Abstract ：
Developing the Co-based catalysts with high reactivity for the sulfate radical (SO4−·)–based advanced oxidation processes (SR-AOPs) has been attracting numerous attentions. To improve the peroxymonosulfate (PMS) activation process, a novel Co-based catalyst simultaneously modified by bamboo carbon (BC) and vanadium (V@CoO-BC) was fabricated through a simple solvothermal method. The atenolol (ATL) degradation experiments in V@CoO-BC/PMS system showed that the obtained V@CoO-BC exhibited much higher performance on PMS activation than pure CoO, and the V@CoO-BC/PMS system could fully degrade ATL within 5 min via the destruction of both radicals (SO4−· and O2−··) and non-radicals (1O2). The quenching experiments and electrochemical tests revealed that the enhancing mechanism of bamboo carbon and V modification involved four aspects: (i) promoting the PMS and Co ion adsorption on the surface of V@CoO-BC; (ii) enhancing the electron transfer efficiency between V@CoO-BC and PMS; (iii) activating PMS with V3+ species; (iv) accelerating the circulation of Co2+ and Co3+, leading to the enhanced yield of reactive oxygen species (ROS). Furthermore, the V@CoO-BC/PMS system also exhibited satisfactory stability under broad pH (3–9) and good efficiency in the presence of co-existing components (HCO3−, NO3−, Cl−, and HA) in water. This study provides new insights to designing high-performance, environment-friendly bimetal catalysts and some basis for the remediation of antibiotic contaminants with SR-AOPs. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.

Abstract ：
The photoresponsive adsorption materials are of great significance to the light controlled release performance of pollutants and the development of green regeneration of adsorption materials. A photoresponsive cellulose based imprinted adsorbent（Cell-AB-MIP）was synthesized by surface-initiates atom transfer radical polymerization （SI-ATRP） using cellulose as raw material，azobenzene derivatives as functional monomers，and the typical pesticide residues 2，4-D as template. The synthetic conditions were optimized by single factor experiment ，and the structure and performance of the material was analyzed by some characterization methods. The results show that the surface of Cell-AB-MIP contains abundant functional groups（—COOH，N=N，etc.），which have a high specific recognition effect for 2，4-D. The introduction of azobenzene group makes Cell-AB-MIP have excellent photo-induced regeneration performance. The azobenzene group on Cell-AB-MIP surface changes from trans-configuration to cisconfiguration under UV irradiation，then changing the binding affinity of adsorbent for pollutants，thus realizing green regeneration via UV-light. The desorption efficiency can reach 72. 22% in methanol medium under UV light irradiation. After 5 times of cycle，the adsorption percentage to 2，4-D still remains 83. 47%. The analysis results of SEM and EA confirm that the adsorbed pollutants can be separated from the surface of the adsorbent after UV irradiation，completing the regeneration process. © 2024 Beijing Institute of Aeronautical Materials (BIAM).

Abstract ：
An annual production of about 500 million tons of household food waste (HFW) has been documented, resulting in significant implications for human health and the environment in the absence of appropriate treatment. The anaerobic fermentation of HFW in an open system offers the potential to recover high value-added products, lactic acid (LA), thereby simultaneously addressing waste treatment and enhancing resource recovery efficiency. Most of LA fermentation studies have been conducted under mesophilic and thermophilic conditions, with limited research on the production of LA through anaerobic fermentation under hyperthermophilic conditions. This study aimed to produce LA through anaerobic fermentation from HFW under hyperthermophilic conditions (70 +/- 1 degrees C), while varying pH values (5.0 +/- 0.1, 7.0 +/- 0.1, and 9.0 +/- 0.1), and compare the results with LA production under mesophilic (35 +/- 1 degrees C) and thermophilic (52 +/- 1 degrees C) conditions. The findings of this study indicated that the combination of hyperthermophilic conditions and a neutral pH (pH7_70) yielded the highest concentration of LA, measuring at 17.75 +/- 1.51 g/L. The mechanism underlying the high yield of LA at 70 degrees C was elucidated through the combined analysis of organics dissolution, enzymes activities, and 16S rRNA microbiome sequencing.

