“…The CO 2 adsorption capacities and conditions of several wood- or cellulose-based sorbents are summarized in Table 1 . At ambient condition, the CO 2 adsorption capacity of TO-wood/Cu 3 (BTC) 2 in this work is superior to that of the wood- or cellulose-based CO 2 sorbents loaded with PEI, 59 acetylated CNCs, 60 and zeolite 61 and is comparable to that of the APTES-grafted TO-CNFs/silica aerogels. 34 Although the TO-CNFs/PEI foam showed a high CO 2 adsorption capacity of 2.22 mmol g –1 at 80% RH, contribution from water is negligible.…”

Mechanical stability and multicycle durability are essential for emerging solid sorbents to maintain an efficient CO 2 adsorption capacity and reduce cost. In this work, a strong foam-like composite is developed as a CO 2 sorbent by the in situ growth of thermally stable and microporous metal-organic frameworks (MOFs) in a mesoporous cellulose template derived from balsa wood, which is delignified by using sodium chlorite and further functionalized by 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-mediated oxidation. The surface carboxyl groups in the TEMPO-oxidized wood template (TO-wood) facilitate the coordination of the cellulose network with multivalent metal ions and thus enable the nucleation and in situ growth of MOFs including copper benzene-1,3,5-tricarboxylate [Cu 3 (BTC) 2 ], zinc 2-methylimidazolate, and aluminum benzene-1,3,5-tricarboxylate. The TO-wood/Cu 3 (BTC) 2 composite shows a high specific surface area of 471 m 2 g –1 and a high CO 2 adsorption capacity of 1.46 mmol g –1 at 25 °C and atmospheric pressure. It also demonstrates high durability during the temperature swing cyclic CO 2 adsorption/desorption test. In addition, the TO-wood/Cu 3 (BTC) 2 composite is lightweight but exceptionally strong with a specific elastic modulus of 3034 kN m kg –1 and a specific yield strength of 68 kN m kg –1 under the compression test. The strong and durable TO-wood/MOF composites can potentially be used as a solid sorbent for CO 2 capture, and their application can possibly be extended to environmental remediation, gas separation and purification, insulation, and catalysis.

Hierarchically structured zeolites can mitigate problems arising from the slow transport in the micropores, such as diffusion limitations. Hence, a manifold of different preparation methods for hierarchical zeolites have been developed over the years and the corresponding zeolites showed superior performance due to enhanced mass transport caused by higher diffusivities in the additional pore system and reduced diffusion path length in the micropores. The dimensions of the additional secondary “transport” pores in these materials is a major factor affecting their diffusion properties and consequently their catalytic performance. Interestingly almost all reports focus on the generation of additional mesopores and study of catalytic performance of mesoporous zeolites. Larger macropores with pore diameters of more than 50 nm, however, have some intrinsic advantages over mesopores that make them very attractive for catalytic applications. In the last years, methods for the preparation of zeolites and zeolite composites with additional macropores have been developed. These developments have brought about a novel and promising class of hierarchically structured materials; zeolites with macropores. This review gives an overview about different preparation routes for zeolites with inter or intra crystalline macropores as well as zeolite composites with macropores and summarizes the first studies regarding catalytic their performance.

“…Besides the above classified adsorbents, other materials were also tested as promising candidates for CO 2 separation, such as hydrotalcite‐like compounds, [174] ionic liquids, [175] and metal nanoparticles [176] . Due to the improved processability, [177] zeolite‐polymer hybrids also attracted increasingly interest in recent years [178,179] . For instance, 3D printing can be used to create the polymer/zeolite hybrid structure, which consists of polyamide‐imide (Torlon) as the penetrated network and zeolites 13X and 5 A as adsorption sites [180] .…”

Advances in Post‐Combustion CO₂Capture by Physical Adsorption: From Materials Innovation to Separation Practice

The atmospheric CO2 concentration continues a rapid increase to its current record high value of 416 ppm for the time being. It calls for advanced CO2 capture technologies. One of the attractive technologies is physical adsorption‐based separation, which shows easy regeneration and high cycle stability, and thus reduced energy penalties and cost. The extensive research on this topic is evidenced by the growing body of scientific and technical literature. The progress spans from the innovation of novel porous adsorbents to practical separation practices. Major CO2 capture materials include the most widely used industrially relevant porous carbons, zeolites, activated alumina, mesoporous silica, and the newly emerging metal‐organic frameworks (MOFs) and covalent‐organic framework (COFs). The key intrinsic properties such as pore structure, surface chemistry, preferable adsorption sites, and other structural features that would affect CO2 capture capacity, selectivity, and recyclability are first discussed. The industrial relevant variables such as particle size of adsorbents, the mechanical strength, adsorption heat management, and other technological advances are equally important, even more crucial when scaling up from bench and pilot‐scale to demonstration and commercial scale. Therefore, we aim to bring a full picture of the adsorption‐based CO2 separation technologies, from adsorbent design, intrinsic property evaluation to performance assessment not only under ideal equilibrium conditions but also in realistic pressure swing adsorption processes.
