Infrared spectroscopic study of CO adsorption and electro-oxidation on carbon-supported Pt nanoparticles: Interparticle versus intraparticle heterogeneity

Article Abstract:

Fourier transform infrared (FTIR) spectroscopy and stripping voltammetry at saturation and submolecular CO coverages were used to investigate the influence of size on the CO adsorption and electrooxidation on Pt nanoparticles. Evidence is provided regarding strong intermolecular vibrational coupling of CO adsorbed on the low and high coordinated sites of Pt nanoparticles.

V at the rate of [Au12.sup.-]: An improved novel catalyst for CO oxidation?

Article Abstract:

The catalytic properties toward CO combustion of an encapsulated cluster V at the rate of [Au12.sup.-] were explored by means of plane-wave pseudopotential density-functional theory calculations. The cluster binds 12 CO molecules and cluster acts as catalyst since it enhances CO combustion under favorable conditions.
