Large-Inner Thin-walled Carbon Nanotubes, 30-60nm, >60%

Large-diameter, thin-walled, multi-walled carbon nanotubes (CNTs) are prepared by catalytic cracking of acetylene using a nickel-based catalyst. They typically have an inner diameter greater than 20 nm, a wall thickness of around 5 nm, and an outer diameter of 30-60 nm for most CNTs.