Abstract ：
Developing adsorbents with high performance and long service life for effective extracting the trace organochlorine pesticides (OCPs) from real water is attracting numerous attentions. Herein, a self-standing covalent organic framework (COF-TpPa) membrane with fiber morphology was successfully synthesized by using electrospun nanofiber membranes as template and employed as solid-phase microextraction (SPME) coating for ultra-high sensitivity extraction and analysis of trace OCPs in water. The as-synthesized COF-TpPa membrane exhibited a high specific surface area (800.83 m(2) g(-1)), stable nanofibrous structure, and excellent chemical and thermal stability. Based on the COF-TpPa membrane, a new SPME analytical method in conjunction with gas chromatography-mass spectrometry (GC-MS) was established. This proposed method possessed favorable linearity in concentration of 0.05-2000 ng L-1, high sensitivity with enrichment factors ranging from 2175 to 5846, low limits of detection (0.001-0.150 ng L-1), satisfactory precision (RSD < 10 %), and excellent repeatability (>150 cycles), which was better than most of the reported works. Additionally, the density functional theory (DFT) calculations and XPS results demonstrated that the outstanding enrichment performance of the COF-TpPa membrane was owing to synergistic effect of pi-pi stacking effects, high specific surface area and hydrogen bonding. This work will expect to extend the applications of COF membrane to captures trace organic pollutants in complex environmental water, as well as offer a multiscale interpretation for the design of effective adsorbents.

Developing the transition metal catalysts with high reactivity for the sulfate radical (SO4 -center dot) based advanced oxidation processes (SR-AOPs) has been attracting numerous attentions. To improve the peroxymonosulfate (PMS) activation process mediated by Co-based catalysts, a vanadium-cobalt bimetallic catalyst (V@CoO) was fabricated by modification vanadium through a simple solvothermal method. The pollutants degradation experiments showed that the obtained V@CoO exhibited much higher performance on PMS activation (5.55-8.33 times larger of apparent rate constants) than pure CoO, and the V@CoO/PMS system could quickly degrade various organic contaminants within 5 min under the attack of both radicals (SO4 -center dot and O2-center dot) and non-radicals (1O2). The density functional theory (DFT) calculations and electrochemical tests revealed that the enhancing mechanism of V modification involved four aspects: (i) promoting the PMS adsorption on the surface of V@CoO; (ii) enhancing the electron transfer efficiency between V@CoO and PMS; (iii) activating PMS with V3+ and V4+ species; (iv) accelerating the circulation of Co2+ and Co3+, leading to the promotion on the production of reactive oxygen species (ROS). Furthermore, the V@CoO/PMS system also exhibited satisfactory stability in a broad pH range and good efficiency in the presence of co-existing components (HCO3-, NO3-, PO43- , Cl- and HA) in water. This study will provide new insights to designing high-performance, environment-friendly bimetal catalysts and some basis for the remediation of organic contaminants with SR-AOPs.

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 ：
Detecting trace endocrine disruptors in water is crucial for evaluating the water quality. In this work, a innovative modified polyacrylonitrile@cyanuric chloride-triphenylphosphine nanofiber membrane (PAN@CC-TPS) was prepared by in situ growing triazine porous organic polymers on the polyacrylonitrile (PAN) nanofibers, and used in the dispersive solid phase extraction (DSPE) to enrich trace nitrobenzene phenols (NPs) in water. The resluted PAN@CC-TPS nanofiber membrane consisted of numerous PAN nanofibers cover with CC-TPS solid spheres (similar to 2.50 mu m) and owned abundant functional groups, excellent enrichment performance and good stability. In addition, the method based on PAN@CC-TPS displayed outstanding capacity in detecting the trace nitrobenzene phenols, with 0.50-1.00 mu g/L of the quantification, 0.10-0.80 mu g/L of the detection limit, 85.35-113.55 % of the recovery efficiency, and 98.08-103.02 of the enrichment factor, which was comparable to most materials. Meanwhile, when PAN@CC-TPS was adopted in the real water samples (sea water and river water), the high enrichment factors and recovery percentages strongly confirmed the feasibility of PAN@CC-TPS for enriching and detecting the trace NPs. Besides, the related mechanism of extracting NPs on PAN@CC-TPS mainly involved the synergistic effect of hydrogen bonding, pi-pi stacking and hydrophobic effect.

光响应性吸附材料对污染物的光控释放性能，对发展吸附材料的绿色再生具有重要的意义。以纤维素为原料，偶氮苯衍生物为功能单体，以典型农药残留2,4-D为模板，采用表面引发原子转移自由基聚合（SI-ATRP）制备光响应纤维素印迹吸附剂（Cell-AB-MIP）。通过单因素实验对材料的制备条件进行优选，采用多种表征手段对材料结构和性能进行分析。结果表明：Cell-AB-MIP表面含有丰富的官能团（—COOH,N=N等），对2,4-D具有较高的特异性识别作用；偶氮苯基团的引入使得Cell-AB-MIP具备优异的光再生性能。经过紫外光照射后，Cell-AB-MIP上的偶氮苯基团将从反式构型转变为顺式构型，从而改变吸附剂对污染物的吸附亲和力，实现光控条件下的清洁脱附。在甲醇介质中光照解吸效率可达72.22%，经过5次光循环后对2,4-D的吸附百分比仍可达到83.47%;SEM及EA分析结果证实了吸附剂经紫外光照射后污染物可从吸附剂表面脱离，完成吸附剂的再生过程。
