SUMMARY:Conférence avec le ProfesseurRandy Thummel (Houston)
DESCRIPTION:Titre : A Systematic Approach to a Molecular Light-Diven Water 
 Splitting Catalyst.Cette conférence sera prononcée (en anglais) par le 
 Professeur Randy Thummel\, du département de chimie à la Houston Univers
 ity. Il sera de passage à Montréal dans le cadre d'une soutenance de th
 èse en chimie.Résumé : This lecture will discuss artificial photosynthe
 sis from the perspective of using the energy of sunlight to accomplish the
  chemistry involved in converting water into its elements. The development
  of dinuclear and eventually mono-nuclear ruthenium(II) complexes for the 
 electrochemical oxidation of water to dioxygen will be presented. Catalyst
  design will be discussed in the context of the actual bond breaking and b
 ond making steps required for water splitting. In addition to activation b
 y the strong chemical oxidant Ce(IV)\, similar catalysts will be activated
  photochemically through the excited state of appropriate Ru(II) photosens
 itizers. The development of homogeneous molecular systems incorporating bo
 th the oxidation catalyst and the photosensitizer also will be presented. 
 Finally a Co(II) polypyridine complex that catalyzes water reduction to fo
 rm hydrogen will be discussed.Information supplémentaire
