Preparation and Characterization of Silane-Stabilized, Highly Uniform, Nanobimetallic Pt−Pd Particles in Solid and Liquid Matrixes

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