Abstract: The nature and properties of surface-enhanced vibrational spectra of molecules adsorbed on surfaces that can enhance the absorption and the emission of electromagnetic radiation are discussed. Examples of surface-enhanced resonant Raman scattering, surface-enhanced Raman scattering in the near-infrared and surface-enhanced infrared are given. The rough surfaces used are metal island films coated with a nanometric organic film using the Langmuir-Blodgett technique or deposited by vacuum evaporation.

TL;DR: Pt/Ru (1:1), Pt/Ru/Ni (5:4:1) was shown to have a lower turnover number and a smaller activation energy for methanol oxidation as discussed by the authors.
Abstract: Pt/Ru (1:1), Pt/Ni (1:1), and Pt/Ru/Ni (5:4:1) electrocatalysts for use in direct methanol fuel cells (DMFCs) were synthesized by reduction with NaBH 4 combined with freeze-drying and their activity as a methanol oxidation catalyst was examined at different temperatures. The onset potential of Pt/Ru/Ni (5:4:1) was lower than that of Pt/Ru (1:1) and current density of Pt/Ru/Ni (5:4:1) was larger than that of Pt/Ru (1:1). In addition, Pt/Ru/Ni (5:4:1) had a larger turnover number and a smaller activation energy for methanol oxidation than Pt/Ru (1:1). Polarization and power density data in a liquid-feed DMFC unit cell test were in good agreement with the voltammetry and chronoamperometry data, for which Pt/Ru/Ni (5:4:1) showed a higher catalytic activity than Pt/Ru (1:1). The role of Ni from the standpoint of the oxidation states of Ni and the modification of the electronic structure of Pt by X-ray photoelectron spectroscopy is discussed.

TL;DR: In this paper, a comparative investigation was done on the interaction of glycerol using polyaniline supported Pt nanoparticles, Pt-Pd bimetallic nanoparticles and Ru nanoparticles fabricated on indium tin oxide (ITO) electrodes.
