Abstract ：
Trace ammonia reversible adsorption and sieving using solid adsorbents present a critical challenge in the practical deployment of ammonia-hydrogen fuel cells. Herein, we design porous polydivinylbenzene (P-PDVB) through one-pot solvothermal polymerization without additional templates. Subsequently, solvent-induced network swelling was performed to achieve deep sulfonation of the P-PDVB using chlorosulfonic acid, resulting in P-PDVB-SO3H-x, which possess large specific surface areas, abundant micro-mesoporosity, and high acid site densities. Notably, P-PDVB-SO3H-x demonstrate superior performance for the selective capture and sieving of NH3 from an N2/H2/NH3 mixture, outperforming most previously reported NH3 adsorbents. Thus, P-PDVB-SO3H-x can serve as an efficient adsorbent for the selective removal of trace ammonia from ammonia-hydrogen fuel cell systems, significantly improving both the efficiency and longevity of the fuel cells. This work highlights the potential of P-PDVB-SO3H-x as a promising candidate for enhancing ammonia-hydrogen fuel cell performance, paving the way for further exploration of advanced adsorbent materials in energy applications.

Abstract ：
Capture of acid gases holds crucial importance for addressing air pollution and climate change, where achieving a molar ratio for adsorption and separation of acid gases on an active site higher than 1.0 remains challenging. Herein, we demonstrate that three nitrogen-bonded one Zn sites within a single-crystalline-like porous carbon (Zn-N3@SC-PC) derived from controlled carbonization of ZIF-8-C equivalent to N with KCl, exhibit supra-multi-molar adsorption for CO2, COS, and H2S, even to 1:6 ratio for SO2 on the Zn-N3. This exceptional performance is attributed to the protruded structure in the Zn-N3@SC-PC for more coordination between Zn vacant orbital and acid gases evidenced by DFT calculation and in situ EXAFS. The high capacity for capturing acid gases on this adsorbent is crucial for future in carbon neutrality and environment protection.

Abstract ：
Translation and rotation are the two most fundamental forms of diffusion, yet their coupling mechanism is not clear, especially under confinement. Here, we provided evidence of the coupling between rotation and translation using a substituted benzene molecule as an example. A counterintuitive behavior was observed where the movement of the smaller molecule with an asymmetric shape was unexpectedly slower than the larger one with a symmetric shape in confined channels of zeolite. We showed that this diffusion behavior was caused by the presence of the specific and selective interaction of the asymmetric guest with the pores, which increased the local restricted residence time, thus inhibiting the translation under confinement, as further confirmed by dynamic breakthrough curves, uptake measurements, quasi-elastic neutron scattering, and 2H solid-state NMR techniques. Our work correlated asymmetric rotation and diffusion under a confined environment, which enriched our understanding of the coupling between rotation and translation and could shed light on a fundamental understanding of the diffusion process.

Abstract ：
The functionalities of N-doped carbons primarily rely on the exposed edge-nitrogen sites, which play a critical role in SO2 and CO2 adsorption. Rationally creating edge-nitrogen sites so as to promote their applications in various areas has not yet been well resolved. Herein, we developed ZnCl2-coordination-pyrolysis to design large specific surface area (1220 similar to 1645 m(2)/g) and edge-nitrogen rich porous carbons (E-NPC-x), where chitosan was employed as the carbon precursor. Similar to animals revealing new skin after shedding their old one, the migration and evaporation of zinc during pyrolysis leave abundant micro-mesoporosity, adjacent to which high proportion of edge-nitrogen sites was created due to strong coordination interaction between Zn2+ and nitrogen atoms. This feature significantly enhances the performance of E-NPC-x for acid gases capture, showing high SO2 capacities with fast adsorption equilibrium rates (14.6 mmol/g, 25 degrees C, 1.0 bar), and improved SO2/N-2 (0.1/0.9) IAST selectivities (251.1). The room-temperature diluted CO2 (2.0 vol%) under flue gas conditions, can be efficiently and precisely separated over the E-NPC-x with high breakthrough capacities (0.49 mmol/g). The nitrogen efficiencies of E-NPC-x for acid gases capture surpass those of current literature-reported N-doped porous carbons, underscoring its potential as a highly effective solution for mitigating environmental pollution. This work highlights a significant advance in the design of functional materials for environmental protection, addressing pressing challenges in acid gas management and contributing to a cleaner and more sustainable future.

