The organic herbicides of chlorophenoxyacetic acids, including 2,4-dichlorophenoxyacetic acid (2,4-D) and 2-methyl-4-chlorophenoxyacetic acid (MCPA), have posed serious threats to aquatic ecosystems and human health due to extensive use, high solubility and degradation-resistant. In this study, the efficient adsorbent (MOF-808) was synthesized through solvothermal synthesis method and further evaluated for the adsorption performances of 2,4-D and MCPA. Results showed that MOF-808 exhibited the Type I nitrogen adsorption–desorption isotherm with a specific surface area of 2,155 m²·g⁻¹, pore volume of 0.59 cm³·g⁻¹ and pore size of 1.41 nm. It was suggested that the pseudo-second-order and Langmuir model were much better to illustrate the adsorption performances of MOF-808 for both 2,4-D and MCPA, and the maximum adsorption capacities of 793 and 775 mg·g⁻¹ were achieved, respectively; besides, the adsorption processes were spontaneous and primarily driven by chemical adsorption with contributions from physical-chemical adsorption. Additionally, the adsorption capacities for 2,4-D and MCPA were decreased with the increasing of pH and cations concentrations; the optimal pH was 3.0 for 2,4-D and 4.0 for MCPA, and the effects of four cations on pesticides adsorption followed the order of Ca²⁺ > Mg²⁺ > Na⁺ > K⁺. Reuse experiments demonstrated that MOF-808 could retain a high removal rate of 95.9 % (2,4-D) and 95.8 % (MCPA) at the fifth cycle. The spectral analysis revealed that the adsorption mechanisms of 2,4-D and MCPA by MOF-808 involved electrostatic interactions, π-π interactions, hydrogen bonding, and complexation. In conclusion, the well-defined physicochemical properties and outstanding adsorption performance of the synthesized MOF-808 may provide a potential application for the removal of chlorophenoxyacetic acid herbicides from real wastewater.

The advancement of photocatalytic degradation to eliminate toxic organic pollutants from wastewater has progressed rapidly. Although numerous photocatalysts have been reported, there remains a huge demand of appropriate photocatalyst materials that demonstrates remarkable photocatalytic efficiency. The prime target of this study is to explore a new way of fabricating low cost and environmentally friendly carboxylated functionalized jute stick carbon based ZnO photocatalyst for eliminating organic dyes from aqueous solution. In this study, nanostructure semiconductor photocatalyst undecorated ZnO, carboxylated activated jute stick carbon based ZnO (ZnO/JSAC-COO^–), and reduced graphene oxide based ZnO (ZnO-rGO) composites were fabricated by a facile low-cost hydrothermal process. The crystallinity, morphology, particle size, chemical characterization and optical properties were characterized by X-ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM), Fourier Transform Infrared Spectroscopy (FT-IR), Raman Spectroscopy and UV–visible spectroscopy, respectively. The XRD results showed that all XRD patterns of photocatalyst have a wurtzite, hexagonal structure of ZnO without any impurities. The catalytic activities of fabricated samples were examined by the photodegradation of methylene blue dye in water under UV light. The photocatalyst ZnO/JSAC-COO^– composite exhibited enhanced photocatalytic activity than ZnO and ZnO-rGO catalysts. The highest degradation and mineralization were obtained 97.57 % for methylene blue over ZnO/JSAC-COO^– within 300 min UV light irradiation. Photodegradation results suggest that ZnO/JSAC-COO^– composite prepared by hydrothermal method has a potential application in photo-catalysis leading to the efficient removal of harmful organic pollutants from the wastewater.

This study focuses on an investigation of the corrosion inhibition behavior of Syzygium polyanthum (Wight) Walp. leaf extract (SPWE) of carbon steel in 1.0 M hydrochloric acid medium. Electrochemical methods demonstrated a corrosion inhibition efficiency of 94.65 ± 0.94 % when 2000 ppm extract is added to the corrosive solution. Furthermore, surface analysis results indicated that with the absence of an inhibitor, the steel surface suffered severe corrosion, while the corrosion density was slow, and a film was observed on the surface after applying the SPWE into a corrosive environment. The film formed by the chemical and physical adsorption of compounds such as polyphenol, flavonoid, alkaloid, and tannin onto the carbon steel surface has been qualitatively and quantitatively analyzed in this study. Notably, increased immersion time and reaction temperature led to significant desorption of molecules, reflecting characteristic of physical adsorption. However, the corrosion inhibition efficiency of SPWE remained effective, particularly within the temperature range of 25–35 °C. Therefore, this study provides an efficient inhibitor for carbon steel corrosion in 1.0 M hydrochloric acidic environment that could be possibly added to the corrosion inhibitor system.

