Effect of catalytic activity on the metallic nanoparticle size distribution: electron-transfer reaction between Fe(CN)6 and thiosulfate ions catalyzed by PVP-platinum nanoparticles

Article Abstract:

Studies done on the stability and catalytic activity of the PVP-Pt nanoparticle during its catalytic function for the electron-transfer reaction between hexacyanoferrate(III) ions and thiosulfate ions is presented. Studies reveal that the hexacyanoferrate(III) ions alone dissolve the Pt from the nanoparticle surface to form a cyano complex, as expected from thermodynamic considerations whereas thiosulfate seems to bind to the nanoparticle surface.

Raman studies on the interaction of the reactants with the platinum nanoparticle surface during the nanocatalyzed electron transfer reaction

Article Abstract:

Raman spectroscopy is used to understand the specific interactions of the individual reactants associated with the electron transfer reaction with the platinum nanoparticle surface. The results would help determine the mode of binding of thiosulfate ions onto the nanoparticle surface as well as provide more details about how the hexacyanoferrate-(III) ions interact with platinum nanoparticle surface.
