Three-Dimensional Air-Adsorbing Structure

A three-dimensional air-adsorbing structure that has a volume, comprising:

• (i) a three-dimensional, unitary, skeletal, porous scaffold having scaffold openings distributed within its volume, where the scaffold openings make up at least about 90% of the volume of the scaffold;
• (ii) air-adsorbing material particles;
• and
• (iii) one or more hydrophobic binders that couple air-adsorbing material particles to each other to form agglomerates and couples particles and agglomerates to the scaffold;
• wherein the structure has structure openings in the agglomerates and structure openings between agglomerates, such structure openings being open to the outside environment;
• wherein the structure further comprises closed volumes that are not open to the outside environment, and wherein the surface area of the structure openings plus the surface area of closed volumes, as measured by CT scanning with a resolution of at least 5 microns, is at least about 3 mm2/mm3 of air-adsorbing structure.
