TL;DR: It is concluded that there is a negligible difference in the surface electronic properties of these Pt/CB catalysts due to size variations and therefore, the ORR activities are not affected by the differences in the particle size.

TL;DR: The results of both 77Se EC-NMR as well as the XPS measurements indicate that Se, a semiconductor in elemental form, becomes metallic when interacting with Ru in catalysts made both by direct Se deposition onto Ru and from Ru3(CO)12.

TL;DR: In this article, the results of electrochemical nuclear magnetic resonance (EC NMR) and electrochemical measurements of CO chemisorbed onto these Pt/Pd catalysts were reported.

TL;DR: In this paper, a method of immobilization of catalytic metal/alloy nanoparticles on a gold disk for transfer from an electrochemical cell to UHV (without sample exposure to air) for XPS analyses was reported.

TL;DR: The first direct measurement of CO diffusion on nanoparticle Pt electrocatalysts at the solid/liquid interface is reported, carried out using 13C nuclear magnetic resonance (NMR) with a spin-labeling pulse sequence, opening up a new approach to the study of surface diffusion of adsorbed molecules on nanoparticles electrode catalysts.
