SUMMARY:Catalytic Activation of Renewable Resources to make Polymers and F
 uels - Prof. Charlotte Williams (University of Oxford)

DESCRIPTION:This lecture will provide an overview of research in the Willi
 ams group into new catalyst development both for synthesis of polymers and
  for fuels\, such as methanol.[1]  The lecture will describe the preparati
 on and development of homogeneous catalysts for the polymerization of carb
 on dioxide and epoxides.[2]  In particular\, it will emphasise the importa
 nce of polymerization kinetics and structure-activity studies in developin
 g the chain shuttling mechanistic hypothesis.  This mechanism has been use
 d to guide the preparation of mixed metal\, heterodinuclear\, catalysts wh
 ich show synergic relationships and some high activities and selectivity v
 alues.[3]  The lecture will highlight the development and industrial appli
 cation of polycarbonates and polyols prepared from carbon dioxide. In the 
 second part\, research into new nanoparticle catalysts comprising ZnO and 
 Cu for the hydrogenation of carbon dioxide to methanol will be described.[
 4]  It will describe the potential to exploit organometallic reagents and 
 intermediates to prepare ultra-small colloidal nanoparticles\, as well as 
 new well-defined metal-hydroxyl clusters and 2-D layered materials. \n
