Structure sensitivity of methanol electrooxidation pathways on platinum: An on-line electrochemical mass spectrometry study

Article Abstract:

The selectivity and structure sensitivity of the methanol oxidation pathways on basal planes and stepped platinum single-crystal electrodes are investigated by monitoring the mass fractions of C[O.sub.2](m/z 44) and methylformate in 0.5 M [H.sub.2]S[O.sub.4] and 0.5 M HCl[O.sub.4] by using on-line electrochemical mass spectrometry (OLEMS). A detailed scheme of the methanol oxidation mechanism is presented based on the literature and the OLEMS data.

Electrooxidation of CO(sub ad) intermediated from methanol oxidation on polycrystalline Pt electrode

Article Abstract:

The poisonous intermediate of methanol oxidation on a Pt electrode is validated to be CO(sub ad) by an electrochemical method. The analysis of the effect of the approximate treatment on the kinetic parameters has indicated that the approximate treatment for the bimolecular elementary reactions is reasonable in a certain extent.

Methanol oxidation on a copper catalyst investigated using in situ X-ray photoelectron spectroscopy

Article Abstract:

An investigation on the surface and near-surface regions of an active catalyst and the adjacent gas-phase reactants is presented under reaction conditions using in situ X-ray photoelectron spectroscopy (XPS). The study concluded that the active catalyst surface is metallic copper that contains a subsurface oxygen species.
