自组装过程的晶格匹配基底。对ZnO纳米棒的相纯度、形貌和结构的研究表明,在晶格匹配的ZnAlCO3纳米片上生长的ZnO纳米棒垂直排列,平均直径为80 nm,长度为2 μm。研究了ZnO NR阵列在不同工作温度和不同气体浓度范围内的乙醇敏感特性。结果显示,当传感器暴露于20 ppm乙醇时,其对乙醇的响应时间为2.8 s。
The microstructure sensor based on hierarchically ZnO nanorod (NR) arrays on the pretreated substrate with a thin film of aluminum (Al) has been achieved by using a simple two-step hydrothermal method. The Al on the pretreated substrate is transformed into hydrotalcite-like zinc aluminum carbonate (ZnAlCO3) nanosheets in the alkali hydrothermal environment, which acts as lattice-matched substrate for the self-assembly process of ZnO NR arrays. The investigations of phase purity, morphology, and structure of ZnO NRs reveal that the ZnO NRs grown on the lattice-matched ZnAlCO3nanosheets are vertically aligned with the average diameter of 80 nm and length of 2 μm. The ethanol sensing properties of the ZnO NR arrays are investigated at different operating temperatures and different gas concentration ranging. The results exhibit high response to ethanol with the response time of 2.8 s when the sensor is exposed to 20 ppm ethanol.
