In this research the synthesis of [Co(Salen)(PPh3)(H2O)]4[Fe(CN)6] and [Co(Salophen)(PPh3)(H2O)]4[Fe(CN)6] schiff base complexes was reported. Co3O4/CoFe2O4 magnetic nanoparticles were prepared by calcination of these complexes at 500, 550 and 600°C. Precursor complexes were identified by FT-IR and UV-Vis spectroscopy and their thermal behavior was studied via TG/DTA. Nanomagnetic samples were ...
The development of sustainable, ecofriendly, and cost-effective methods for the synthesis nanomaterials is an important aspect nanotechnology these days. present study was aimed at synthesizing cobalt oxide (Co3O4) nanoparticles by using plant extracts Aerva javanica, bacterial isolates from rhizospheric soil Potentilla atrosanguinea, Swertia petiolata, Senecio chrysanthemoides, fungus Fusarium...
Metal oxide nanoparticles are of practical interest in a variety of applications including high-density information storage [1], magnetic resonance imaging [2] and targeted drug delivery [3]. Many of these applications require particles of predetermined size and narrow size distribution. Processes that lead to particles with these characteristics are therefore of considerable interest. Cobalt f...
A novel one-step hydrothermal and calcination strategy was developed to synthesize the unique 1D oriented Co3O4 crystal nanofibers with (220) facets on the carbon matrix derived from the natural, abundant and low cost wool fibers acting as both carbon precursor and template reagent. The resultant W2@Co3O4 nanocomposite exhibited very high specific capacity and favorable high-rate capability whe...
