TL;DR: The quantitative analysis of the different surface sites on platinum samples is attempted from pure voltammetric data, and it is shown that irreversibly-adsorbed bismuth and tellurium have been revealed to be sensitive to the presence of (111) terrace domains of different width whereas almost all sites involved in (100) ordered domains have been characterized through germanium adatoms.

TL;DR: The results pointed out that the surface structure of the electrodes plays an important role on the reactivity of both oxidation processes, and thus the electrocatalytic properties strongly depend on thesurface structure/shape of the nanoparticles, in particular on the presence of sites with (111) symmetry.

TL;DR: In this article, a voltammetric profile of preferentially shaped platinum nanoparticles has been used to analyze the different sites present on the surface of nanoparticles in NaOH solutions and revisited in sulfuric and perchloric acid media.

TL;DR: In this paper, the performance of ZnO and Cu 2 O/ZnO surfaces in a filter-press electrochemical cell for the continuous electroreduction of CO 2 into methanol was examined.

TL;DR: This work synthesizes and compares four types of Pt NPs: spherical, cubic, hexagonal, and tetrahedral-octahedral, and shows the hexagonal PtNPs displaying the highest activity for ORR in two acid electrolytes.
