Cr(0) nanoparticles were synthesized by solution reduction process successfully. The influence of parameters on the size of Cr(0) nanoparticles was studied and the referential process parameters were obtained. The morphology and structure of the synthesized Cr(0) nanoparticles were characterized by Transmission Electron Microscopy (TEM), Powder X-ray Diffraction (XRD), Thermal Gravimetric Analysis (TGA), QELS Data and Infrared Spectroscopy (IR). The results show that Cr(0) nanoparticles are of high purity. XRD analysis revealed all relevant Bragg’s reflection for crystal structure of Cr metal. XRD spectrum also indicates that there is no oxidation of Cr(0) nanoparticles to chromium oxide. TEM showed nearly uniform distribution of particles in methanol which was confirmed by QELS. Cr(0) nanoparticles can be synthesized easily by reducing agent and are quite stable too.
Graphical abstractNanostructures of chromium were characterized with TEM and powder XRD techniques. A transmission electron microscope (TEM) studies nanoparticle of chromium defines the shape and size. Nanoparticles of Cr were synthesized by benzildiethylenetriamine (reducing agent) from chromium nitrate with stirring and refluxing in the various solvents (acetonitrile, ethanol, methanol, water, dimethylsulfoxide and cyclohexane). The TEM images of chromium nanoparticles were obtained with and without reducing agent having spherical shape (10–20 nm and 50 nm in diameter), black color The best result was obtained in the ethanol..Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Synthesis of novel reducing agent (benzildiethylenetriamine). ► Synthesis and characterization of Cr nanoparticles. ► Structural and morphological study of these nanoparticles. ► Thermal study of these nanoparticles. ► TEM images of these nanoparticles.