Magnetron-sputtered membranes have been an interesting candidate for water and gas treatment applications because of their controllable thickness, chemical compositions, crystalline structure, and other surface properties. Using magnetron sputtering (MS) as a reproducible and scalable deposition technique, membranes can be directed fabricated or modified through deposition of a thin layer on a support layer. The fundamental concepts, detailed processing mechanism, and various types of this technique are first outlined. Then, the applications of this technique in depositing thin films, mainly originating from polymers, metal(loid)s, oxides, and carbon, on membrane supports are briefly discussed. The next focus is on recent progress in this field by reporting the performance of MS-based developed membranes in both water and gas treatment processes, which provides a comparative study in terms of filtration efficiency. Finally, the current challenges and future directions are briefly provided for the development of next-generation magnetron-sputtered membranes.

Photocatalysis technology has been widely studied for treating Cr(VI) pollution in water and constructing heterogeneous structures presents a compelling approach to enhance the efficiency of Cr(VI) treatment. Pitifully, solely utilizing heterostructure, especially random composites of heterogeneous photocatalysts, often falls short of effectively enhancing the separation efficiency of photogenerated carriers. Furthermore, most photocatalysts interact weakly with the Cr(VI) anions, greatly reducing the utilization efficiency of photogenerated carriers. Herein, pyridine-based conjugated imprinted polymer (CIP) photocatalyst was precisely coated on urchin-like TiO₂ using an in-situ condensation approach, forming a compact core–shell structure of organic/inorganic heterojunction. On the one hand, the compact heterojunction structure of the core–shell effectively improved the separation efficiency of photogenerated carriers. On the other hand, CIP enhanced the adsorption between the photocatalyst and Cr(VI), effectively improving the utilization efficiency of photogenerated carriers. Due to the collaborative effects of selective adsorption and core–shell heterojunction photocatalysis, the photocatalyst demonstrated remarkable performance in eliminating Cr(VI). For high concentration Cr(VI) pollution of 100 ppm, complete elimination could be achieved within 90 min. This research presented an innovative and efficient approach for the precise synthesis of photocatalysts.

光催化技术已被广泛用于处理水中的六（Cr）污染，而构建异质结构则是提高六（Cr）处理效率的有效方法。遗憾的是，仅仅利用异质结构，特别是异质光催化剂的随机复合材料，往往不能有效提高光生载体的分离效率。此外，大多数光催化剂与六价铬阴离子的相互作用较弱，大大降低了光生载体的利用效率。本文采用原位缩合方法，将吡啶基共轭印迹聚合物（CIP）光催化剂精确包覆在海胆状氧化钛上，形成了有机/无机异质结的紧凑型核壳结构。一方面，紧凑的核壳异质结结构有效提高了光生载流子的分离效率。另一方面，CIP 增强了光催化剂与六价铬之间的吸附作用，有效提高了光生载流子的利用效率。由于选择性吸附和核壳异质结光催化的协同作用，该光催化剂在消除六价铬方面表现出显著的性能。对于 100 ppm 的高浓度六价铬污染，可在 90 分钟内实现完全消除。这项研究为精确合成光催化剂提供了一种创新而高效的方法。

Li[Ni_xMn_yCo_1-x-y]O₂ (NCM) has attracted considerable attention as a cathode material because of its excellent electrochemical performance; however, practical application of NCM is challenging owing to side reactions in the electrolyte and structural changes. In this study, we manufactured NCM electrodes with mixtures of Super-P and vapor-grown carbon fiber (VGCF) as conductive additives at different ratios (Super-P/VGCF=2/8 (S2V8), 5/5 (S5V5), and 8/2 (S8V2)) and investigated the effect of the ratio of the conductive additives on NCM electrode performance. Simply changing the ratio of the conductive additives without modifying the NCM active materials substantially altered the electrochemical performance. Using a Super-P/VGCF mixture at an appropriate ratio (5/5, w/w) forms a conductive network throughout the NCM active materials, improving the electrical conductivity and enabling uniform activation across the range of NCM particles. Consequently, for S5V5, the anisotropic volume changes of the NCM primary particles became uniform, resulting in structural stability of the secondary NCM particles during charging and discharging.

