Chapter 6: DFT Modelling Tools in CO₂ Conversion: Reaction Mechanism Screening and Analysis

The computer-aided molecular modelling of the catalytic conversion of carbon dioxide (CO₂) intogreen' fuels offers a comprehensive view of the chemical events taking place during the process. This provides crucial information aboutwhere',how', and 'why' and also allows the in silico hypothesising of those promising catalysts before the experimental testing of their catalytic performance. Among the variety of quantum mechanical approaches, well-resolved density functional theory (DFT) has been proven as a fast, robust, and powerful methodology for such purposes. In the present chapter, we review different fundamental aspects of the chemical reactivity with special emphasis on the theoretical point-of-view as well as fully treating the thermodynamics, kinetics, and additional aspects for the DFT modelling of the CO₂ conversion mechanism screening through the electrochemical approach.
