Abstract ：
Efficient removal of p-arsanilic acid (p-ASA) from contaminated water is crucial for mitigating arsenic contamination. In this study, a membrane adsorbent named CFM-Zn is developed by retanning Zn on a collagen fiber membrane (CFM). This development leverages the unique physicochemical properties of CFM and the strong affinity of Zn for p-ASA. The membrane is composed entirely of green, low-carbon, and recyclable materials, achieving sustainable removal of p-ASA and embodying the concept of using waste to treat waste for environmental recovery. Remarkably, it exhibits an ultra-high capacity of up to 515.46 mg & sdot;g-1. Additionally, CFM-Zn demonstrates moderate reusability, with effectiveness maintained for at least five cycles. This study could advance the development of bio-based materials for water pollutant removal, expand the applications of leather waste, and significantly promote environmental purification and resource recycling.

Abstract ：
Heavy metal contamination in water threatens human health and ecological security, necessitating efficient and sustainable remediation technologies. Adsorption is a widely used method due to its cost-effectiveness, high selectivity, and ease of operation. Among various adsorbents, conjugated microporous polymers (CMPs) have shown great potential for heavy metal removal, benefiting from their pi-conjugated structures, high surface area, tunable pore sizes, and strong metal ion interactions. However, challenges remain in synthesis and material properties. Extensive postsynthetic modifications may introduce structural complexity and compromise adsorption performance, while excessive functionalization can lead to pore blockage, reducing available adsorption sites. Additionally, inadequate distribution or low grafting density of chelating groups may weaken metal ion binding. Further challenges include enhancing selectivity, developing eco-friendly regeneration methods, improving stability in complex environments, and achieving large-scale production. Addressing these issues requires optimizing synthetic strategies, precisely incorporating functional groups, and improving pore structure control. This review summarizes recent advances in CMP-based heavy metal adsorption, discusses adsorption mechanisms and structural optimization, and identifies future research directions to advance their practical application in water purification.

Abstract ：
Extracting uranium from seawater has become an important method to supplement the nuclear industry. Herein, we introduce a simple route to load conjugated microporous polymers onto collagen fiber membranes, resulting in a novel membrane adsorbent material (CMPA-F/CFM) for uranium capture. Its Langmuir adsorption capacity reaches 304.9 mg·g−1 (at 318 K), with fast adsorption kinetic of 60 min, and excellent adsorption selectivity with Kd = 4.69 × 104 mL·g−1 under the temperature of 298 K, initial concentration of 50 mg·L-1, and pH = 7, thus allowing a satisfactory adsorption performance in a 7-day real ocean experiment with a uranium adsorption capacity of 1.25 mg·g−1. Furthermore, in continuous dynamic adsorption experiments, CMPA-F/CFM could treat up to 19.0 L·g−1 of low-enriched uranium (LEU) solution (1 mg·L-1), with a uranium removal rate of up to 87.5 % (10 L of seawater). This study demonstrates broad potential application of membrane adsorption in extraction of low-enriched uranium. © 2024 Elsevier Ltd

Abstract ：
The semiconductor industry's rapid evolution necessitates ultra-high-purity N-methyl pyrrolidone (NMP) as an essential electronic-grade solvent. The development of an efficient coordination material to reduce trace metal ions, particularly Na and K metal ions, to below 1 ppb in NMP solution is a significant challenge. To address this, a novel coordination material, St-DVB-g-ACE, has been developed for the removal of Na and K metal ions from NMP. The material was synthesized by grafting 4 '-aminobenzo-15-crown-5-ether onto a strong acid gel resin. The resulting St-DVB-g-ACE-3 exhibited excellent coordination performance for Na and K metal ions, with maximum Langmuir adsorption capacities reaching 20,000 mu g/g and 33,333 mu g/g, respectively. Of particular interest was the ability of St-DVB-g-ACE-3 to reduce all trace metal ions in industrial-grade NMP to below 1 ppb within a fixed bed column, achieving the stringent requirements for electronic-grade NMP at the G3 level. Additionally, the absorbent enhances the purity of NMP from 99.82 % to 99.84 %, indicating that the material is not dissolved and can exist stably in NMP. Its excellent recyclability and reproducibility make it highly practical for industrial use. Density functional theory (DFT) simulation, complemented by spectral analyses, revealed the interaction force and thermodynamic properties between Na and K metal ions and crown ether ring, and illustrated the interaction between anionic sulfonic group (- SO3- ) and metal ions. The prepared resin-grafted crown ether adsorbents are highly effective in the thorough removal of trace metal ions from NMP solution, offering a novel and effective method for the production of electronic-grade NMP.

