Special Issue Information

Dear Colleagues,

The seriousness of the threat posed by the increase in carbon dioxide (CO2) emissions is significant and alarming in the present environment. Addressing the challenge of achieving carbon neutrality by closing the carbon cycle is a significant global endeavor. To achieve this objective, interdisciplinary research initiatives integrating cutting-edge materials and chemical processes are imperative for advancing carbon capture, storage, and utilization (CCUS) technologies. This Special Issue on nanomaterials will showcase the latest advances in CO2 capture and conversion technology to promote the transition to a sustainable society. We welcome high-quality submissions in the form of articles, reviews, or perspectives that push boundaries in the field of CCUS.

Selective adsorption is regarded as a promising alternative for propylene/propane separation. However, the similar physicochemical properties of these two components pose a challenge in developing adsorbents that simultaneously exhibit high selectivity and substantial adsorption capacity. This study aims to achieve molecular sieving of propylene and propane by precisely controlling the pore size of silicoaluminophosphate (SAPO) molecular sieve. The pore size of the eight-membered-ring SAPO-35 molecular sieve is tuned via ion exchange to fall between the kinetic diameters of propylene and propane, enabling selective adsorption of propylene while excluding propane molecules. Ion exchange treatment increased the equilibrium adsorption selectivity of the SAPO-35 from 2.2 to 11.4, placing it among the highest-performing molecular sieve-based adsorbents. This modification also substantially improved the material’s regeneration capability at ambient temperature. Theoretical calculations reveal that steric hindrance effects, arising when gas molecules diffuse through the eight-membered-ring channels, contribute significantly to the high adsorption selectivity. Breakthrough experiments demonstrated that Na-SAPO-35 achieves a dynamic selectivity of 15.9 for propylene/propane separation. The development of Na-SAPO-35 adsorbents with high selectivity, substantial adsorption capacity, and robust durability is critical for advancing the industrial implementation of adsorption-based separation technologies.
