DESCRIPTION:Prof. Kyoung-Shin Choi\, Department of Chemistry\, University 
 of Wisconsin-Madison\, USA.\nOur research employs electrochemistry as the 
 primary synthetic tool to fabricate a variety of solid state materials as 
 thin-film type electrodes and catalysts. These materials are selected for 
 use in electrochemical and photoelectrochemical cells that produce fuels\,
  building block chemicals\, and clean water using renewable energy sources
 . We develop electrodeposition-based synthesis strategies to design and op
 timize electrode compositions and architectures to achieve desired electro
 chemical\, photoelectrochemical\, and catalytic properties. Our most estab
 lished core research area is the development of photoelectrochemical cells
  for solar water splitting. This project involves the synthesis and unders
 tanding of photoanodes\, photocathodes\, hydrogen evolution catalysts\, an
 d oxygen evolution catalysts. The optimization of the interface between ph
 otoelectrodes and catalysts is also a critical research area. In this pres
 entation\, we will discuss various strategies to improve photoelectrode pe
 rformances and photoelectrode/catalyst interfaces using a BiVO4 photoanode
  as an example. We will also present electrochemical and photoelectrochemi
 cal processes that we have been developing to make key building block chem
 icals via oxidative and reductive biomass conversion where water is used a
 s the oxygen or hydrogen source. Finally\, we will briefly introduce our n
 ew research direction where we develop electrochemical and photoelectroche
 mical processes to enable seawater desalination. By showcasing three diffe
 rent research areas\, all based on electrochemical and photoelectrochemica
 l processes\, this presentation will demonstrate the versatility and the e
 normous potential of electrochemical and photoelectrochemical applications
 .