Li[NiMnCo]O（NCM）作为一种阴极材料，因其优异的电化学性能而备受关注；然而，由于电解质中的副反应和结构变化，NCM 的实际应用具有挑战性。在本研究中，我们以 Super-P 和气相生长碳纤维 (VGCF) 的混合物作为导电添加剂，以不同的比例（Super-P/VGCF=2/8 (S2V8)、5/5 (S5V5) 和 8/2 (S8V2)）制造了 NCM 电极，并研究了导电添加剂的比例对 NCM 电极性能的影响。在不改变 NCM 活性材料的情况下，仅改变导电添加剂的比例就会大大改变电化学性能。使用适当比例（5/5，w/w）的 Super-P/VGCF 混合物可在整个 NCM 活性材料中形成导电网络，从而提高导电性，并使整个 NCM 颗粒范围内的活化均匀一致。因此，对于 S5V5，NCM 初级粒子的各向异性体积变化变得均匀，从而使次级 NCM 粒子在充放电过程中保持结构稳定。

Waste sulfuric acid of alkylation (WSAA) poses a challenge in industrial alkylation oil production due to its substantial yield and high treatment costs. This study introduces a novel hydrothermal method that ingeniously couples the treatment of WSAA with the synthesis of high-quality carbon quantum dots (CQDs), offering a cost-effective and controllable approach. Through this method, the particle size and surface functional groups of the resulting CQDs can be precisely regulated. The average particle size tunes from 17.97 nm to 2.42 nm via increasing the hydrothermal temperature, and nitrogen-containing groups can be introduced through adding nitrogen sources during hydrothermal process. The prepared CQDs exhibit notable performance in photocatalysis and heavy metal detection, such as CQDs modified graphite carbon nitride has improved photocatalytic degradation ability and Hg (II) detection ability. Additionally, the environmental impact of the proposed method is substantially minimized, demonstrating a smaller footprint on ecosystems compared to conventional industrial disposal processes. Moreover, the economic cost associated with the method is significantly reduced by approximately 48.4 %, further highlighting its efficiency. Utilizing WSAA as a raw material for CQDs not only facilitates the recycling and sustainable utilization of waste but also enables low-cost production of high-performance carbon materials, presenting a mutually beneficial approach.

烷基化废硫酸（WSAA）因其产量大、处理成本高而成为工业烷基化油生产中的难题。本研究介绍了一种新颖的水热法，该方法巧妙地将处理 WSAA 与合成高质量碳量子点（CQDs）结合起来，提供了一种具有成本效益且可控的方法。通过这种方法，可以精确调节 CQDs 的粒度和表面官能团。通过提高水热温度，平均粒径可从 17.97 纳米调谐到 2.42 纳米；在水热过程中添加氮源可引入含氮基团。所制备的 CQDs 在光催化和重金属检测方面表现出显著的性能，如 CQDs 修饰的氮化石墨具有更好的光催化降解能力和 Hg (II) 检测能力。此外，与传统的工业处理工艺相比，该方法对环境的影响大大降低，对生态系统的影响也更小。此外，与该方法相关的经济成本大幅降低了约 48.4%，进一步凸显了其效率。利用 WSAA 作为 CQD 的原材料，不仅有利于废物的回收和可持续利用，还能以低成本生产高性能碳材料，是一种互惠互利的方法。

SiOx/C electrodes are widely used due to their high lithium storage capacities and cycling stabilities. However, the SiOx/C electrode exhibits large volume expansion and unstable SEI layer formation during cycling. In this work, a carbon tetrafluoride (CF₄) plasma was used to introduce C-F bonds onto the electrode surface to form a LiF-based SEI layer on a SiOx/C electrode (SGE) to improve its mechanical and electrochemical properties. The fluorinated SiOx/C electrode (FSGE) subjected to the CF₄ plasma treatment for 10 min mitigated 2.5 times the volume expansion compared to the SGE by forming a LiF-based SEI layer to increase the mechanical properties. This mitigation of FSGE volume expansion resulted in excellent long-term cycling stability of 83 % for 100 cycles (1C). In addition, the LiF-based SEI layer formed on the FSGE increased the mobility of Li ions, resulting in 1.2 times better cycle stability than that of SGE at a high rate (10C). Thus, the improvement in the electrochemical performance achieved by reducing the volume expansion of SiOx in the electrode and enhancing the Li-ion conductivity was attributed to the stable LiF SEI layer formed with semi-ionic CF bonds introduced by the CF₄ plasma.

