Formaldehyde yields from methanol electrochemical oxidation on platinum

Article Abstract:

The scientific and commercial implications of methanol fuel cells have sparked interest in methanol electrochemical oxidation. Thus, a study was conducted on formaldehyde formed from methanol electrochemical oxidation through sensitive fluorescence assay of methanol samples on platinum. The presence of formaldehyde was measured in 6 minute electrolysis periods. The findings demonstrate that the formaldehyde accounted for 30% of the total electrolysis charge at 0.2 and 0.4 volts. The data provided insights on methanol electrochemistry and oxidation pathways.

Catalytic methanol decomposition pathways on a platinum electrode

Article Abstract:

It has been possible to refer temporal advancements involved in methanol decomposition to the extent of CO poisoning. It is concluded that the methanol decomposition reaction that arises at short times does not lead to an effective surface CO formation process.

Sum frequency generation of CO on (111) and polycrystalline platinum electrode surfaces: evidence for SFG invisible surface CO

Article Abstract:

Results obtained using sum frequency generation show that carbon monoxide adsorbed on the platinum surface occupies both 3-fold and top-site positions on Pt(111) and only top site on polycrystalline platinum electrodes.
