Surfactant-assisted synthesis of metallic cadmium, cadmium hydroxide nanostructures and their electrochemical charge storage properties

We report a simple, surfactant-assisted room temperature synthesis of metallic cadmium nanoparticle sheets and their subsequent hydrolysis to the formation of rice-shaped monoclinic cadmium hydroxide nanostructures. These new nanostructures have demonstrated 30–40 fold superior electrochemical charge storage capacity along with quantized double layer charging of metal nanoparticles as compared to the bulk cadmium.
