► A novel nanostructure of CdO was synthesized by mechanochemical reaction followed by calcination. ► Mechanochemical method is a simple and low-cost to synthesize nanomaterials. ► The obtained precursor was characterized by FT-IR, NMR techniques and elemental analysis. ► SEM images showed cauliflower-like shape of sample with components average diameter of 68
nm. ► The rods and tubes bundles with single crystalline nature were revealed by ED pattern and TEM images.
Cauliflower-like cadmium oxide (CdO) nanostructure was synthesized by mechanochemical reaction followed calcination procedure. Cadmium acetate dihydrate and acetamide were used as reagents and the resulting precursor was calcinated at 450
°C for 2
h in air. The structures of the precursor and resultant product of the heating treatment were characterized using Fourier transform infrared (FT-IR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy and elemental analysis, X-ray powder diffraction (XRD), energy-dispersive X-ray spectroscopy analysis (EDX), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and electron diffraction pattern (ED). SEM and TEM images revealed the cauliflower-like morphology of the sample. This structure includes the bundles of rods and tubes in nanoscale, which combine with each other and form the resulting morphology with the average diameter, 68
nm of the components. ED pattern indicated the single crystal nature of the formed bundles.
