We have demonstrated an interesting approach for the one-pot synthesis of cupric oxide (CuO) nanourchins with sub-100 nm through a sequential dissolution-precipitation process in a water/ethanol system. The first stage produces a precursory crystal [Cu7Cl4(OH)10H2O] that is transformed into monoclinic CuO nanourchins during the following stage. Water is a required reactant for the morphology-controlled growth of different CuO nanostructures. When evaluated for their nonenzymatic glucose-sensing properties, these CuO nanourchins manifest higher sensitivity. Significantly, this water-dependent precursor transformation method may be widely used to effectively control the growth of other metal oxide nanostructures.
我们展示了一种有趣的一锅法合成氧化铜（CuO）纳米角锥的方法，通过在水/乙醇体系中的顺序溶解-沉淀过程，得到亚 100nm 的 CuO 纳米角锥。第一阶段生成前驱体晶[Cu7Cl4(OH)10H2O]，在随后的阶段转化为单斜晶系的 CuO 纳米角锥。水是控制不同 CuO 纳米结构形态生长的必需反应物。当评估其非酶葡萄糖传感性能时，这些 CuO 纳米角锥表现出更高的灵敏度。重要的是，这种依赖于水的前体转化方法可能被广泛用于有效地控制其他金属氧化物纳米结构的生长。
