摘要
文章报道一种新的Cu(OH)2纳米带阵列合成方法,即气体-溶液-固体法。这种方法主要特点是把铜片置于氨水的液面上,使铜片基板表面有氧气、氨水和铜参与反应,最终在铜片基板上生长出Cu(OH)2纳米带阵列。Cu(OH)2纳米带的尺寸可以通过控制氨水的浓度进行调节,即氨水浓度降低,Cu(OH)2纳米带的尺寸也变小了;而且Cu(OH)2在一定温度下可以脱水转变成为CuO纳米带;最后研究了Cu(OH)2和CuO纳米带阵列的生长机理。
A simple gas-solution-solid method had been successfully developed to prepare Cu（OH）2 nanoribbon arrays on Cu substrates.The method consists of putting Cu foils above the ammonia solution for about 24 hours to obtain Cu（OH）2 nanoribbon arrays.The sizes of Cu（OH）2 nanoribbons were determined by the concentrations of ammonia solutions.Lowing the concentrations of ammonia solutions resulted in small sizes of Cu（OH）2 nanoribbons.Finally,Cu（OH）2 nanoribbons were transformed into CuO nanoribbons by heating at 100 ℃ for 4 hours and the growth mechanism of the nanoribbons was also studied.
