Modulation of synthetic parameters of cobalt nanoparticles: TEM, EDS, spectral and thermal studies

The study focuses on the modulation of synthetic parameters in order to influence the size, structure, composition and arrangement of nanoparticles of cobalt. Cobalt nanoparticles were synthesized by ethanolic solution of benzildiethylenetriamine in cobalt nitrate solution at 60 °C with stirring and refluxing leads to nanoparticles of cobalt. The morphology and structure of the synthesized nanoparticles of cobalt were characterized by Transmission Electron Microscopy (TEM), Powder X-ray Diffraction (XRD), Thermal Gravimetric Analysis (TGA), QELS Data and Infrared Spectroscopy (IR). Crystalline size was 20 nm determined from the sharp peak at 2θ = 25 °C from the powder XRD. TEM images of cobalt nanoparticles without reducing agent having the diameter 20 nm with spherical shape and black color.

The Benzildiethylenetriamine was synthesized by the condensation method. It acts as a reducing agent. The synthesized Co nanoparticles were characterized by thermal, spectral and morphological studies.Figure optionsDownload as PowerPoint slideHighlights
