| 1. An adsorbent material, comprising:
a Ag-exchanged zeolite having: a Si/Al ratio of less than 10, less than or equal to about 2.0 weight percent moisture content,
a Ag content of between 80-110%, hydrothermal structural damage of no greater than 15%, and a ΔCO working capacity greater
than or equal to 0.045 mmol CO/g Ag-zeolite, the ΔCO working capacity determined from a reference breakthrough test.
