Analysis of the applicability of short time chronoamperometry for the kinetic study of the hydrogen oxidation reaction
This work analyses the applicability of the chronoamperometric method for the evaluation of the kinetic parameters of the hydrogen oxidation reaction. It consists in the application of an overpotential step and the subsequent ...
Statistics and kinetics of single-molecule electron transfer dynamics in complex environments: A simulation model study
(American Institute of Physics (AIP), 2008-12-14)
Dynamics of the environments of complex systems such as biomolecules, polar solvents, and glass plays an important role in controlling electron transfer reactions. The kinetics is determined by the nature of a complex ...
Criteria for the selection of the scan rate in the evaluation of the kinetic parameters of the hydrogen oxidation reaction by a potentiodynamic sweep
(Elsevier Science Sa, 2015-07)
The use of the current density values obtained from a voltammetric sweep at a slow scan rate jvs(η) in place of those of a steady state polarization jss(η) for the determination of the kinetic parameters of the hydrogen ...
Interpretation of the experimental data on the reduction reaction of NO by CO on rhodium by Monte Carlo simulations and by solving the kinetic equations of the reaction mechanism
(AMER CHEMICAL SOC, 2006-04-20)
Some mechanisms of the reduction reaction of NO by CO on rhodium are analyzed and discussed, solving the kinetics equations and using Monte Carlo simulations, in terms of its ability to interpret the recent experiments of ...
