Abstract

Layered double hydroxides (LDHs) can be used as catalysts and adsorbents due to their high stability, safety, and reusability. The preparation of modified LDHs mainly includes coprecipitation, hydrothermal, ion exchange, calcination recovery, and sol–gel methods. LDH-based materials have high anion exchange capacity, good thermal stability, and a large specific surface area, which can effectively adsorb and remove heavy metal ions, inorganic anions, organic pollutants, and oil pollutants from wastewater. Additionally, they are heterogeneous catalysts and have excellent catalytic effect in the Fenton system, persulfate-based advanced oxidation processes, and electrocatalytic system. This review ends with a discussion of the challenges and future trends of the application of LDHs in wastewater treatment.

摘要：生物炭负载零价铁（ZVI/BC）在高级氧化处理有机污水领域具有广阔的应用前景，但通过球磨改性载体生物炭，进而提升ZVI/BC的催化效能尚缺乏系统研究. 首先通过球磨处理得到系列球磨生物炭，再利用水热法制备球磨生物炭负载零价铁（ZVI/0.25BC40-0.5），采用SEM、TEM、EDS Mapping、XRD、BET和FTIR对复合材料的理化性质进行表征. 研究结果表明，ZVI/0.25BC40-0.5/PMS体系可实现四环素（TC）的高效降解，当催化剂、PMS和TC的浓度分别为20 mg∙L⁻¹、1 mmol∙L⁻¹和20 mg∙L⁻¹，pH = 5.0，反应时间为30 min时，TC的降解效率可达87.1%；催化剂和PMS浓度的增加，均能够促进TC在ZVI/0.25BC40-0.5/PMS体系中的降解；水体中共存阴离子和腐殖酸对反应体系影响较小；自由基猝灭实验和EPR分析证实ZVI/0.25BC40-0.5/PMS体系中存在自由基途径和非自由基途径，其中•OH起主要作用；综合XPS结果说明C=O和Fe物种是ZVI/0.25BC40-0.5表面主要的催化位点.

2021年3月4日，朱日欣同学的论文“Mechanochemical synthesis of Ca-Al-Fe layered double hydroxide for efficient phosphate removal from aqueous solution”被Materials Express期刊接收。

Abstract

A simple mechanochemical method was utilized to synthesize Ca–Al–Fe layered double hydroxide (CAF-LDH) and the Ca-Al-Fe-layered double oxide (CAF-LDO) was obtained by calcining CAF-LDH at 500 ^oC. From the results of XRD, FTIR, SEM and zeta potential, both CAF-LDH and CAF-LDO contained abundant functional groups, such as –OH, NO₃⁻ and CO₃²⁻. Over 90% removal efficiency for 25.0 mg/L phosphate was achieved with CAF-LDH and CAF-LDO at pH 3–10. The adsorption process quickly reached equilibrium within only 30 min. The isothermal and kinetics data better fit the Langmuir model (LM) and the pseudo-second-order (PSO) model, respectively. Based on the adsorption tests, zeta potential and FTIR, the interaction mechanisms were mainly electrostatic attraction and inner-sphere surface complexation (ISSC). In addition, CAF-LDH and CAF-LDO presented efficient regeneration, reusability, selectivity and potential application to remove phosphate in the water environment.

摘要：水体中难降解有机物对人体和生态环境存在潜在威胁，开发高效、环保和低成本的催化体系对修复此类废水具有重要意义。生物炭基材料-过硫酸盐高级氧化体系在污水处理领域有广阔的应用前景，为了进一步明确生物炭基材料活化PMS(过一硫酸盐)降解有机污染物的性能及微观机制，综述了生物炭、(非)金属元素掺杂生物炭和金属氧化物-生物炭复合材料3种典型生物炭基材料活化PMS降解有机污染物的催化活性及界面反应机制。研究表明：生物炭基材料表面催化位点(如含氧官能团、缺陷、持久性自由基、金属原子等)可通过自由基或非自由基方式促进PMS活化，进而促进SO₄^-•(硫酸根自由基)、•OH(羟基自由基)和O₂^-•(超氧自由基)等活性物种的产生，最终增加相应体系的催化活性；使用(非)金属元素掺杂或者负载金属(氧化物)能够显著改变生物炭电荷分布和活性位点，进而增加生物炭基材料的催化活性。但目前的研究仍存在一些不足，如多种活性位点在生物炭基材料活化PMS过程中的协同作用机制尚不明确，杂原子共掺杂生物炭或生物炭负载单原子催化剂在PMS体系中的催化活性及机制、自由基/非自由基方式的协同作用机制也兹待研究。此外，污染物自身结构特性对生物炭基材料催化活性的影响机制也有待进一步探讨。

