Abstract
A composite includes a nonwoven carbon nanotube mat and an electroactive species disposed on the nonwoven carbon nanotube mat, wherein the electroactive species is capable of bonding with a target gas when the electroactive species is in a reduced state and releasing the target gas when the electroactive species is in an oxidized state. Electrode assemblies, electro-chemical cells, and gas separation systems including the composite are also described herein.
Claims24
A composite consisting of:
- a nonwoven carbon nanotube mat consisting of
- a plurality of entangled carbon nanotubes, each carbon nanotube of the plurality of entangled carbon nanotubes having an average diameter of 50 nanometers or less, and an average length of 50 micrometers to 2 millimeters;
- optionally, graphene, reduced graphene oxide, carbon black, Ketjen black, or structured carbon black;
- optionally, a polymer binder;
- and
- an electroactive species disposed on the nonwoven carbon nanotube mat, wherein the electroactive species is capable of bonding with a target gas when the electroactive species is in a reduced state and releasing the target gas when the electroactive species is in an oxidized state.
