Abstract
CuO nanodendrites have been synthesized by a simple and novel hydrothermal method.Their morphology, structure, and composition have been also characterized. The resultsshow that an as-prepared nanodendrite is composed of a main branch-like nanorod nearupon a micrometre in length and about 100 nm in diameter and the sub-branch nanorodsseveral hundred nanometres in length and 20–60 nm in diameter. The dendrite-likeCuO nanostructures are of monoclinic phase and single crystalline in nature.The investigation of the hydrothermal process assisted by different quantities ofethylene glycol (EG) indicates that EG plays a critical role in the formation ofdendrite-like CuO nanostructures. A possible mechanism for the formation of such CuOnanostructures is discussed. Furthermore, the correlation between the optical spectrumand the different morphologies of copper oxides nanomaterials is also discussed.
