摘要: 运用水热法合成六方纤锌矿ZnO纳米棒,在ZnO纳米棒表面水热生长SnO,获得了表面疏松的ZnO/SnO复合纳米棒材料。运用X射线粉末衍射(XRD)、透射电子显微镜(TEM)、扫描电子显微镜(SEM)、电子能谱(EDS)等手段表征了该材料的形貌和组成。BET氮吸附测试表明其表面疏松结构具有11.38 m2/g的比表面积。气敏实验证明了该材料对甲醛气体具有百万分率浓度级检测灵敏度,对于开发甲醛传感材料具有理论意义和潜在应用价值。

Abstract: The Porous ZnO/SnO composite nanorods were fabricated through hydrothermal method. The prepared hexagonal wurtzite structure ZnO nanorods were coated by SnO as porous shells. The structure and morphology of the resultant products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and energy dispersive spectrdmeter (EDS). The BET nitrogen adsorption—desorption technique indicated the as-prepared composite nanorods with 11.38 m2/g surface area. The gas sensing properties of the as-prepared ZnO/SnO composite nanorods were investigated. The composite nanorods exhibited a superior gas sensing performance toward ppm level formaldehyde vapor, implying promising applications in detecting toxic volatile organic compounds (VOCs).

Key words: SnO, gas sensor, composite nanorod, ZnO
