Nanostructured materials have extensive variety of applications owing to their nanosize dependent physicochemical properties. A greener production of Copper oxide (CuO) nanoparticles without spending toxic and expensive organic solvents have been demonstrated by mean of Aloe-vera leaf extract compared with CuO synthesized by chemical mean. The amorphous characteristics, nanosize particles (~15 nm) and particular monoclinic phase of CuO, confirmed by XRD has been achieved by greener synthesis. Transmission Electron Microscope (TEM) revealed the spherical shape with uniform distribution of as-synthesized nanoparticles. Further, vibrational band at 473 cm-1and 624 cm-1in Fourier Transform Infrared Spectroscopy (FTIR) confirms the CuO and Cu2O oxides formation respectively. The CuO nanoparticles synthesized by Aloe-vera leaves exhibited 50 % higher thermal conductivity as compared to chemically synthesized CuO nanoparticles. This approach for the synthesis of CuO nanoparticles could be beneficial for various application because of it easy, eco-friendly and cost-effective synthesis procedure.
