Journal ArticleDOI
Electrocatalysis of methanol oxidation
TL;DR: Most relevant aspects of methanol electrooxidation on Pt electrodes, including voltametric as well as spectroscopic data on the system are presented and discussed Parallel reaction pathways have been demonstrated, producing CO 2 and HCOOH or HCHO as soluble products as mentioned in this paper.
Journal ArticleDOI
Methanol oxidation on PtRu electrodes. Influence of surface structure and Pt-Ru atom distribution
Teresa Iwasita,Teresa Iwasita,Harry E. Hoster,A. John-Anacker,Wen-Feng Lin,Wolf Vielstich,Wolf Vielstich +6 more
TL;DR: In this paper, the authors compared the catalytic activity of different types of PtRu catalysts for methanol oxidation and reported the dependence of the respective catalytic activities upon the surface composition.
Journal ArticleDOI
Parallel pathways of ethanol oxidation: The effect of ethanol concentration
TL;DR: In this paper, the effects of ethanol concentration on the yields of CO2, acetic acid and acetaldehyde as electrooxidation products were investigated, and it was shown that the main oxidation product at low ethanol concentrations is acetic acids, CO2 being produced to a minor extent.
Journal ArticleDOI
New mechanistic aspects of methanol oxidation
TL;DR: In this paper, the authors measured the yields of different products at 0.6 V using smooth polycrystalline and Pt(1.1) electrodes and found that strong adsorption of sulfate hinders methanol oxidation by inhibiting the dissociative steps where the adsorbed CO intermediate is formed.
Journal ArticleDOI
Catalysis of CO electrooxidation at Pt, Ru, and PtRu alloy. An in situ FTIR study
TL;DR: In this paper, a comparative study of CO electrooxidation on different catalysts using in situ FTIR spectroscopy is presented, where polycrystalline Pt and Ru and a PtRu (50:50) alloy are used.
