Synthesis, structural, morphological, functional, optical and particle size enhanced cadmium oxide nanoparticles on electro-chemical applications

Abstract

The co-precipitation technique of cadmium oxide (CdO) nanoparticles in aqueous solutions at high temperatures was employed in this investigation. The potential for electrochemical activity was studied. Thus, a powder X-ray diffractometer was used to quantitatively evaluate the Scherer-calculated crystallite grain size and dislocation density. Scanning electron microscopy imaging and analysis revealed the distinct shape and structure of CdO nanoparticles. The above-mentioned nanoparticles were sorted into their respective functional groups by FTIR spectroscopy. The CdO nanoparticle size was measured in the nanometre range using a dilution-based particle size analyzer. There was a significant improvement in the CdO nanoparticles' ability to absorb UV-visible light. Their unique colours of light were made visible in the spectrum of their fluorescence emission, which allowed them to be clearly authenticated. An electrochemical probe into the phenomenon of super capacitance has revealed its fundamental characteristics. This CdO nanomaterial might be useful for scientific investigation.
