“…Similar conclusions were drawn in a study on the selective separation of ethylene/ethane, which confirmed that separation performance is related to stable monovalent silver ions [ 16 ]. Very recently, we employed Ag/ZSM-5(130) as an adsorbent for trace ethylene removal, which achieved a capacity of 4.89 mL·g ads −1 at room temperature, primarily thanks to the π-complexation of Ag + in the adsorbent [ 17 ].…”

Trace ethylene poses a significant challenge during the storage and transportation of agricultural products, causing over-ripening, reducing shelf life, and leading to food waste. Zeolite-supported silver adsorbents show promise for efficiently removing trace ethylene. Herein, hierarchical Ag/NZ5(X) adsorbents were prepared via different ammonia modifications, which featured enhanced ethylene adsorption ability. Ag/NZ5(2.5) exhibited the largest capacity and achieved near-complete removal at room temperature with prolonged efficacy. Characterization results indicated that the ammonia modification led to the formation of a hierarchical structure in the zeolite framework, reducing diffusion resistance and increasing the accessibility of the active sites. Additionally, desilication effects increased the defectiveness, generating a stronger metal–support interaction and resulting in a higher metal dispersion rate. These findings provide valuable insights into the development of efficient adsorbents for removing trace ethylene, thereby reducing food waste and extending the shelf life of agricultural products.
