Pt-CeO2/C anode catalyst for direct methanol fuel cells
TL;DR: In this paper, a series of Pt-CeO 2 /C catalysts with various compositions of ceria were synthesized by wet impregnation method and the physicochemical characterizations of the catalysts were carried out by using Brunauer Emmett Teller (BET) surface area and pore size distribution (PSD) measurements, X-ray diffraction (XRD), XPS and transmission electron microscopy (TEM) techniques.

Catalytic oxidation and flow detection of carbohydrates at ruthenium dioxide modified electrodes.
Joseph Wang,Ziad Taha +1 more
TL;DR: Electrocatalytic oxidation is described also for related polyhydroxyl compounds (aldonic and aldaric acids and aalditols) and the effects of pH, flow rate, operating potential, surface "loading", concentration, and other variables are explored.

A polynuclear mixed-valent ruthenium oxide/cyanoruthenate composite that yields thin coatings on a glassy carbon electrode with high catalytic activity toward methanol oxidation
TL;DR: In this article, a polynuclear ruthenium oxide/cyanoruthenate films on carbon substrates were grown by cycling the potential between 0.5 and 1.0 V (vs SCE) for 5-90 min in fresh 2 m M RuCl 3 ·3 H 2 O, 2m M K 4 Ru(CN) 6 ·3H 2 O and 0. 5 M KCl solution at pH 2.

Surface Chemistry of Oxides
TL;DR: The chemistry of the surface of oxides depends to a large extent on the quantity and type of both physically and chemically (OH groups) absorbed water as discussed by the authors, and infrared spectroscopy coupled with a variety of chemical exchange processes has provided useful information on the nature and stability of the adsorbed species, and on the interaction of surface hydroxyl groups with adsorbates at the solid/vapour and solid/liquid interfaces.
