Advances in electrochemistry at solid-liquid interfaces are vital for driving technological innovations that are needed to deliver reliable, affordable, and environmentally-friendly energy. In the first part of presentation, we highlight the key achievements in the development of new materials for efficient hydrogen and oxygen production in electrolyzers and, in the reverse, their utilization in fuel cells. A key fundamental issue addressed in this presentation is the degree to which the fundamental understanding of the synergy between covalent and non covalent interactions can form the basis for any predictive ability in tailor making real world catalysts. Common descriptors such as the substrate-hydroxide binding energy and the hydroxide-oxide•••H–OH interactions in the double layer are found to control individual parts of the hydrogen and oxygen electrochemistry that govern the efficiency of water-based energy conversion and storage systems.
In many respects, understanding processes at atomic-/molecular levels in organic solvents is much less advanced than the corresponding electrochemistry in aqueous systems. This intrinsic gap in understanding, however, has a tendency to mask the inherently close ties that exist between processes in these two environments. As a consequence, in the second part of this presentation is to build a bridge between electrochemistry that controls individual parts of the water cycle and processes in a Li-O2 battery as well as Mg deposition on negative electrodes and Mg intercalation in oxide-host of positive electrode. We conclude that understanding the complexity (simplicity) of electrochemistry at atomic and molecular levels would open new avenues for design and deployment of alternative energy systems.
