Kinetic Theory for Electrodic Phase Transitions: The Voltammogram
Abstract
In previous work we have purposed the sticky site model (SSM) for the chemisorption of adsorbates from fluids onto crystal surfaces. The crystal surface is represented by an array of sticky point adsorption sites. This permits the formal decoupling of the statistical mechanics into the 1- dimensional problem of the smooth electrode near an electrolyte, (the classic double layer problem), and the 2-dimensional lattice gas of the adsorption onto the array of sticky sites. In this model the binding process of individual atom is coupled to the cooperative effects that take place at the surface through mean field parameters, and the adsorption process is treated by studying the two dimensional lattice gas of the adsorbates, with two parameters obtained from the double layer problem. In the present work we extend the equilibrium (zero scanning rate) theory to include the dynamic regime of non-zero scanning rates.
