Cupric oxide (CuO), having a narrow bandgap of 1.2 eV and various thermophysical properties, is recently attractive in many fields, such as energy conversion, optoelectronic devices, and catalysts. Compared with bulk material, the advanced properties of CuO nanostructures have been demonstrated; however, the fact that these materials cannot yet be produced on a large scale is an obstacle to realizing the potential applications of this material. In this respect, chemical methods are efficient synthesis processes that yield significant quantities and high-quality and advanced material properties. This paper will overview the effect of some general factors on the morphology and properties of CuO nanomaterials prepared by solution methods. Regarding advanced nanostructure synthesis, the microwave method in which copper hydroxide nanostructures are produced in the precursor solution and sequentially transformed by microwave into CuO is a promising method to explore shortly. This method has large quantities of nano products in a short reaction time of several minutes and high-quality materials with advanced properties. A brief review of some unique properties and applications of CuO nanostructures will also be presented. In recent years, nanostructures of transition metal oxides have gained significant attention from material scientists and engineers due to their different properties compared with the corresponding bulk counterparts, providing promising applications in various technology fields. The preparation of high-quality nanostructures of defined, controllable size and morphology is a critical requirement to develop nanodevices or other different applications for catalysts, sensing, pharmacy, etc. If you are looking for high quality, high purity, and cost-effective Copper Oxide, or if you require the latest price of Copper Oxide, please feel free to email contact mis-asia.
