“…It allows material scientists to control different parameters of the products such as shape, particle size, size distribution, and composition. Numerous methods such as thermal evaporation, sonochemical, sol-gel, hydrothermal, and electrochemical methods [ 2 , 11 – 15 ] and microwave irradiation approach [ 16 – 18 ] have been developed to synthesize CuO nanostructures with diverse morphologies, sizes, and dimensions using various chemical, physical, or chemistry physics combined strategies. This paper focuses only on direct solution methods to successfully prepare copper (II)-oxide (Cu=O) nanostructures with different sizes, shapes, some of their properties and different applications in daily life and technology.…”

Cupric oxide (CuO), having a narrow bandgap of 1.2 eV and a variety of chemophysical properties, is recently attractive in many fields such as energy conversion, optoelectronic devices, and catalyst. Compared with bulk material, the advanced properties of CuO nanostructures have been demonstrated; however, the fact that these materials cannot yet be produced in large scale is an obstacle to realize the potential applications of this material. In this respect, chemical methods seem to be efficient synthesis processes which yield not only large quantities but also high quality and advanced material properties. In this paper, the effect of some general factors on the morphology and properties of CuO nanomaterials prepared by solution methods will be overviewed. In terms of advanced nanostructure synthesis, microwave method in which copper hydroxide nanostructures are produced in the precursor solution and sequentially transformed by microwave into CuO may be considered as a promising method to explore in the near future. This method produces not only large quantities of nanoproducts in a short reaction time of several minutes, but also high quality materials with advanced properties. A brief review on some unique properties and applications of CuO nanostructures will be also presented.

“…Moreover, CuO nanoparticles reveal a great potential for use as antimicrobial agents [8]. Several methods like thermal evaporation, sonochemical [9], sol-gel [10], hydrothermal [11], and electrochemical procedures [12] and microwave irradiation method [13] have all been used to produce copper oxide nanostructures with varied morphologies, dimensions and sizes using different physical, chemical, or combined physics and chemistry strategies. In contrast, nanoparticles synthesized using the above mentioned methods are suffering from drawbacks including, high reagent costs, hazardous reaction conditions, longer processing time and a time-consuming process to separate nanoparticles.…”

Copper oxide nanoparticles are essential technology materials that are utilized as catalysts in the chemical industry, as well as in photonic and electronic devices and medical applications. Due to their applications in advanced technologies, we have concentrated on the production of CuO nanoparticles using enhanced, cost-effective, and environmentally friendly synthetic techniques. In this paper, we have presented a green synthesis technique to successfully synthesis copper oxide nanoparticles (CuO NPs) utilizing copper (II) sulfate pentahydrate (CuSO4.5H2O) as precursor salt and Mentha Piperita leaf extract as a reducing and stabilizing agent during the synthesis process. The precursor salt solution and reducing agent were mixed in a 1:1 volume ratio at 50 °C. The CuO NPs synthesized were confirmed by the characteristics Surface Plasmon Resonance (SPR) peak in the UV-visible region. Also, the optical direct band gap energy of the CuO NPs determined from the Tauc plot was 3.26 eV. The FTIR spectrum analysis confirmed existence of functional groups of polyphenols from Mentha piperita L. leaf extract, which are responsible for the reduction of Cu2+ ions and effective stabilization of CuO NPs. All the peaks observed in the XRD pattern revealed the production of CuO NPs having monoclinic structure with an average crystallite size of 42.51 nm. The surface morphology of the CuO nanoparticles was detected using SEM analysis. Further, the synthesis mechanism of CuO NPs has also been investigated.

“…Therefore, many techniques including hydrothermal [6], microwave [7], sol-gel [8], sonochemical [9], and double-hydroxide treatment [1] methods, have been developed to prepare CuO nanomaterials with versatile performances. The CuO micro-/ nanostructures with various morphologies have been obtained so far, such as nanowire [6], flowerlike [1], dandelion-like [10], honeycomb-like [11], urchin-like [12], and umbel-like [13] nanostructures.…”
