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 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 “dark” e-conversion is made possible by heterogeneous electrocatalysis on the surface of solid electrodes coupled to mass and charge transport processes. Sustainable materials synthesis pathways coupled to novel advanced characterization techniques result in a deeper understanding of the origin of reaction kinetic barriers and the origin of transport limitations. This is critically needed for the design of more efficient, electrochemical materials, interfaces, and electrodes for practical electrolytic devices for the production of e-fuels and e-chemicals.
In this presentation, I will report on recent advances in our design and understanding of electrocatalytic materials, interfaces and electrodes relevant to the electrochemical conversion and valorization of CO2 into value-added molecular compounds. Focus will be placed on CO and ethylene as key target e-compounds in conventional liquid cells and Gas Diffusion Electrodes.
