2. Synthesis of CuO nanostructures
The development of synthetic methods has been widely accepted as an area of fundamental importance to the understanding and application of nanoscale materials. It allows scientists to modulate different parameters such as morphology, particle size, size distributions, and composition. Numerous methods have been recently developed to synthesize various CuO nanostructures with diverse morphologies, sizes, and dimensions using various chemical and physical strategies. In this review, we present the most common synthetic strategies and associated mechanisms for tuning the morphology, size, and structure of the CuO nanostructures along with the studies of the effects of these parameters on the chemical and physical properties of the synthesized nanostructures.