论文链接：http://kns.cnki.net/kcms/detail/37.1316.tu.20200601.1258.001.html

       摘要：磁性Fe₃O₄纳米材料由于其稳定性、表面界面效应、量子尺寸效应、电磁特性等独特的物理和化学特性，在污水处理、磁共振、药物载体等方面表现出潜在的应用价值。本文中综述了磁性Fe₃O₄的制备方法（共沉淀法、水热法、溶剂热法、微乳液法、溶胶－凝胶法等），评价了表面改性和合成复合材料对提高其吸附效果的影响，总结了其在去除废水中金属离子、难降解有机污染物和其他污染物方面的应用和性能。磁性Fe₃O₄的制备方法各有优点，可以根据简便程度、粒径分布、分散程度等需要制备具有不同性质和使用性能的改性Fe₃O₄和复合材料。在水处理应用方面，Fe₃O₄磁性材料具有吸附性能好、化学稳定性强、便于分离和回收等优点。但目前的研究存在磁性Fe₃O₄纳米材料的制备局限于实验室、针对实际废水应用偏少等不足。今后应从寻找更经济绿色且可产业化的制备方法、进一步提高去除水中污染物的能力和回收利用性能、扩大应用领域等方面进行深入研究。

论文链接：https://rdcu.be/b4aYz

Abstract

To evaluate the adsorption mechanism and performance of phosphate onto the composite of low-cost biochar and iron oxide, four biochar–iron oxides, namely biochar–magnetite (BC-M), biochar–ferrihydrite (BC-F), biochar–goethite (BC-G), and biochar– hematite (BC-H), were prepared by fabricating iron oxide to porous biochar. The biochar–iron oxides had huge surface areas of 691–864 m2/g and average pore diameters of 3.4–4.0 nm. Based on the characterization analysis of FTIR, XRD, XPS, and zeta potential, the interactions of electrostatic attraction, ligand exchange, and deposition dominated the phosphate adsorption onto biochar–iron oxides. The maximum adsorption capacity of phosphate followed the order of BC-G > BC-F > BC-H > BC-M. The isotherm data of BC-M and BC-H were well fitted by the Langmuir and Freundlich models, while those of BC-G and BC-F followed the Langmuir model. In addition, BC-M, BC-F, BC-G, and BC-H owned excellent regeneration ability and adsorption performance in practical (simulated) wastewater environment. Then the biochar–iron oxides exerted extensive and satisfactory prospect in wastewater remediation and recycling application in soil.

2019年8月16日，以“聚力污染防治攻坚战、引领环境科学新时代”为主题的第十届全国环境化学大会在南开大学开幕。包括15位国内院士，12位美国工程院、加拿大皇家科学院、韩国国家工程院、欧洲科学及艺术院、爱尔兰科学院院士，300余名国家“杰青”、教育部“长江学者”等获得者，共计7000余位环境化学领域专家学者和研究生齐聚南开大学，交流环境化学研究最新进展，探讨学科发展未来方向。

闫良国教授带领硕士研究生参加了本次大会。杨艳亭同学在环境材料与催化分会场做了“磁性LDH-TiO2复合材料高效去除水中高浓度Cr(VI)研究”的报告，李静、张照然、侯太磊在研究生论坛分别做了“EDTA插层LDH吸附六价铬的机理研究”、“生物炭/焙烧水滑石复合材料对水中磷酸盐的去除研究”和“磁性水滑石高效去除水中的氧化石墨烯及其煅烧产物重金属离子的二次吸附”三场报告。部分同学的研究成果在会议上以墙报形式展出，分别是杨艳亭“Synergistic adsorption and photocatalytic reduction of Cr(VI) using Zn-Al-layered double hydroxide and TiO2 composites”、张照然“生物炭/铁氧化物复合材料的制备及去除水中磷酸盐研究”、张雪“L-半胱氨酸插层水滑石对水中重金属的去除研究”、李静“丙烯酰胺改性LDH对六价铬和刚果红的共同吸附和机理研究”、杨艳亭“黑炭物质（BC）对1-萘胺的转化行为的影响研究”。

通过本次会议，课题组成员了解了国内外环境领域的最新研究进展，学习了相关领域知识和技术，为课题组的进一步发展和创新开拓了新的思路。
