Abstract Desulfurization technology is rather difficult and urgently needed for carbon dioxide (CO 2 ) utilization in industry. A new Cu(I)‐based adsorbent was synthesized examined the capacity of removing carbonyl sulfide (COS) from a CO stream an effort to solve competitive adsorption between COS seek opportunity advance capacity. wide range characterization techniques were used investigate physicochemical properties Cu(I) featuring π ‐complexation their correlations with performance. Meanwhile, first principal calculation software CP2K develop understanding mechanism, which can offer useful guidance regeneration. The adsorbent, prepared by using copper citrate citric acid on ZSM‐5 (SiO /Al O 3 = 25) carrier, outperformed other adsorbents varying formulations carriers capacities. Through optimization preparation conditions various adsorbents, breakthrough ( Q b further enhanced 2.19 mg/g 15.36 mg/g. formed stable ‐complex bonds Cu(I), as confirmed density functional theory calculations, verified significant improvement after regeneration at 600°C. above advantages render novel promising candidate cost‐effectiveness, high efficacy good regenerability desulfurization stream.

Abstract Hydrogen sulfide (H 2 S), a sulfur‐based toxic gas similar to the well‐known Mustard gas, has an unpleasant odor often causes uncomfortableness, destress, allergy, and/or mental failure during social occasions. Here, unique cotton fabric with its surface intensively coated (up 40 wt.%) zeolitic imidazolate framework‐8 (ZIF‐8) is synthesized via facile and low‐cost hydrothermal method. The results of H S capture test after 3 h exposure show that ZIF‐8@Cotton‐6 can achieve up 20 wt.% adsorption efficiency S, along 11.74 mmol × (g ZIF‐8) −1 coated, respectively. Unlike conventional absorption methods using porous carbon, ZIF‐8@Cotton composite provides safe, close‐distance skin contact long‐term protection absorb odor. Moreover, be easily integrated into existing textile engineering processes. hybrid fiber exhibits great potential on wearable garments protective textiles applications.
