Digital Simulation in Electrochemistry


Book Description

This book is the result of frustration. When I first became interested in digi tal simulation in 1967 (I didn't know the name then), there were no texts to tell one the how of it. This has not changed greatly since then; it is significant that just about all publications about the technique refer to a chapter by Feldberg in an electrochemical series, written in 1969. When I ran a course on the method recently, it became evident that this chapter is not enough for the raw beginner. Neither does he/she get much help from the mathematical textbooks which, at best, leave the special electrochemical aspects (if not a lot else) to one's imagination. This book, then, is written for practical digital simulators who do not have a friend who will tell them how to do it. The beauty of the digital approach is that one can separate out various dynamic processes taking place simultaneously. I have structured the book in this way. The major computing usually lies in the diffusion of substance, while the major program ming effort (and preparatory paper work) goes into the boundary conditions. These are treated separately.

Atomic-Scale Modelling of Electrochemical Systems


Book Description

Atomic-Scale Modelling of Electrochemical Systems A comprehensive overview of atomistic computational electrochemistry, discussing methods, implementation, and state-of-the-art applications in the field The first book to review state-of-the-art computational and theoretical methods for modelling, understanding, and predicting the properties of electrochemical interfaces. This book presents a detailed description of the current methods, their background, limitations, and use for addressing the electrochemical interface and reactions. It also highlights several applications in electrocatalysis and electrochemistry. Atomic-Scale Modelling of Electrochemical Systems discusses different ways of including the electrode potential in the computational setup and fixed potential calculations within the framework of grand canonical density functional theory. It examines classical and quantum mechanical models for the solid-liquid interface and formation of an electrochemical double-layer using molecular dynamics and/or continuum descriptions. A thermodynamic description of the interface and reactions taking place at the interface as a function of the electrode potential is provided, as are novel ways to describe rates of heterogeneous electron transfer, proton-coupled electron transfer, and other electrocatalytic reactions. The book also covers multiscale modelling, where atomic level information is used for predicting experimental observables to enable direct comparison with experiments, to rationalize experimental results, and to predict the following electrochemical performance. Uniquely explains how to understand, predict, and optimize the properties and reactivity of electrochemical interfaces starting from the atomic scale Uses an engaging “tutorial style” presentation, highlighting a solid physicochemical background, computational implementation, and applications for different methods, including merits and limitations Bridges the gap between experimental electrochemistry and computational atomistic modelling Written by a team of experts within the field of computational electrochemistry and the wider computational condensed matter community, this book serves as an introduction to the subject for readers entering the field of atom-level electrochemical modeling, while also serving as an invaluable reference for advanced practitioners already working in the field.

Electrocatalysis


Book Description

Catalysts speed up a chemical reaction or allow for reactions to take place that would not otherwise occur. The chemical nature of a catalyst and its structure are crucial for interactions with reaction intermediates. An electrocatalyst is used in an electrochemical reaction, for example in a fuel cell to produce electricity. In this case, reaction rates are also dependent on the electrode potential and the structure of the electrical double-layer. This work provides a valuable overview of this rapidly developing field by focusing on the aspects that drive the research of today and tomorrow. Key topics are discussed by leading experts, making this book a must-have for many scientists of the field with backgrounds in different disciplines, including chemistry, physics, biochemistry, engineering as well as surface and materials science. This book is volume XIV in the series "Advances in Electrochemical Sciences and Engineering".

Book Description

This is the first textbook in the field of electrochemistry that will teach experimental electrochemists how to carry out simulation of electrode processes. Processes at both macro- and micro-electrodes are examined and the simulation of both diffusion-only and diffusion-convection processes are addressed. The simulation of processes with coupled homogeneous kinetics and at microelectrode arrays are further discussed. Over the course of the book the reader's understanding is developed to the point where they will be able to undertake and solve research-level problems. The book leads the reader through from a basic understanding of the principles underlying electrochemical simulation to the development of computer programs which describe the complex processes found in voltammetry.This is the third book in the “Understanding Voltammetry” series, published with Imperial College Press and written by the Compton group. Other books in the series include “Understanding Voltammetry”, written by Richard G Compton with Craig Banks and also “Understanding Voltammetry: Problems and Solutions” (2012) written by Richard G Compton with Christopher Batchelor-McAuley and Edmund Dickinson.
