Easy access to platinum nanoclusters
14 December 2005
A simple and efficient way to make stabilised platinum nanoparticles has been designed for nanotechnological applications.
Giuliano Longoni and colleagues at the University of Bologna, Italy, have designed a new one-step synthesis for the [Pt38(CO)44]2- dianion from the metal hexachloride salt. These molecular metal carbonyl nanoclusters have had limited use in nanotechnology as until now their purification has been difficult.
Since this new method uses commercially available starting materials such as K2PtCl6, water and carbon monoxide, no special apparatus or skill is required. These advantages make it readily available for use in nanoscience by non-specialists.
Longoni hopes this new method will assist in the preparation and characterisation of new molecular platinum carbonyl clusters that have potential use in molecular electronics and nanolithography.
