The Atomic Structural Dynamics of γ-Al2O3 Supported Ir−Pt Nanocluster Catalysts Prepared from a Bimetallic Molecular Precursor: A Study Using Aberration-Corrected Electron Microscopy and X-ray Absorption Spectroscopy

This study describes a prototypical, bimetallic heterogeneous catalyst: compositionally well-defined Ir−Pt nanoclusters with sizes in the range of 1−2 nm supported on γ-Al2O3. Deposition of the molecular bimetallic cluster [Ir3Pt3(μ-CO)3(CO)3(η-C5Me5)3] on γ-Al2O3, and its subsequent reduction with...
