在无底物和无表面活性剂的条件下,首次采用简单的一步水热方法合成了一种新型的sno2纳米棒阵列结构。采用x射线衍射谱(XRD)、扫描电镜(SEM)、透射电镜(TEM)和高分辨率透射电镜(HRTEM)对sno2纳米棒阵列的形貌和相结构进行了表征。结果表明:该纳米棒阵列由两层直径为25nm、高度为200 ~ 300nm的金红石结构sno2纳米棒组成;两层sno2纳米棒生长方向相反。本文提出了一种合理的sno2纳米棒阵列形成机制。
A novel structure of SnO2nanorods arrays had been firstly synthesized by a facile one-step hydrothermal route in the absence of substrates and without any surfactants. X-ray diffraction spectra (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM) were used to examine the morphology and phase structure of SnO2nanorods arrays. The results show that the nanorods array is built by two layers of rutile structure SnO2nanorods with the diameter of 25nm and the height of 200–300nm. The two layers of SnO2nanorods are in the opposite growth direction. A plausible formation mechanism of SnO2nanorods arrays was proposed in this paper.
