摘要

One-dimensional (1D) CuO nanostructures with nanoribbons, scroll-like structure, arrays of CuO nanoparticles and nanorod-like morphologies respectively, have been successfully prepared using the single-crystalline Cu_2(OH)_2CO_3 nanoribbons as precursors for sacrifice-template via heat-treatments. The series of morphologies images for decomposition kinetics process of Cu_2(OH)_2CO_3 nanoribbons as heat-treatment temperature increased are presented in this work. The result demonstrates that the morphologies of the 1D CuO nanostructures obtained are mainly due to the ribbon-like shape of the precursors. The morphologies of CuO nanostructures also strongly depend on the heat-treatment conditions. At relatively low heat-treatment temperature and heating rate, the morphological features of the precursor can be preserved well, while arrays of CuO nanoparticles can be obtained at higher heating rate and CuO rod-like shape can be prepared with increasing heat-treatment temperature.
