Two kinds of well-aligned CuO nanostructured arrays composed of bundles of one-dimensional (1D) nanoribbons and densely packed two-dimensional (2D) nanosheets were selectively synthesized via a convenient one-step route by adjusting the reaction temperature. Detailed time-dependent evolutions of the morphology and phase were systematically studied and the formation of both CuO nanostructured arrays was shown to be due to oxidation→growth→dehydration and oxidation→dehydration→growth processes, respectively. The kinetically controlled nucleation and growth determined the final morphology of the CuO nanostructures. The photocatalytic activity of the as-prepared CuO nanostructured arrays was evaluated by the photodegradation of Rhodamine B(RhB) dye under simulated sunlight. This work provides a simple and economical route for the preparation of novel hierarchical nanomaterials which are expected to present a number of promising applications in various fields.
