Synthesis of single wall carbon nanotubes from a lamellar type aluminophosphate (AlPO_4-L)

摘要

Single wall carbon nanotubes are synthesized from a lamellar type aluminophosphate, AlPO_4-L. The lamellar aluminophosphate was synthesized from hexamethyleneimine template. The latter was calcined at argon atmosphere for 12 h at 600 deg C. The resulting carbonaceous material was treated with 1 N H_2SO_4 to remove the aluminophosphate skeleton. Characterization of the resulting carbon revealed to contain single walled nanotubes. These nanotubes are applicable to store more hydrogen.
