DESCRIPTION:Prof. Marc T.M. Koper\, Leiden Institute of Chemistry\, Leiden
  University\nAbstract: The electrocatalytic reduction of carbon dioxide is
  a promising approach for storing (excess) renewable electricity as chemic
 al energy in fuels. Here\, I will discuss recent advances and challenges i
 n the understanding of electrochemical CO2 reduction. I will summarize exi
 sting models for the initial activation of CO2 on the electrocatalyst and 
 their importance for understanding selectivity. Carbon–carbon bond forma
 tion is also a key mechanistic step in CO2 electroreduction to high-densit
 y and high-value fuels. I will show that both the initial CO2 activation a
 nd C–C bond formation are influenced by an intricate interplay between s
 urface structure (both on the nano- and on the mesoscale)\, electrolyte ef
 fects (pH\, buffer strength\, ion effects) and mass transport conditions. 
 This complex interplay is currently still far from being completely unders
 tood.\n\nReferences \nY.Y.Birdja\, E.Perez-Gallent\, M.C.Figueiredo\, A.J.

 \nBiography: Marc Koper is Professor of Surface Chemistry and Catalysis at
  Leiden University\, The Netherlands. He received his PhD degree (1994) fr
 om Utrecht University (The Netherlands) with a thesis on nonlinear dynamic
 s and oscillations in electrochemistry. He was an EU Marie Curie postdocto
 ral fellow at the University of Ulm (Germany) and a Fellow of Royal Nether
 lands Academy of Arts and Sciences (KNAW) at Eindhoven University of Techn
 ology\, before moving to Leiden University in 2005. His research in Leiden
  focuses on fundamental aspects of electrocatalysis\, theoretical and comp
 utational electrochemistry\, and electrochemical surface science\, in rela
 tion to renewable energy and chemistry. He has received various national a
 nd international awards\, among which the Spinoza Prize of the Netherlands
  Organization for Scientific Research (2021)\, Allen J. Bard for Electroch
 emical Science of The Electrochemical Society (2020)\, the Netherlands Cat
 alysis and Chemistry Award (2019)\, and the Faraday Medal (2017) from the 
 Royal Society of Chemistry. He is current President of the International S
 ociety of Electrochemistry.
