ICIQ Seminar

by Prof. Amanda C. Garcia, University of Amsterdam (The Netherlands)



In this talk, it will be discussed the solvent effect on CO2RR on nanostructured Cu electrode in acetonitrile solvent with different amounts of water. Similar to what has been observed for aqueous media, online gas chromatography showed that CO2RR in acetonitrile solvent is also structure dependent, since CuNC was the only surface (in comparison to polycrystalline Cu) capable of producing a significant amount of ethylene, provided there is enough water present in the electrolyte (>500 mM). In situ Fourier Transform Infrared (FTIR) spectroscopy showed that in acetonitrile solvent, the presence of CO2 strongly inhibits HER by driving away water from the interface .
