DESCRIPTION:Prof. Matthew Kanan\, Stanford University\nThe longstanding re
 liance on fossil fuels as the principal energy source for society has boos
 ted the atmospheric CO2 concentration to a level that is unprecedented in 
 modern geological history. Since the use of carbon-containing fuels is ent
 renched in society\, controlling the atmospheric CO2 concentration may ult
 imately require recycling CO2 into liquid fuels and commodity chemicals us
 ing renewable energy inputs. Arguably the greatest challenge for this visi
 on is to develop efficient CO2 reduction catalysts. This talk will describ
 e our recent development of “oxide-derived” metal nanoparticles as ele
 ctroreduction catalysts. Oxide-derived metal nanoparticles are prepared by
  electrochemically reducing metal oxide precursors. This procedure results
  in highly strained metal nanocrystals. I will describe examples of these 
 catalysts that electrochemically reduce CO2 to CO with exceptional energet
 ic efficiency as well as a catalyst that selectively reduces CO to two-car
 bon oxygenates. The mechanisms of CO2 and CO reduction will be discussed b
 ased on electrokinetic measurements. Metal oxide reduction represents a 
 “top-down” approach to metal nanoparticle synthesis that can result in
  unique surface structures for catalysis.
