METHOD FOR PRODUCING A NANOTUBULAR CARBON MATERIAL, AND THE MATERIAL PRODUCED THEREBY

摘要

Nanoporous nanotube-like carbon can be produced in large quantities, with excellent yield and purity and at a low cost by a novel method involving the halogenation of aluminium carbide at a temperature above 450 DEG C, preferably about 500 DEG to 800 DEG C, and most preferably at 550 DEG to 750 DEG C. The nanotubular material exhibits nanotubes with the following approximate dimensions: length between about 6 and 50 nm, typically 14 to 22 nm; inner diameter between 5.5 and 27 nm, typically 10 to 14 nm; outer diameter about 6 to 30 nm; and total wall thickness of about 0.7 to 5 nm, typically 1.6 to 3.4 nm.
