Methanol and CO electrooxidation
The methanol oxidation reaction has been the subject of a large number of studies in the past.[1, 2] Early work revealed a complex reaction mechanism,[3–6] indicating the electrocatalysis of methanol oxidation as the most difficult task in the realization of a direct methanol fuel cell (DMFC). Several metal catalysts were proposed for the reaction, most of them based on modifications of Pt with...
متن کامل{331}-Faceted trisoctahedral gold nanocrystals: synthesis, superior electrocatalytic performance and highly efficient SERS activity.
We investigate the effect of gold (Au) seeds prepared in cetyltrimethylammonium chloride solution (CTAC-Au seeds) on the index facets of trisoctahedral gold nanocrystals (TOH Au NCs). We demonstrate that monodisperse {331}-faceted TOH Au NCs with controllable sizes (from 60 to 255 nm) can be successfully prepared in high yield by using 3.0 nm CTAC-Au seeds or as-prepared 70 nm TOH Au NCs as see...
متن کاملMethanol Oxidation on Cu(110)
In this paper we highlight the important contribution made by Bob Madix to the understanding of catalysis at single crystal surfaces, focusing here on a favourite model system of his, namely the oxidation of methanol on Cu(110). Madix showed clearly that the methoxy was the pivotal intermediate involved, and it is bound to the surface through the oxygen atom. Here we demonstrate the nature of t...
متن کاملElectrooxidation of methanol on doped polypyrrole films in acidic media
Electrooxidation of methanol was realised on platinum and perchlorate anion doped polypyrrole film electrodes in acidic media. A systematic kinetic investigation was performed and optimum experimental conditions for the preparation of the electrocatalytic system were determined. The presence of ClO4 − anions was confirmed by XPS analysis of the doped polymer matrix. © 2001 Elsevier Science B.V....
متن کاملHierarchical Nanoporous Gold-Platinum with Heterogeneous Interfaces for Methanol Electrooxidation
The electrocatalysts utilized as the prospective electrodes in fuel cells and high efficient energy conversion devices require both the interconnected channels for efficient electrolyte transportation and the superior catalytic activity with long service life. In this work, nanoporous gold with the rigid skeletons in three dimensions is partially decorated by porous platinum shell containing na...
