Abstract
A pseudo-first-order catalytic mechanism in
which both reactant and product of a redox reaction are
strongly immobilized on an electrode surface is theoretically
analysed under conditions of square-wave
(SWV) and staircase cyclic voltammetry (SCV). A
mathematical procedure is developed under diffusionless
conditions. The relationships between the properties of
the voltammetric response and both the kinetic parameters
of the redox reaction and the parameters of the
excitation signal are studied. The phenomenon of the
quasi-reversible maximum is discussed. A comparative
study between SWV and SCV is presented and the
limitations and advantages of both techniques, from
analytical and kinetic points of view, are discussed. The
theoretical predictions are experimentally confirmed by
the redox reaction of azobenzene in the presence of
hydrogen peroxide as an oxidizing agent.
