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 ：
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 ：
Conjugated micro-mesoporous poly(aniline)s (CMPAs) synthesized through Buchwald-Hartwig coupling represent a cutting-edge material platform for selective sequestration of Hg (II) but suffer from moderate porosities and constrained availability of adsorption sites. Herein, we show a salt strategy for fine-tuning the porosity and Hg (II) adsorption performance of a series of S, N dual heteroatom functionalized CMPAs (CMPA-SN). The salt of NaF with appropriate dosage results in strikingly improved surface areas from 26 to 735 m2/g and intensified Hg (II) adsorption capacity from 311 mg/g to 649 mg/g. Moreover, CMPA-SN exhibits an efficient adsorption rate (h = 1250 mg/g/min) and excellent affinity with high Kd as high as 1.24 x 106 mL/g. We successfully correlate the adsorption capacity and surface area, and reveal the synergistic electron-sharing mechanism from N-containing ligands and in-situ decorated S heteroatoms, with 67.6 %/32.4 % contributions and Delta Eads = -0.419 eV/Delta Eads = -0.487 eV adsorption energy.

Abstract ：
In extreme environments, the simultaneous presence of mechanical impact and fire hazards poses significant challenges for single flexible polyurethane foam (FPUF) protective materials. To address these limitations, we developed an innovative multilayer coating structure for FPUF using a simple dip-drying method. This structure comprises a polydopamine (PDA) base layer, an intermediate layer containing ammonium polyphosphate (APP), carboxymethyl chitosan (CMC), and halloysite nanotubes (HNT), and a top layer of polydimethylsiloxane (PDMS). The multilayer coating significantly enhanced the cushioning and flame-retardant properties of FPUF. At a coating loading of 35 wt.%, the FPUF@PDA/A-C-H/PDMS exhibited a compressive strength 3.52 times higher than pure FPUF, with only a 10.2 % decrease after 100 compression cycles. The composite effectively dissipated 95.7 % of an impact energy of 1.22 J, achieving a 97.1 % impact force dissipation rate and significantly extending cushioning duration. The FPUF@PDA/A-C-H/PDMS demonstrated self-extinguishing properties after 10 s of exposure to a butane flame, maintaining structural integrity. Moreover, its peak heat release rate was reduced by 68.8 %. The multilayer coating also improved hydrophobicity and thermal insulation. This multifunctional foam composite shows great potential for enhancing the performances of FPUF in hazardous environments, offering robust protection in extreme conditions. © 2025 Elsevier Ltd

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 center dot g-(- 1) (at 318 K), with fast adsorption kinetic of 60 min, and excellent adsorption selectivity with Kd d = 4.69 x 104 4 mL center dot g-(- 1) under the temperature of 298 K, initial concentration of 50 mg center dot L-1,-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 center dot g-1.(-1 ). Furthermore, in continuous dynamic adsorption experiments, CMPA-F/CFM could treat up to 19.0 L center dot g(-1-) 1 of low-enriched uranium (LEU) solution (1 mg center dot L-1),-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.

Abstract ：
The presence of a considerable quantity of metal ions in N-methylpyrrolidone (NMP) applied for the cleaning of electronic devices, especially chips, results in a breakdown effect, thus affecting their overall durability and performance. Here, hydrogel that rich in O, N, and S active sites was prepared, which can effectively remove trace amounts of Cu (II) from N-methylpyrrolidone. The material was synthesized through a one-pot crosslinking and ion exchange method and is named SLH. The physicochemical properties and adsorption experiments were conducted. It was found that SLH-2 exhibited outstanding Langmuir maximum adsorption capacity of 136.99 mg/g at an initial Cu (II) concentration of 200 mg/L. By utilizing SLH-2 in electronic grade adsorption experiments, concentration of trace Cu (II) decreased from 12.3 μg/L to 5.39 μg/L. Additionally, concentration of Zn, Fe, Mg, and Ni significantly reduced to less than 1 μg/L, with –NH2 and –COOH playing crucial roles in the adsorption process. The research results indicate that predominant adsorption mechanisms are surface coordination and ion exchange. The adsorption energy between active functional groups and Cu (II) was calculated using density functional theory (DFT), revealing an affinity order of –COOH > –SO3H > –NH2 > –OH. This work not only developed an adsorbent for capturing trace Cu (II), but also provided new strategies for the removal of metal ions in wet chemicals. © 2024 Elsevier B.V.