Abstract ：
A novel sp2 carbon-conjugated covalent organic framework (COF), PZ-TFPT-COF, was designed for efficient sulfur dioxide (SO2) capture, addressing the critical issue of SO2 pollution, primarily emitted from the combustion of sulfur-rich fuels. The PZ-TFPT-COF demonstrates a remarkable SO2 adsorption capacity of 9.6 mmol/g at 25 °C and 1.0 bar, with a superior SO2/CO2 (0.1/0.9) Ideal Adsorbed Solution Theory (IAST) selectivity of 36.3. Structural characterizations through powder X-ray diffraction (PXRD), N2 adsorption–desorption isotherms, scanning electron microscopy (SEM), and high-resolution transmission electron microscopy (HRTEM) confirm its excellent crystallinity, uniform bulk morphology, and abundant, uniform nanoporosity. Additionally, PZ-TFPT-COF retains 96.9 % of its initial capacity after 8 adsorption–desorption cycles, highlighting its excellent recyclability. The binding energy between SO2 and the pyrazine nitrogen sites was calculated to be −40.29 kJ/mol, indicating their strong acid-base interactions. These results demonstrate that PZ-TFPT-COF is a promising candidate for advanced flue gas desulfurization, offering significant potential for cleaner industrial processes and improved air quality. © 2025 Elsevier B.V.

Abstract ：
Selective adsorption of sulfur dioxide (SO2) is an important clean technology for purification of exhaust gas from fossil fuel combustion. The widely applied zeolite-based adsorbents interact with SO2 through weakly physical adsorption, resulting in low adsorption capacity and selectivity for SO2. Herein, a facile strategy that combines improving the textural property of zeolite and optimizing adsorption sites is developed for efficient and stable SO2 adsorption. The micro-mesoporous silica sphere (MS) with high specific surface area and well-defined pore structure is obtained through a micelle expander assisted soft-template method, which can facilitate the dispersion and exposure of designed adsorption sites- methylated polyethyleneimine (mPEI). Since the Lewis basic sites of N in mPEI can strongly interact with the pi-receptor SO2, and the tertiary amine groups exhibit a weak attraction for CO2, the optimized MS supported mPEI adsorbent exhibits remarkable SO2 adsorption performance (7.5 mmol/g), exceptionally high SO2/N2 selectivity (16673) and SO2/CO2 selectivity (551). Moreover, it presents an outstanding stability in the adsorption-regeneration test. This work sheds light on the design of high-performance organic-solid composite adsorbent for selective capture of SO2.

Abstract ：
The amine -based materials pose high potential for the adsorption of sulfur dioxide (SO 2 ). This work is aimed at modulating the morphologies of SBA -15 adsorbents by controlling the precursor self -assembly processes, for the sake of optimizing the utilization efficiency of amine species in the polytertiary amine (PTA)-functionalized SBA15. It results that worm -like SBA -15 (WLS) material shows a better particle aspect ratio and well-defined pore structure, which helps to optimize the adsorption sites invoked by the preferable dispersion and exposure of PTA, thus amplifying the chemisorption of SO 2 on the adsorbent. Consequently, the functionalized WLS-PTA adsorbent exhibits remarkable SO 2 adsorption performance (15.43 mmol/g), exceptionally high selectivities of SO 2 /N 2 (27522) and SO 2 /CO 2 (652). Surprisingly, the desulfurization capacity can be further enhanced by the positive effect of the water vapor co -fed. It is unveiled that the whole SO 2 adsorption process mainly follows the dual site Langmuir-Freundlich isotherm model and Bangham model. This work sheds light on the design of polymer -solid composite adsorbents for selective capture of SO 2 .

