Sustainable Development of Copper Oxide Nanoparticles for Automotive Applications

Abstract

Copper oxide nanoparticles have sparked widespread interest due to their outstanding characteristics, making them intriguing candidates for a variety of applications, including bio-lubricants. This work investigates the synthesis, characterization, and prospective uses of CuO NPs in the context of sustainable technologies, specifically in the automobile industry. In the present work, CuO is synthesized through chemical precipitation methods followed by a calcination process. The calcination process is conducted at various temperature levels, forming pure copper oxide at a temperature of 1000 °C. The properties of the synthesized nanoparticles were analyzed by a field emission scanning electron microscope, which shows the spherical structure of CuO. X-ray diffraction declares the improved crystal structure of the phase analysis after calcination, and the Fourier transform infrared spectroscopy shows the purity of CuO after calcination at 1000 °C. The economic viability of the suggested synthesis technique was evaluated, revealing a production cost of INR 170.6 per gram, which is much cheaper than the current market price. This shows that the suggested technique might produce CuO NPs on a large scale at a low cost.
