Shape-Controlled Synthesis of Colloidal Platinum Nanoparticles Temer S. Ahmadi, Zhong L. Wang, Travis C. Green, Arnim Henglein, Mostafa A. El-Sayed * The shapes and sizes of platinum nanoparticles were controlled by changes in the ratio of the concentration of the capping polymer material to the concentration of the platinum cations used in the reductive synthesis of colloidal particles in solution at room temperature. Tetrahedral, cubic, irregular-prismatic, icosahedral, and cubo-octahedral particle shapes were observed, whose distribution was dependent on the concentration ratio of the capping polymer material to the platinum cation. Controlling the shape of platinum nanoparticles is potentially important in the field of catalysis. |
