Electrocatalytic materials and interfaces for the production of solar fuels and chemicals Peter Strasser Department of Chemistry, Technical University Berlin, Berlin, Germany, pstrasser@tu-berlin.de The rising share of renewable electricity is testament to the increasing importance of solar/wind-electric routes to harvest sun light in form of potential differences and flowing free electrons. While some electricity is used directly or stored capacitively, an increasing portion calls for direct conversion into valuable molecular solar fuels or chemicals. This conversion in the dark is made possible by heterogeneous electrocatalysis on the surface of solid electrodes. While deeper fundamental understanding of the origin of kinetic barriers is needed for the design of more efficient, tailor-made electrochemical interfaces for the production of fuels and chemicals, more understanding of the interplay of chemical kinetics and transport of solvent, ions, and reactants is critically needed to design robust devices. In this presentation, I will report on recent advances in our design and understanding of electrocatalytic materials, interfaces, mechanisms, and layered devices relevant to the conversion of electricity into value-added molecular compounds, using in-situ/operando X-ray spectroscopic, microscopic, scattering or spectrometric techniques. Examples include water splitting to green hydrogen and the conversion of CO 2 into chemicals.
