摘要
以氯化锌溶液和氨水为原料,采用水热合成方法,在铝片衬底上制备出多种氧化锌纳米结构.X射线衍射和扫描电镜分析结果表明:铝衬底上的氧化锌为纤锌矿结构,所得氧化锌结构包括六边形片状结构叠合而成的花形、棒状、管状结构等.随着反应时间的增加,产物中会同时出现大量棒状及管状氧化锌;pH值对氧化锌纳米结构的尺寸、形貌有较大的影响.
By using zinc chloride and ammonia as precursors,a hydrothermal process has been adopted to prepare ZnO nanostructures on Al substrates.X-ray diffraction(XRD) and scanning electron microscopy(SEM) results indicate that ZnO nanostructures grown on Al substrate crystallize in a wurtzite structure,and ZnO flower-like structures consisted of hexagonal nanosheets,rod-like structures,tube-like structures are obtained.As the increase of the reaction time,a great deal of rod-like and tube-like ZnO are obtained.The sizes and morphologies of the resulting ZnO nanostructures are influenced obviously by pH.
