Studies on the Growth Control of ZnO Nanostructures synthesized by the Chemical Method

ABSTRACT ZnO nanostructures were synthesized through a chemical method using different Zn precursors and hexamethylenetetramine (HMTA) at 90 °C. The effects of the reactants on the morphological evolution of ZnO nanorods were investigated. The samples were characterized by using XRD, SEM, EDX and BET. The hexagonal wurtzite phase of ZnO was confirmed by X-ray diffraction (XRD). The performed analysis indicated that different morphologies were obtained by changing the reactants.

摘要：本研究采用化学合成法，以不同锌前驱体与六亚甲基四胺（hexamethylenetetramine，HMTA）为原料，在90℃条件下合成了氧化锌纳米结构。考察了反应物对氧化锌纳米棒形貌演变的影响。采用X射线衍射（X-ray diffraction，XRD）、扫描电子显微镜（scanning electron microscopy，SEM）、能量色散X射线光谱（energy-dispersive X-ray spectroscopy，EDX）及BET比表面积分析法对样品进行了表征。经X射线衍射（XRD）证实，所得样品为六方纤锌矿相氧化锌。分析结果表明，改变反应物种类可获得不同形貌的产物。
