Molecular Sieve Encapsulated Single Walled Carbon Nanotubes

摘要

Molecular sieves comprise a family of nanoporous metal oxides that possess well defined pore architectures.The encapsulation of single walled carbon nanotubes (SWNT) within the pores has the potential of generating isolated very small diameter nanotubes that present interesting possibilities for phonon engineering and superconductivity.We have explored 2 methods of preparing SWNTs within the pores of molecular sieve materials.The first involves the thermal decomposition of organometallic templates inside various zeolite hosts.For example,The extralarge pore zeolite,UTD-1 (below)is prepared using the organometallic complex bis(penta-methycyclopentadienyl)cobalt(III) ion.
