In this mini review, we present a highly abridged overview of some of the challenges faced when modeling charge transfer processes across the electric double layer with DFT. Focusing primarily on charge transfer kinetics, we highlight polarizable continuum models (PCMs) and their use in evaluating energetics in the adiabatic limit of electron transfer, i.e. treating electrons grand canonically during a coupled proton-electron transfer (CPET) reaction. We highlight their use in understanding electrocatalytic processes, in particular the ability to localize transition states at constant potential.

This approach offers built-in cross-validation, significantly enhancing the precision and accuracy of the sensors. These self-checked systems have unlocked the potential of nanomaterials with versatile properties, enabling their simultaneous use across various sensing mechanisms. Electrochemical sensors, in particular, have leveraged this approach, leading to the development of dual-mode electrochemical-based sensors that pair electrochemistry with techniques such as Colorimetry, Fluorescence, Photoelectrochemistry, or even two different Electrochemical methods.
