Silica-supported bimetallic Pt–Cu and Pt–Au catalysts were prepared using bimetallic molecular cluster precursors as the metal source. The molecular precursors were adsorbed onto the support from an organic solvent, dried under vacuum, calcined under flowing oxygen, and reduced with hydrogen. The resulting catalysts were characterized with CO chemisorption, diffuse reflectance Fourier transform spectroscopy...
