Abstract
Highly uniform, stable nanobimetallic dispersions are prepared in a single step in the form of sols, gels, and monoliths, using organically modified silicates as the matrix and the stabilizer. The Pt−Pd bimetallic dispersions are characterized by UV−vis, TEM, SEM, and XRD measurements. The evolution of silicate was followed by IR spectroscopy. XPS and CO adsorption studies reveal that the structure of the particles consists of a palladium core and a platinum shell. Electrocatalysis of ascorbic acid oxidation has been demonstrated using thin films of silicate containing the nanobimetal particles on a glassy carbon electrode.
