Abstract

See full text

A sorbent that is particularly effective for the efficient adsorption and subsequent desorption of ammonia is produced from a high-purity carbon material which is exposed to an oxidizing environment so as to produce an effective amount of at least one oxygen species on its exposed surfaces. The high purity carbon material may be produced by carbonizing a polymer material, and the sorbent may comprise a support having an open-cell, three dimensional, lattice-like structure.
