Further the growth evolution of pyramidal Cu nanoparticles was observed for the first time. We believe that our method might open new possibilities for fabricating nanomaterials of non-noble transition metals with various novel architectures which can then potentially be utilized in applications such as biosensors catalysis photovoltaic cells and electronic nanodevices.
