Abstract
Carbon nanotube structures are disclosed in which nanotubes are disposed over a porous support such as a foam, felt, mesh, or membrane. Techniques of making these structures are also disclosed. In some of these techniques, a support is pretreated with a templated surfactant composition to assist with the formation of a nanotube layer.

A porous carbon nanotube containing structure comprising:
- a large pore support having through porosity;
- and
- carbon nanotubes disposed over the large pore support.
A method of adsorbing a chemical component, comprising:
- contacting a carbon nanotube-containing structure with a chemical component whereby the chemical component is adsorbed on the surface of the structure;
- wherein the carbon nanotube-containing structure comprises a support, carbon nanotubes disposed over the support, and a mesoporous silica layer disposed between the support and the carbon nanotubes.
A method of separating a chemical component, comprising:
- contacting a carbon nanotube-containing structure with a mixture whereby the structure separates at least one component from the mixture;
- wherein the carbon nanotube-containing structure comprises a support, carbon nanotubes disposed over the support, and a mesoporous silica layer disposed between the support and the carbon nanotubes.
