abstract

synthesis, identification and thermal behavior studies of nanoparticles cobalt (ii) bromide has been studied in this research. cobalt (ii) bromide was synthesized by planetary high-energy ball mill. the general formula of this compound is cobr2.6h2o. the synthesized nanoparticles were characterized by fourier transform infrared spectroscopy and also size and structure of synthesized nanoparticles were studied by analyzing x-ray diffraction and morphology of surface and structure of synthesized nanoparticles were studied by scanning electron microscopy. this compound has many applications in mineral synthesis as a catalyst. the nanoparticles of cobr2.6h2o synthesized with smaller size of 35 nm, and its sem images show that the morphology of particles surface is as like as layer. also, the thermal behavior of these nanoparticles is considered by using of dta /tga thermal analysis.

Synthesis and study of co-doped zinc oxide nanoparticles with copper, magnesium, calcium, and cobalt ions by microemulsion method

In the present study, zinc oxide nanoparticles were synthesized by simultaneous doping of Zn0.98Cu0.02O with Ca2+, Mg2+, and Co2+ ions using the microemulsion method. The phase, crystallization, and particle size of samples were identified by X-ray diffraction (XRD) analysis. The formation of the desired phase was confirmed by, X-ray diffraction. Also, the infrared spectrum (Far-FTIR) was confi...
