1. A lithium ion-exchanged zeolite particle comprising:
cages defined by 8-membered rings, 9-membered rings, 10-membered rings, 12-membered rings or a combination thereof, wherein Li3PO4 is present within the cages; and
Li+ and NH4+ cations; and
wherein the lithium ion-exchanged zeolite particle comprises (i) less than or equal to about 0.1 at % of one or more of Na+, K+, Mg2+, or Ca+; and (ii) NH4+ in an amount greater than an amount of the one or more of Na+, K+, Mg2+, or Ca+.
