“…In addition, HCCP‐6 and HCCP‐11 also showed considerable working capacities of CH 4 storage with values of 445 and 375 mg g −1 at 5–80 bar and 298 K, respectively. Specially, the working capacity of HCCP‐6 was similar with MOF‐210 (431 mg g −1 ), KPOP‐1 (406 mg g −1 ) and Al‐soc‐MOF‐1 (425 mg g −1 ) and much higher than COF‐102 (320 mg g −1 ) and PAF‐1 (357 mg g −1 ) . On the other hand, taking mild synthetic condition and stability into consideration, HCCPs with commercial availability were promising materials for on‐board methane storage.…”

Construction of porous organic polymers (POPs) with high surface areas,well-defined nanopores,and excellent stability remains extremely challenging because of the unmanageable reaction process.Until now, only afew reported POPs have Brunauer-Emmett-Teller (BET) surface areas (S BET) exceeding 3000 m 2 g À1 .H erein, we demonstrate am olecular expansion strategy to integrate high surface areas,l arge nanopore sizes,a nd outstanding stability into POPs.Aseries of hyper-crosslinked conjugated polymers (HCCPs)w ith exceptional porosity are synthesized through this strategy. Specially, HCCP-6 and HCCP-11 exhibit the highest surface areas (S BET > 3000 m 2 g À1)and excellent total pore volumes (up to 3.98 cm 3 g À1)among these HCCPs.They present decent total CH 4 storage capacities of 491 and 421 mg g À1 at 80 bar and 298 K, respectively.Meanwhile,they are highly stable in harsh environments.T he facile and general molecular expansion strategy would lead to improved synthetic routes of POPs for desired functions.

“…In order to evaluate the capacity of MXenes as CO 2 sorbent under high pressure, we compared MXenes with other sorbents. Zeolite 13X has the capacity of 7.38 mmol/g [44] and porous polymers have the capacity of 11.9 mmol/g [45]. The first reported capacity of Ti 3 C 2 T x MXene (5.79 mmol/g) is close to the capacity of those common sorbents.…”

Two-dimensional carbide MXenes (Ti 3 C 2 T x and V 2 CT x ) were prepared by exfoliating MAX phases (Ti 3 AlC 2 and V 2 AlC) powders in the solution of sodium fluoride (NaF) and hydrochloric acid (HCl). The specific surface area (SSA) of as-prepared Ti 3 C 2 T x was 21 m 2 /g, and that of V 2 CT x was 9 m 2 /g. After intercalation with dimethylsulfoxide, the SSA of Ti 3 C 2 T x was increased to 66 m 2 /g; that of V 2 CT x was increased to 19 m 2 /g. Their adsorption properties on carbon dioxide (CO 2 ) were investigated under 0-4 MPa at room temperature (298 K). Intercalated Ti 3 C 2 T x had the adsorption capacity of 5.79 mmol/g, which is close to the capacity of many common sorbents. The theoretical capacity of Ti 3 C 2 T x with the SSA of 496 m 2 /g was up to 44.2 mmol/g. Additionally, due to high pack density, MXenes had very high volume-uptake capacity. The capacity of intercalated Ti 3 C 2 T x measured in this paper was 502 V·v -1 . This value is already higher than volume capacity of most known sorbents. These results suggest that MXenes have some advantage features to be researched as novel CO 2 capture materials. suitable material to adsorb and capture CO 2 .In general, pressure and/or temperature swing approaches are used to capture CO 2 in porous materials. The porous materials, as CO 2 sorbents, should have superior properties in terms of capacity, stability, kinetics, selectivity, and regeneration [1]. Up to now, a wide range of sorbents for CO 2 capture, have been used and studied, including metal organic frameworks (MOFs) [2], functionalized porous silica [3], activated carbon [4], zeolites [5], metal oxides, and microporous polymers [6]. Among these sorbents, MOFs exhibit very high CO 2 uptake up to 54.4 mmol/g under high pressures (5 MPa) at 298 K [2]. Despite the excellent adsorption capacities, MOFs are much more expensive 238

< 2 nm), such as zeolites, metal-organic frameworks (MOFs), covalent organic frameworks (COFs), and porous aromatic frameworks (PAFs), combine high specific surface areas, large pore volumes and shape-selectivity effects, which makes them key materials for a wide range of applications, including catalysis, gas separation/purification, ion exchange, gas storage, and sensing. The diverse framework compositions and functionalities of microporous materials represent a huge challenge for their structural characterization as well as evaluation of their performances. Analytic tools such as X-ray diffraction (XRD), electron microscopy and adsorption-desorption isotherms are now routinely employed for characterization of microporous materials in order to establish the structure-property relationships, and hence, to facilitate the rational design of advanced materials with improved property. However, the structure determination of porous materials using single crystal XRD requires high crystallinity and long-range ordering of the framework. Solid-state NMR (SSNMR) has emerged as a powerful spectroscopic technique with atomic-level resolution, complementary to XRD, in the investigation of structures in Microporous materials have attracted a rapid growth of research interest in materials science and the multidisciplinary area because of their wide applications in catalysis, separation, ion exchange, gas storage, drug release, and sensing. A fundamental understanding of their diverse structures and properties is crucial for rational design of high-performance materials and technological applications in industry. Solid-state NMR (SSNMR), capable of providing atomic-level information on both structure and dynamics, is a powerful tool in the scientific exploration of solid materials. Here, advanced SSNMR instruments and methods for characterization of microporous materials are briefly described. The recent progress of the application of SSNMR for the investigation of microporous materials including zeolites, metal-organic frameworks, covalent organic frameworks, porous aromatic frameworks, and layered materials is discussed with representative work. The versatile SSNMR techniques provide detailed information on the local structure, dynamics, and chemical processes in the confined space of porous materials. The challenges and prospects in SSNMR study of microporous and related materials are discussed.
