Metal oxide nanoparticles are among the most widely used types of engineered nanomaterials.46
They are used in an extensive range of applications in various fields. Copper (II)-oxide nanoparticles (CuO-NPs) belong to the monoclinic structure system.
It has attracted particular interest because it is simple and shows a range of useful physical properties, such as superconductivity, electron correlation effects, relative stability, and low-cost preparation.55 CuO-NPs have multiple applications and can be utilized in batteries, supercapacitors, solar cells, gas sensors, biosensors, nanofluid, catalysis, photodetectors, energetic materials, field emissions, and superhydrophobic surfaces.
