Supplement to the theory of normal pulse voltammetry and its application to the kinetic study of methanol oxidation on a polycrystalline platinum electrode

Article Abstract:

The theory of normal pulse voltammetry for complex multistep multielectron transfer processes on a plane electrode was advanced and applied to the completely irreversible process of methanol oxidation to formic acid in the potential range from 0.3 to 0.8 versus Ag/AgCl. The results confirmed that this process is a very slow, completely irreversible kinetic process, as k(sub 0) is in the order of 10(super -9) cm/s for the rate-determining step.

Mechanisms of methanol decomposition on platinum: A combined experimental and ab initio approach

Article Abstract:

A combination of chronoamperometry, fast scan cyclic voltammetry, and theoretical methods are used to study and experiment the dual path mechanism for methanol decomposition on well-defined low Miller index platinum single crystal planes. The result shows that these methods can be utilized to help clarify fundamental aspects of reaction chemistry at a molecular level.

Adsorption of bisulfate and sulfate anions on a Pt(111) electrode

Article Abstract:

Bisulfate and sulfate anion adsorption on a platinum (Pt) (111) electrode from aqueous HClO4/H2SO4 media is studied using a modified radioactive labeling method. Results indicate that the species coadsorbed with sulfate are predominantly water molecules rather than hydronium cations.
