Abstract CdCO3 nanostructures were synthesized via simple hydrothermal method by Cd(NO3)2, ethylenediamine and hydrazine as reagents. The products were characterized with X-ray diffraction scanning electron microscopy, energydispersive X-ray spectroscopy and Fourier transform infrared spectroscopy. Different parameter’s effect on product size and morphology were investigated. Keywords

Introduction In recent years, there has been great research interest in the synthesis of nanostructured CdXO3 (X = C, Si, Ge, Sn, Pb) materials because of their wide range of technological applications [1]. For instance, cadmium carbonate has been used as core material for fabrication of hollow polyelectrolyte capsules, solid phase reactor for indirect determination of cyanide, and precursor for the preparation of technologically important CdO nanostructured material [2–4]. Metal carbonates, especially calcium carbonate (CaCO3), have been extensively studied due to their abundance in nature and also their important industrial application in paints, M.

plastics, rubber, or paper [5]. However, the researches for transition metal carbonate nanomaterials, such as CdCO3, PbCO3 and MnCO3 are rarely reported. Recently, CdCO3 nanoparticles, nanowires, nanobelts and nanorolls were prepared via wet chemical methods [6, 7]. In presence work we synthesized CdCO3 nanostructures via simple hydrothermal approach. The product was characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX) and Fourier transform infrared spectroscopy (FT-IR). Several parameters such as Cd2?:en mole ratio, reaction temperature and time were investigated on product size and morphology.
Experimental Materials and Physical Measurements All the chemical’s reagents used in experiments such as Cd(NO3)2, ethylenediamine (C2H8N2) and hydrazine (N2H4.H2O) were of analytical grade and used as received without further purification. XRD patterns were recorded by a Rigaku D-max C III, X-ray diffractometer using Ni-filtered Cu Ka radiation. SEM images were obtained on Philips XL-30ESEM equipped with an energy dispersive X-ray spectroscopy. FTIR spectra was recorded on a Shimadzu Varian 4300 spectrophotometer in KBr pellets.
