Temperature-controlled self-assembled synthesis of CuO, Cu_2O and Cu nanoparticles through a single-precursor route

摘要

In this paper, we report on the synthesis of CuO, Cu_2O and Cu nanoparticles through a single-precursor route by controlling the growth temperature. CuO and Cu_2O nanoparticles have nanoporous structural configurations composed of a large number of primary particles. According to the difference between the crystal planes, we proposed the possible growth mechanisms of CuO, Cu_2O and Cu nanoparticles. Selective adsorption of oleylamine on various crystal planes may play an important role in the growth process. The understanding of this self-assembling process will help us to develop reliable and reproducible methods to synthesis other three dimensional nanostructured architectures and increase the knowledge of self-assembly.