Abstract ：
The introduction of enlarged and interconnected nanochannels into metal-organic frameworks (MOFs) overcome their micropore size restriction, enhances mass transportation, and improves the accessibility of anchored metal clusters. Herein, foamed Ce-MOF single crystals (F-Ce-MOF-SC-x) designed from a multiscale co-assembly is reported in the presence of a copolymer template and 1,3,5-trimethylbenzene as a structural regulator. The resultant F-Ce-MOF-SC-x possessed well-defined microporous tandem-ordered meso-macroporous foams with superior connectivity and versatile Ce-defective unsaturated sites (Ce-DUS). F-Ce-MOF-SC-x is applied as a stable carrier for anchoring polytertiary amines (PA) via coordination interactions with Ce-DUS. Owing to the superior ability of PA to recognize SO2, the resultant F-Ce-MOF-SC-x@yPA delivers exceptional performance in terms of the high-temperature reversible adsorption and separation of SO2, including a remarkable capacity for SO2, spectacular selectivity for SO2/CO2/N-2, an ultrafast adsorption equilibrium rate, and stability for 50 cycles. These characteristics are outstanding among those of MOFs and superior to those of many reported SO2 adsorbents.

Abstract ：
Herein, a variety of 2,6-diaminopyridine (DAP) derived nitrogen-doped hierarchically porous carbon (DAP-NHPC-T) prepared from carbonization-induced structure transformation of DAP-Zn-SiO2-P123 nanocomposites are reported, which are facilely prepared from solvent-free co-assembly of block copolymer templates P123 with pyridine-rich monomer of DAP, Zn(NO3)(2) and tetramethoxysilane. In the pyrolysis process, P123 and SiO2 templates promote the formation of mesoporous and supermicroporous structures in the DAP-NHPC-T, while high-temperature volatilization of Zn contributed to generation of micropores. The DAP-NHPC-T possess large BET surface areas (approximate to 956-1126 m(2) g(-1)), hierarchical porosity with micro-supermicro-mesoporous feature and high nitrogen contents (approximate to 10.44-5.99 at%) with tunable density of pyridine-based nitrogen sites (approximate to 5.99-3.32 at%), exhibiting good accessibility and reinforced interaction with SO2. Consequently, the DAP-NHPC-T show high SO2 capacity (14.7 mmol g(-1), 25 degrees C and 1.0 bar) and SO2/CO2/N-2 IAST selectivities, extraordinary dynamic breakthrough separation efficiency and cycling stability, far beyond any other reported nitrogen-doped metal-free carbon. As verified by in situ spectroscopy and theoretical calculations, the pyridine-based nitrogen sites of the DAP-NHPC-T boost SO2 adsorption via the unique charge transfer, the adsorption mechanism and reaction model have been finally clarified.

Abstract ：
The efficient deoxygenation of renewable biolipids into liquid alkanes within the diesel range is a key protocol for producing high-quality biofuels. In this work, the conversion of methyl palmitate and raw palm oil were accomplished utilizing a bifunctional catalyst of Ni catalysts supported on B2O3-ZrO2 under solvent-free conditions. Among various Ni loading ratios investigated, the catalyst featuring a 10 % Ni loading achieved 100 % conversion of methyl palmitate and 84.4 % of liquid yield, with approximately 65 % being C15 alkanes. Additionally, more than 91 % of hydrocarbons were also generated from raw palm oil. These results can be attributed to the synergistic interplay between the acid sites, following B2O3 modification, and the presence of Ni species. Furthermore, the analysis of product distribution, gas product detection and the kinetics calculation strongly supports that the deoxygenation process of methyl palmitate primarily follows the hydrodecarbonylation route, leading to the predominant formation of C15 alkane.
