Claim Text:
1. A three-dimensional air-adsorbing structure that has a volume, comprising: (i) a three-dimensional, unitary, skeletal, porous 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 air-adsorbing material and the agglomerates are coupled to the scaffold by creating a water-based emulsion of air-adsorbing material, agglomerates of the material, and binder, and then impregnating the scaffold with this emulsion; wherein the emulsion is dried at least in part at a temperature below the freezing point of the emulsion.