Abstract ：
Dimethyl carbonate (DMC) is a crucial chemical raw material widely used in organic synthesis, lithiumion battery electrolytes, and various other fields. The current primary industrial process employs a conventional sodium methoxide basic catalyst to produce DMC through the transesterification reaction between vinyl carbonate and methanol. However, the utilization of this catalyst presents several challenges during the process, including equipment corrosion, the generation of solid waste, susceptibility to deactivation, and complexities in separation and recovery. To address these limitations, a series of alkaline poly(ionic liquid)s, i.e. [DVBPIL][PHO], [DVCPIL][PHO], and [TBVPIL][PHO], with different crosslinking degrees and structures, were synthesized through the construction of cross-linked polymeric monomers and functionalization. These poly(ionic liquid)s exhibit cross-linked structures and controllable cationic and anionic characteristics. Research was conducted to investigate the effect of the crosslinking degree and structure on the catalytic performance of transesterification in synthesizing DMC. It was discovered that the appropriate cross-linking degree and structure of the [DVCPIL][PHO] catalyst resulted in a DMC yield of up to 80.6%. Furthermore, this catalyst material exhibited good stability, maintaining its catalytic activity after repeated use five times without significant changes. The results of this study demonstrate the potential for using alkaline poly(ionic liquid)s as a highly efficient and sustainable alternative to traditional catalysts for the transesterification synthesis of DMC.

Abstract ：
The synthesis of ethyl methyl carbonate (EMC) is of paramount importance for the lithium-ion battery industry as electrolytes. Herein, we present a series of swellable poly(ionic liquid)s (PILs) functionalized with phenol anions, aiming at inducing effective catalysis in EMC production through the transesterification of ethanol (EtOH) and dimethyl carbonate (DMC). The obtained PILs catalysts exhibit remarkable EMC yields of 57.0% and selectivity of 86.7%, coupled with robustness and facile reusability under mild conditions. By establishing a correlation between the swelling degree of PILs and the yield of EMC, and by a theoretical calculation on the energy and electrostatic potential changes of [CPIL-Tr]1[PhO] during its reaction with EtOH and DMC, we show that these impressive catalytic performances arise from efficient proton dissociation of EtOH by phenol anion and accelerated transportation of reactants by swelling cationic backbone. This research endeavors to provide an appealing platform for the industrial-scale production of EMC.

Abstract ：
Adsorptive removal of mercury ion from wastewater has become a hot topic due to the toxicity and persistence; acquiring adsorbent materials with high-capacity, rapid-kinetic, super-selective while low-cost features are highly demanded. Herein, based on the full functionality of collagen fiber (CF) from the leather waste, we proposed an innovative synthetic approach through exploiting amino-functionalized ZIF-7 (ZIF-7-NH2) as functional groups to facilely in-situ incorporate with CF, affording low-cost but effective adsorbent materials of CF/ZIF-7-NH2 composite maximizing both functions of CF and ZIF-7-NH2 in the Hg(II) capture. Remarkably, it exhibits an ultra-high capacity as high as 909.09 mg g-1, fast kinetics that could remove 99.01 % of 200 mg & sdot;L-1 within 20 min, and significant selectivity of SHg/M (KdHg/KdM) as large as 522-1017 over Mg2+, K+, Ca2+, Cd2+, and Mn2+. We understand such an impressive adsorption is contributed by the synergistic action between functional groups including on the CF and ZIF-7-NH2. This study offers an effective method for removing heavy metal ions, achieving efficient removal of Hg(II) ions for pollution control, and promoting the reuse of waste CF to reduce waste accumulation in various aspects.

Abstract ：
The significance of renewable energy sources underscores the importance of developing efficient battery technologies. Ethyl methyl carbonate (EMC), with its superior performance as an electrolyte, is widely utilized in lithium-ion batteries. However, the production of EMC through green transesterification of dimethyl carbonate (DMC) with ethanol encounters challenges due to low EMC selectivity and catalyst reusability issues. In this study, we present the initial instance of utilizing an imidazole-based ionic framework, [CPIL-M]n[PhO], which exhibits an interaction between its cationic backbone and basic anions. This interaction is specifically designed to catalyse the selective transformation of basic anions with suitable Lewis basicity in the production of EMC via transesterification. The introduction of N,N '-carbonyldiimidazole into the ionic framework allows for tunable modulation of Lewis basicity on an electronic level, enhancing catalytic activity without compromising selectivity. These innovative designs enable [CPIL-M]4[PhO] to exhibit remarkable performance, achieving 69.02% EMC yield and 90.19% selectivity, outperforming most reported catalysts. These findings could pave the way for the accelerated development of efficient catalysts for the sustainable production of EMC through transesterification methods in the future, thereby supporting the energy-efficient transition towards renewable energy sources. The ionic framework [CPIL-M]n[PhO] with feasible Lewis basicity toward transesterification of dimethyl carbonate with ethanol for highly selective production of ethyl methyl carbonate (EMC) is reported.
