室温液相合成Cu（OH）2纳米线及其结构

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9nm，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Cu^2＋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．

Room-Temperature Synthesis of Cu(OH)2 Nanowires and Their Structural Features

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.
