Issue Date: | 2010 | Publisher: | American Chemical Society | Citation: | Nano Letters 10(3): 964-973 (2010) | Abstract: | The introduction of metallic traces into the synthesis of platinum nanocrystals (Pt NCs) has been investigated as a surfactant-independent means of controlling shape. Various nanocrystal morphologies have been produced without modification of the reaction conditions, composition, and concentration other than the presence of cobalt traces (<5%). In the presence of metallic cobalt (a strong reducer for Pt cations) cubic Pt NCs are obtained, while cobalt ions or gold NCs have no effect on the synthesis, and as a result, polypods are obtained. Intermediate shapes such as cemented cubes or cuboctahedron NCs are also obtained under similar conditions. Thus, various NC shapes can be obtained with subtle changes, which illustrates the high susceptibility and mutability of the NC shape to modification of the reaction kinetics during the early reduction process. Our studies help progress toward a general mechanism for nanocrystal shape control. | Description: | 10 páginas, 10 figuras, 1 tabla, 1 esquema. | Publisher version (URL): | http://dx.doi.org/10.1021/nl100032c | URI: | http://hdl.handle.net/10261/48921 | DOI: | 10.1021/nl100032c | ISSN: | 1530-6984 | E-ISSN: | 1530-6992 |
