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 ：
A solid ionic liquid adsorbent, obtained by grafting [C3N][SO4H] onto porous carbon was reported. Characterizations including IR, XPS and TEM provided the structural information of the sulfonic acid groups on the porous carbon matrix, affirming the feasibility of this synthesis method. The results elucidated the synergy between the sulfonic acid groups and the pore structure of porous carbon, resulting in substantial enhancements in both ammonia adsorption capacity and adsorption selectivity. Moreover, this absorbent exhibited the ability to capture minute concentrations of ammonia below 0.1 ppm with great efficacy and excellent regeneration property within 8 cycles. This simple grafting and acid activation technique proffers a valuable tool for designing adsorbent of trace ammonia within ammonia-hydrogen fuel cells.

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 ：
gamma-ray radiation-induced grafting strategy was first employed to immobilize 4-aminobenzo-15-crown-5 onto a covalent organic framework (COF). This endeavor culminated in the successful synthesis of a class of two-dimensional crown ether-modified COFs (named [15C5]n%-(TzDa-G-x%)), marking the maiden utilization of COFs in the realm of 6Li/7Li isotope separation. These COFs exhibited swifter adsorption kinetics than alternative adsorbents. Among them, [15C5]57%-(TzDa-G-50%) with its excellent crystallinity, porosity, and stability exhibited the best performance in Li+ adsorption and 6Li/7Li isotope separation. The Li+ adsorption in acetonitrile achieved a capacity of 3.6 mg center dot g-1 within 30 min and a saturation capacity of 7.3 mg center dot g-1. The single -stage separation factor of 6Li/7Li isotopes was 1.014 +/- 0.001. The results of dynamic adsorption column experiments showed that the packed column made of [15C5]57%-(TzDa-G-50%) maintained stable performance during four cycles of Li+ adsorptionelution, with over 99% Li+ removal rate in acetonitrile. This crown ether-modified COF has potential application in 6Li/7Li isotope separation, and this radiation-assisted synthesis strategy is expected to become universal in the modification of COFs for diverse applications.

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. © 2024
