摘要
提出了一种室温下于水相溶液中大规模合成Cu(OH)2纳米线的新方法.用X-射线粉末衍射(XRD)、透射电镜(TEM)和高分辨透射电镜(HRTEM)研究了所合成的Cu(OH)2纳米线的成分、形貌和结晶性.结果表明Cu(OH)2纳米线的尺寸分布均匀,平均直径约为9 nm,长度达数百微米.HRTEM研究表明Cu(OH)2纳米线是含有多晶成分的晶体.根据Cu(OH)2的结构特征和溶液中Cu2+与配位体之间的相互作用,对Cu(OH)2纳米线的形成机制给出合理的解释.
A new method for large-scale synthesis of Cu(OH)2 nanowires has been developed. The composition, morphology and crystallinity of the as-prepared Cu(OH)2 nanowires were characterized by XRD, TEM and HRTEM. TEM images indicated that the as-prepared Cu(OH)2 nanowires have an average diameter of about 9 nm with uniform diameter, and the length of up to several micrometers. HRTEM investigations indicated that the the as-prepared nanowires are composed of polycrystalline crystals. A rational explanation has been proposed for the growth of Cu(OH)2 nanowires based on the structural features of Cu(OH)2 and interaction between Cu^2+ and ligand in solution.
