SUMMARY:Conférence de chimie :«Design and Development of Functional Porou
 s Materials»
DESCRIPTION:Cette conférence sera prononcée par le professeur Hirotom
 o Nishihara de la Tohoku University.
\nHôte : Professeur Garry Hanan
\nR
 ésumé: In this talk\, the author will introduce advanced porous or relat
 ed functional materials for the applications related to energy storage and
  conversion1. The first material is cellulose-based macroporous honeycomb 
 monoliths resembling natural tree xylem2. The honeycomb monoliths can be p
 repared by the ice-templating approach3\, and possess straight channels wi
 th a size range of 10-100 μm. Ultra-low pressure-drop and chemical flexib
 ility of the channel walls make the monoliths fascinating for separation a
 nd catalyst applications. The second material is mesoporous carbon with si
 ngle-graphene walls4. Among so many graphene-based materials recently prop
 osed\, this new material has distinct features such as a high surface area
  approaching the theoretical maximum\, ultra-high durability at high elect
 rical potential\, and mechanical elasticity. A great potential for applica
 tions to supercapacitors and fuel cells will be mentioned. The third mater
 ial is ordered carbonaceous frameworks (OCFs) inheriting structural and ch
 emical features of parent organic crystals5. The synthesis pathway for OCF
 s enables the development of new electrocatalysts having the advantages of
  molecular-based structure control and electric conductivity as well as ch
 emical/thermal stability.