Abstract ：
The coexistence of lead, zinc, and copper ions in wastewater constitutes an environmental challenge of pressing concern. This research delves into the preparation of innovative oxidation-doped conjugated microporous poly(aniline) frameworks, exploring their prospective efficacy in regulating lead ion adsorption from aqueous solutions. H2SO4-CMPTA demonstrates the capability to reach adsorption equilibrium within 15 min at a lead concentration of 50 ppm. Even at a lead concentration of 20 ppm, it still efficaciously attenuates these levels to sub-10 ppb, a value surpassing extant standard. H2SO4-CMPTA retains over 78.8% adsorption efficiency after six cycles. Analytical characterization coupled with computational calculations suggests that sulfate-coordinated nitrogen cationic structure plays a crucial role in adsorption. A deeper investigation reveals the cardinal role of electrostatic attraction and exclusive chelation adsorption underpinning the efficient capture of lead ions by doped sulfate ions. Intriguingly, in a mixed heavy metal solution containing lead, zinc, and copper ions, H2SO4-CMPTA exhibits an initial predilection toward zinc ions, yet an eventual ion-exchange adsorption gravitating toward lead ions was discerned, governed by the latter's superior binding energy. Our study elucidates a promising material as an efficacious tool for the remediation of aquatic environments tainted with lead contaminants.

Abstract ：
CO2 hydrogenation is an effective solution for direct ethanol production as it realizes a high-value utilization of waste CO2. As it requires a synergistic multi-step process of CO2 activation, asymmetric hydrogenation of CO, and precise coupling of C-C bonds, the design of highly active and selective catalysts for such procedures remains challenging. In this study, we prepared a series of La-doped CuFe catalysts using a simple and green solvent-free ball milling method to accelerate the rate of CO2 hydrogenation to ethanol generation. HRTEM, in situ XRD, EPR, and CO2-TPD analyses indicated that the doping of moderate amounts of La can significantly improve the dispersion of the Cu and Fe species, enhance the interaction between the CuFe species, decrease the reduction temperatures of CuO and Fe2O3, promote the formation of oxygen vacancies during the reaction process, and enhance CO2 adsorption and activation ability. DFT calculations, XPS, in situ FTIR, and CO-TPSR-MS analyses indicated that the transfer of electrons from the Fe to La species decreased their electron cloud densities, weakened the bridge type adsorption of CO, enhanced the linear adsorption of CO, and optimized the ratio of the dissociative and non-dissociative adsorption of CO intermediates, which ultimately resulted in a better matching of the rates of generation of CHx* and C(H)O* intermediates. The occurrence of C-C coupling at the abundant Cu0-Fe5C2 interface promoted the highly efficient synthesis of ethanol, achieving yields as high as 13.5% over the 5La-CuFeOx catalyst, ranking the top level among the reported catalysts in the literature. This study presents a feasible strategy for the targeted regulation of multicomponent active centers.

Abstract ：
Membrane separation strategies offer promising platform for the emulsion separation.However,the low mechanical strength of membrane separation layers and the trade-off between separation flux and ef-ficiency present significant challenges.In this study,we report a CFM@UiO-66-NH2 membrane with high separation flux,efficiency and stability,through utilizing a robust anti-abrasion collagen fiber membrane(CFM)as the multifunctional support and UiO-66-NH2 by an in-situ growth as the separation layer.The high mechanical strength of the CFM compensated for the weakness of the separation layer,while the charge-breaking effect of UiO-66-NH2,along with the size sieving of its constituent separating layers and the capillary effect of the collagen fibers,contributed to the potential for efficient separation.Addi-tionally,the CFM@UiO-66-NH2 membrane exhibited superhydrophilic properties,making it suitable for separating oil-in-water microemulsions and nanoemulsions stabilized by anionic surfactants.The membrane demonstrated remarkable separation efficiencies of up to 99.960％and a separation flux of 370.05 L·m-2·h-1.Moreover,it exhibits stability,durability,and abrasion resistance,maintaining excellent separation performance even when exposed to strong acids and alkalis without any damage to its structure and performance.After six cycles of reuse,it achieved a separation flux of 417.97 L·m-2·h-1 and a separation efficiency of 99.747％.Furthermore,after undergoing 500 cycles of strong abrasion,the separation flux remained at 124.39 Lm-2·h-1,with a separation efficiency of 99.992％.These properties make it suitable for the long-term use in harsh operating environments.We attribute these properties to the electrostatic effect resulting from the amino group on UiO-66-NH2 and its in-situ growth on the CFM,which forms a size-screening separation layer.Our work highlights the potential of the CFM@UiO-66-NH2 membrane as an environmentally friendly size-screening material for the efficient emulsion wastewater separation.
