Preparation and Characterization of Three-Dimensional Pt Nanoparticle Networks

We have synthesized nanostructured metal/organic networks by cross-linking preformed aluminum-organic-stabilized Pt nanoparticles in solution with organic spacer molecules. The protonolytic cross-linking mechanism presented makes use of reactive aluminum methyl groups at the surface of the particles. The particles and their networks have been characterized by electron microscopy and IR spectroscopy. For the structural characterization of the hybrids, anomalous small-angle X-ray scattering (ASAXS) was applied.
