Advances in electrocatalysis at solid-liquid interfaces are vital for driving technological innovations that are needed to deliver reliable, affordable, and environmentally-friendly energy. In this 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 that will be addressed 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. Links between aqueous- and organic-based environments will also be addressed, encouraging the “fuel cell” and “battery” communities to move forward together.
