Strategies for the Fabrication of Porous Platinum Electrodes
TL;DR: This article discusses techniques available for platinum electrode fabrication and describes methods to decorate porous metals other than platinum with a surface layer of platinum so that fabrication methods not performable with platinum can be applied to the fabrication of platinum electrodes with the special benefit of low platinum consumption.

Methane oxidation mechanism on Pt(111): A cluster model DFT study
TL;DR: Frequency analysis and transition-state theory were employed to show that the methane chemisorption elementary step is rate-limiting in the above mechanism, in agreement with published experimental electrochemical studies of methane oxidation on platinum catalysts that have shown the absence of an organic adlayer at electrode potentials that allow the oxidation of adsorbed CO.

Optimization of platinum dispersion in Pt-PEM electrodes: application to the electrooxidation of ethanol
TL;DR: In this article, the Pt-PEM electrodes were characterized by TEM, atomic absorption analysis, cyclic voltammetry and their polarization curves for ethanol electrooxidation and the platinization procedure was modified to enhance the roughness factor and thus to improve the electrocatalytic activity towards ethanol electrooxide.
