Abstract
Disclosed herein is a nanostructured material comprising defective carbon nanotubes chosen from impregnated, functionalized, doped, charged, coated, and irradiated nanotubes, and combinations thereof. The defective carbon nanotubes contain a defect which is a lattice distortion in at least one carbon ring. Also disclosed is a method of purifying fluids, such as liquids, including water, as well as gases, including the air using, this nanostructured material.
Claims35
A material for reducing contaminants in a fluid, said material comprising:
- carbon nanotubes, and
- a porous support medium for said carbon nanotubes, said porous support medium being permeable to the flow of said fluid,
- wherein a plurality of said carbon nanotubes comprise:
- a lattice distortion,
- at least one functional group, and
- are fused or bonded to said porous support medium, to another carbon nanotube, or to a combination thereof.
