Abstract
High purity Cadmium (Cd) metal was used as raw material and placed in a microwave susceptor. an evaporation/oxidation process occurs under exposure to microwave in less than 2 minutes. Then, Evaporated cadmium reacted with oxygen and cadmium oxide was collected on the inner surface of a glassy container that was placed a few centimeters above the susceptor. Morphological and structural information of As-synthesized CdO nanopowder, were investigated via SEM and X-ray diffraction (XRD) spectroscopy. The antibacterial activities of different concentration of the CdO nanoparticles were tested by treating Escherichia coli (Gram negative) cultures with CdO nanoparticles. The Study indicates that cadmium oxide nanoparticles show effective antibacterial activity toward the gram-negative bacterium E. coli. Electrochemical properties of as-synthesized powder were investigated via linear and two vertex cyclic voltammetery in the presence of ethanol, a pair of Oxidation/reduction peaks were achieved.
