Complex interfaces are the key to new functional materials in energy conversion, energy storage, and energy-related catalysis: The fascinating functionalities of new materials arise from the physical and chemical properties of their interfaces. Key to their functionality is the transport of either electrons, ions, atoms, or molecules via nanostructured phase boundaries, often in a complex reaction environment.
Can we understand the chemistry and physics of such interfaces at the molecular level? Model strategies which can provide such insights are illustrated through examples from our current research. Three examples are presented from the fields of electrocatalysis and heterogeneous catalysis: (i) the development if model systems for proton exchange membrane fuel cell electrocatalysts with enhanced stability and noble metal efficiency, (ii) the development of model catalysts for hydrogen release from liquid organic hydrogen carriers, and (iii) the design of ionic liquid/solid interfaces with tailor-made catalytic properties. In all cases, complex yet atomically-defined model systems are developed under ultrahigh vacuum conditions. Using these models, we explore their chemical functionality under ideal surface science conditions and, subsequently, transfer this knowledge to realistic reactive environments, i.e. to high pressure, to the solid/liquid interface, and to electrochemically controlled conditions.
