Bottom Line: The transformation over the last decade of the level of modelling and simulation of experiments has realised major advances such that electrochemical techniques can be fully developed and applied to real chemical problems of distinct complexity.This review focuses on the topic areas of: multistep electrochemical processes, voltammetry in ionic liquids, the development and interpretation of theories of electron transfer (Butler-Volmer and Marcus-Hush), advances in voltammetric pulse techniques, stochastic random walk models of diffusion, the influence of migration under conditions of low support, voltammetry at rough and porous electrodes, and nanoparticle electrochemistry.The review of the latter field encompasses both the study of nanoparticle-modified electrodes, including stripping voltammetry and the new technique of 'nano-impacts'.

ABSTRACT
Recent progress in the theory and practice of voltammetry is surveyed and evaluated.

Mentions: Numerical simulation145 has been explored to identify the effective standard electrochemical rate constant for both rough and porous surfaces using surface morphologies such as those shown in Figure 22 and 23. The former models a dense, but less than monolayer array of nanoparticles whilst the latter approximates a porous surface. In the former case, the apparent electrochemical rate constant (inferred from the peak potential of the voltammetry) was seen to vary according to75
