Synthesis and Characterization of MnO2 and CdO Nanoparticles
Synthesis of cost-effective colloidal Manganese dioxide and Cadmium oxide nanoparticles has been carried out quantitatively with monodispersity and controlled particle properties via soft chemical approach. The characterization of as synthesized nanoparticles was carried out with the help of FT-IR, UV-visible, TGA/DSC, XRD, SEM-EDX, TEM and BET. The optical band gap is used in order to determine a relationship between energy band gaps in the nanomaterials with respects to bulk. The particle size increases with calcination which leads to improved properties having a refined crystallinity after the removal of surface impurities. It is concluded that the particle properties can be controlled with the help of temperature, the amount of alkali used, reaction aging and the nature of solvents used.
