Though analyzing the effect of dispersion interactions in catalysis has been an objective of many past theoretical studies, the studies so far have been majorly limited to reactions predominantly involving weak physisorption. As a result, the effect of different methods has not been much explored for industrially important electrocatalytic reactions like ORR, OER, HER, and so on, which mainly involve the chemisorption of intermediates. However, since these reactions are characterized by the electrode-electrolyte media where solvents continuously interact with the intermediates, the overall energetics and activity of such reactions can significantly contribute to dispersion interactions. Water, the essential solvent mediating ORR, has been shown to have high sensitivity towards the dispersion correction method in determining the interaction with surfaces. Michaelides and co-workers have reported that non-local vdw-DF functionals improve the water-binding on metal surfaces considerably compared to a non-van der Waals GGA framework. Since the structure and the interaction of water molecules on the surface can be decisive in determining the energetics of reaction occurring on the surface, such reactions can also be expected to be associated with a sensitivity towards the method of dispersion correction. Furthermore, the studies conducted in this perspective were limited to focus on structural and adsorption-related properties without exploring the detailed mechanism of ORR. Moreover, several studies have also attempted to study ORR without considering the effect of dispersion interactions. Therefore, a study scrutinizing the role of dispersion interactions and the compatibility of different available DFT methods in predicting solvent-mediated detailed mechanisms of ORR activity deserves immense attention.
