We have successfully synthesized transition metal hydroxide ( Ni(OH)2, Co(OH)2 ) nanoplates and transition metal layered double hydroxide nanoplates in an aqueous solution. In addition, we could attach Pt nanoparticles on the hydroxide nanoplates accociated with enhancement for electrochemical catalytic acitivity because of combination transition metal hydroxide and Pt. We could control the ratio of transition metal hydroxide to Pt. We have also measured excellent electrochemical catalytic performance compared to the commercial materials. The synthesized nanomaterials were characterized by using TEM, XRD and XPS. The synthesized nanomaterials have a uniform size and shape. |
