Stability
1) Solution Stability: Maintains high Xe adsorption capacity at 42% relative humidity, stable structure when exposed to air for 2 days, but transforms to another phase in liquid water;
2) Thermal Stability: Good thermal stability, tolerant up to 500 K (approximately 227℃); thermal decomposition temperature of the dehydrated framework is about 575℃.

Preservation & Activation
1) Store in a dry and sealed container at room temperature;
2) Activation Method: After methanol exchange, activate under dynamic vacuum at 100℃ for 12 hours; or activate at a lower temperature to optimize Xe adsorption performance.

Applications
1) Off-gas separation in nuclear fuel reprocessing: Efficiently and selectively adsorbs Xe at room temperature, separates Xe/Kr with higher adsorption capacity than benchmark materials;
2) CO₂ capture and separation: Exhibits CO₂/N₂ selectivity over 45 under flue gas conditions, enabling reversible CO₂ adsorption;
3) Noble gas separation: Selectively separates Xe from simulated nuclear facility off-gas mixtures, resistant to humidity effects.
