Suggestions of Topics for Discussion at
Architectures Session

• Redox-coupled or -switchable catalysts
• New architectures that resist degradation from
  oxidizing or reducing agents
• Development of homogeneous catalysts that are
  stable at high temperature
• Ways to develop new supramolecular and
  nanovessel catalysts--how to move from binding
  studies to the development of useful materials
  understanding the principles that control
  catalysis in active sites of enzymes and large
  synthetic molecular systems
• Use of molecular switches and other nanoscale
  devices to control catalysts and turn them on and
  off how to combine developing sensor technology
  with catalyst technology
• Multicomponent and multifunctional catalysis how
  to design clusters that approach the catalytic
  reactivity of metal surfaces role of
  interstitial atoms in cluster chemistry
• Developing new catalysts by attaching homogeneous
  catalysts to supports developing better
  characterization methods for these systems
• Design of multidentate ligands to allow
  well-defined surface coordination and catalysis
• Novel catalyst supports (e.g., nanotubes,
  specially fabricated silicon)
• Developing novel methods for synthesizing
  nanostructured materials to produce catalysts and
  the reverse use of catalysts in the production
  of nanostructured materials
• Biomimetic catalysis - what can we learn from
  nature about designing synthetic catalysts that
  will do what nature can do, but we cannot (e.g.,
  C-H activation that mimics MMO or Cyt P450,
  methanogenesis)?
• Understanding and improving enantioselective
  surface-catalyzed reactions surfaces modified
  with chiral molecules, inherently chiral surface
  structures, molecular imprinting of surfaces with
  chiral reagents
• Understanding the similarities and differences
  between the mechanisms of operation of
  homogeneous and heterogeneous catalysts, and
  elucidating the source of the differences
  developing a common set of themes, concepts and
  language that will bridge the gap between workers
  in homogeneous and heterogeneous catalysis
• Facilities needed to enhance the development of
  targeted future research activities new
  spectroscopic techniques available or envisioned
• The role of nanoscience in improving our ability
  to control catalytic reactions and make molecular
  and atomic scale measurements on operating
  catalytic systems
