Synthesis and Characterization of Cadmium Oxide NPs using Sapindus mukorossi (Soapnut) as natural surfactant

The synthesis of cadmium oxide nanoparticles has been carried out in the presence of Sapindus mukorossi (Soapnut) as a surfactant and the characterisation of the synthesized nanoparticles has been carried out using analytical techniques such as XRD, magnetic studies and SEM. The synthesised cadmium oxide was CdO. The structure of the CdO was face-centred cubic. Magnetic susceptibility measurements showed that there were no unpaired electrons in CdO. Hence, CdO is diamagnetic in nature. The exact size of the cadmium oxide was found using SEM. The size of the oxide was from 28 nm to 50 nm.
