DESCRIPTION:Prof. Wilson A. SMITH\nDepartment of Chemical Engineering\,\nD
 elft University of Technology\, The Netherlands\nChE-605 - Highlights in E
 nergy Research seminar series\nElectrocatalytic CO2 reduction has the dua
 l-promise of neutralizing carbon emissions in the near future\, while prov
 iding a long-term pathway to create energy-dense chemicals and fuels from 
 atmospheric CO2. The field has advanced immensely in recent years\, taking
  significant strides towards commercial realization. While catalyst innova
 tions have played a pivotal role in increasing the product selectivity and
  activity of both C1 and C2 products\, slowing advancements indicate that 
 electrocatalytic performance may be approaching a hard cap. Meanwhile\, in
 novations at the systems level have resulted in the intensification of CO2
  reduction processes to industrially‑relevant current densities by usin
 g pressurized electrolytes\, gas-diffusion electrodes and membrane-electro
 de assemblies to provide ample CO2 to the catalyst. The immediate gains i
 n performance metrics offered by operating under excess CO2 conditions go
 es beyond a reduction of system losses and high current densities\, howeve
 r\, with even simple catalysts outperforming many of their H-cell counterp
 arts. This talk will focus on some of the underlying reasons for the obser
 ved changes in catalytic activity\, and propose that further advances can 
 be made by shifting additional efforts in catalyst discovery and fundament
 al studies to system-integrated testing platforms.  Recent results will b
 e shown that highlight the use of computational modeling\, in-situ/operand
 o spectroelectrochemistry\, and reactor engineering to understand and opti
 mize electrochemical systems across many scales.\n\nThe seminar can also b
 e followed remotely by joining the online Cisco WebEx meeting (connection 
 possible 15 minutes before the talk).\nSee here the documentation how to i
 nstall the Cisco WebEx add-on on your computer.\nIn case of problem\, you 
 can contact our IT support (37679 - it.vs@epfl.ch )\n