SiOx/C 电极具有很高的锂存储容量和循环稳定性，因此被广泛使用。然而，SiOx/C 电极在循环过程中会出现较大的体积膨胀和不稳定的 SEI 层形成。在这项工作中，使用四氟化碳（CF）等离子体在电极表面引入 C-F 键，在 SiOx/C 电极（SGE）上形成锂基 SEI 层，以改善其机械和电化学性能。氟化 SiOx/C 电极（FSGE）经 CF 等离子处理 10 分钟后，通过形成锂基 SEI 层，体积膨胀比 SGE 减小了 2.5 倍，从而提高了机械性能。减轻了 FSGE 体积膨胀后，100 次循环 (1C) 的长期循环稳定性高达 83%。此外，在 FSGE 上形成的 LiF 基 SEI 层提高了锂离子的迁移率，使其在高循环速率（10C）下的循环稳定性比 SGE 高出 1.2 倍。因此，通过降低电极中 SiOx 的体积膨胀和提高锂离子传导性而实现的电化学性能的改善归功于由 CF 等离子体引入的半离子 CF 键形成的稳定的 LiF SEI 层。

This paper proposes an innovative technology for desalinating brackish water and seawater using a multi-tube type falling film distillation column integrated with a biphasic thermosyphon. Based on the literature survey, this proposal has not been previously explored. In this study, the viability of the pilot-scale application of this technology for desalination was tested, and the process performance was evaluated in terms of distillate flow rate, salinity removal, and energy consumption, considering different experimental conditions. Synthetic solutions containing 10.0 and 35.0 g/L of sodium chloride were used to simulate brackish water and seawater salinities, respectively. The thermal desalination pilot plant integrating a compact falling film distillation column and a biphasic thermosyphon demonstrated high effectiveness, consistently producing desalinated water with a conductivity below 10 μS cm⁻¹. Considering both concentrations, the optimal condition for desalinated water production was a feed temperature of 85 °C, a vapor chamber temperature of 121 °C, and an energy consumption of 16 kW. This new technological option’s energy consumption is approximately 33 % lower than that of a simulated flash distillation column operating under similar conditions. In conclusion, this study presents promising results, establishing falling film distillation technology as a viable alternative for desalinating brackish water and seawater.

本文提出了一种利用多管式降膜式蒸馏塔与双相热流器相结合来淡化苦咸水和海水的创新技术。根据文献调查，这一建议以前从未被探讨过。本研究测试了该技术在海水淡化中试规模应用的可行性，并根据不同的实验条件，从蒸馏物流速、盐度去除率和能耗等方面评估了工艺性能。合成溶液中分别含有 10.0 和 35.0 克/升的氯化钠，用于模拟苦咸水和海水的盐度。集成了紧凑型降膜蒸馏塔和双相热吸附器的热淡化中试设备表现出很高的效率，能稳定地生产出电导率低于 10 μS cm 的淡化水。考虑到两种浓度，生产淡化水的最佳条件是进水温度为 85 °C，蒸汽室温度为 121 °C，能耗为 16 千瓦。这种新技术方案的能耗比模拟闪蒸塔在类似条件下的能耗低约 33%。总之，这项研究取得了可喜的成果，将降膜式蒸馏技术确立为淡化苦咸水和海水的可行替代技术。

The corrosion of steel construction in marine environments faces severe corrosion threats, and coatings based on nanofillers are an effective strategy for steel corrosion protection. However, the related studies of the anti-corrosion coatings based on quantum dots are still poor. In this work, CuS and ZnS quantum dots (QD) were initially synthesized, and epoxy resin (EP) coatings containing QD with ratios of 0.05 wt%, 0.1 wt%, 0.2 wt%, and 0.5 wt% were successfully prepared subsequently. Surface analysis, electrochemical measurements, salt spray tests, and mechanical tensile tests were performed to characterize the prepared quantum dots and study the anti-corrosion behavior and mechanism of the prepared coatings. Results indicated that the prepared CuS and ZnS quantum dots have small sizes with values of 13.8 and 8.9 nm, respectively. Compared to the pure EP coating, QD-EP coatings have a higher mechanical strength and toughness which is conducive to improving the coatings’ corrosion resistance and service life. The impedance values of all the QD-EP coatings increase by more than three orders of magnitude in contrast to pure EP coating after 60 d of testing. Furthermore, the prepared QD-EP coatings possess a long-term anti-corrosion property.
