The location of metal ion, Ag2+, Ca2+, Cu2+ and Y3+ in the SSZ-13 has been investigated with xenon adsorption measurement and 129Xe NMR spectrum. It was referred that the location of the metal ion varies depending on the corresponding charge. The ion-exchanged Ag ion was located in the alpha-cage to interact directly with xenon. Others multivalent cation contributed little with xenon because these were present near the six membered rings where xenon cannot access.
