Copper oxide is a semiconductor material and has a characteristic plenitude of beginning material, copper. It is non-harmful and you can easily get it by the oxidation of Cu. Copper oxide is one of the critical metal oxides which has pulled in late research due to its ease, copious accessibly and curious properties.


Importance of Nanoparticles:

Nanofluids have been found to have improved thermo physical properties such as warm conductivity, warm diffusivity, and consistency. It has exhibited incredible potential applications in many fields like microelectronics, transportation, assembling and much more.

Copper oxide nano particles are a fascinating class of material having multi functional properties with promising applications in batteries, attractive capacity media, sun oriented vitality, and superconductors.

How to prepare Copper oxide nano particles?

Copper oxide nanofluid has been set up by single-step wet compound precipitation strategy. The arrangement of nanoparticles is done by reducing copper chloride with sodium hydroxide. Here sodium hydroxide is used as a reducing agent for de ionizing water as a base liquid. During its preparation, the temperature effect can be seen on the size, band gap and the crystalline nature of the particle. Temperature effect can be studied with the help of UV-Spectroscopy, powder X-Ray Diffraction (XRD) and Scanning Electron Microscopy.
