Wastewater pollution is a worldwide concern, and wastewater treatment is gaining growing global attention. Electro-Fenton is a promising method for the treatment of wastewater containing organic pollutants. This work offers an overview and bibliometric analysis of research on electro-Fenton treatment of wastewater. The literatures, consisting of 1898 documents from 2000 to 2021 collected from the Web of science database, were analyzed using bibliometric tools such as Bibliometrix package, CiteSpace, and VOSviewer. Document types, publication trends, subject categories, journals, institutions, countries, authors, keywords, and highly cited papers were analyzed. Research in this field has undergone three stages with the rapid development in the past 5 years. Environmental sciences (24.42%) is the leading Web of science category, and Engineering (48.37%) is the leading research area. China (38.46%) is the most productive country, followed by Spain (8.59%), Iran (8.11%), France (6.27%), and India (5.80%), while University of Barcelona (7.38%) is the most productive institute.

作者： Cai, Yutao Meng, Yuan Cheng, Yu Guan, Minghang Liu, Xiubo School of Materials Science and Engineering Central South University of Forestry and Technology Changsha410004 China Hunan Province Key Laboratory of Materials Surface & Interface Science and Technology Changsha410004 China

Boron Functionalized Cellulose-nanocrystal (BFC) was prepared by a facile and green esterification route. BFC had a high crystallinity of more than 80% and a needle-like morphology with a length of hundreds nm and a diameter of 10~20 nm, very similar to those of cellulose nanocrystal. The largest degree of substitution of hydroxyl by borate ester group was obtained for BFC under the optimum conditions of reaction time and temperature (5 h, 80 ℃). When used as a lubricant additive in castor oil, BFC-5-80 achieved a stable, homogeneous and monodisperse state and the tribological performances were evaluated by a reciprocating ball-on-plate tribometer. The friction coefficient and wear volume of castor oil with 2wt.% BFC-5-80 are 0.058 and 0.281×10-3 mm3 under certain conditions of load, frequency and testing time (6 N, 8 Hz, 2 hours), 23.7% and 59.2% lower than those of pure castor oil as well as 8.0% and 33.9% than those of castor oil with CNC. Based on the analysis results of worn surfaces and wear residues, the outstanding friction-reduction and anti-wear performances of BFC-5-80 can be explained by two facts that a complete film consisting of BFC-5-80 network and adsorbed castor oil molecules forms between the mating surface and a chemical transfer film composed of ferrum boride and iron oxides is also generated on the steel interface. © 2024, The Authors.

High Performance of Cellulose Nanocrystal Based Bicomponent Supramolecular Hydrogel Lubricants

SSRN

引用

SSRN 2024年

作者： Zhou, Yulong Meng, Yuan Cheng, Yu Guan, Minghang Liu, Xiubo School of Materials Science and Engineering Central South University of Forestry and Technology Changsha410000 China Hunan Province Key Laboratory of Materials Surface & Interface Science and Technology Changsha410000 China

Cellulose nanocrystal based bicomponent supramolecular hydrogel (CNC/x-DG/y) was prepared by a simple mixing method using CNC and diglycerol (DG) as gelators. Once deionized water is set at 1 mL, CNC/x-DG/y hydrogel becomes stronger with increasing CNC content (no less than 2.4 wt%), but weakened with enhancing DG content (0.1~1.3 mL). The gelling mechanism is attributed to multiple H-bonds between DG and CNC, which can self-assemble into a three-dimensional network to effectively trap water molecules. CNC/x-DG/y hydrogel shows many advantages for lubrication application, including reversible shear thinning behaviours, satisfactory viscoelasticity, excellent creep recovery performances, outstanding anti-rust property and much lower water volatilization rate, which exactly have improved the drawbacks of water-based lubricants. CNC/2.4-DG/0.1, a typical CNC/x-DG/y hydrogel, exhibits excellent tribological performances which are deeply dependent on the applied load and the reciprocating frequency. The friction coefficient and wear volume for CNC/2.4-DG/0.1 are 0.059 and 0.81×10-3 mm3, apparently lower than those for two reference lubricants. The high performance for reducing friction and wear of CNC/2.4-DG/0.1 can be ascribed to the synergistic mending effect of CNC nanoneedles and DG molecules and the dissipative effect caused by H-bonds between CNC nanoneedles and DG molecules. © 2024, The Authors.

Enzyme catalysis is characterized by high efficiency and selectivity;however, the natural enzymes are prone to inactivation once removed from their native environment. The immobilization of enzyme using solid-phase carriers presents an effective strategy to enhance the structural stability of natural enzymes. In this study, organophosphate hydrolase (OPH) was utilized as the organic component, while ferrous phosphate served as the inorganic component, leading to the synthesis of enzyme-inorganic hybrid nanoflower materials through biomimetic mineralization. After characterizing the microstructure and compositional characteristics of this composite material, the hydrolysis of para-nitrophenyl phosphate (PNPP) was employed as a probe reaction to determine the optimal temperature (30 °C) and the ideal pH value (9) for the immobilized enzyme. Due to the protective effect of the inorganic carrier, the immobilized enzyme exhibited significantly enhanced thermal stability, acid-base resistance, proteolytic resistance, organic solvent tolerance, and reusability compared to the free enzyme. In addition, the potential of this immobilized enzyme for stepwise degradation of toxic organophosphorus compounds by tandem hydrolysis reactions and advanced oxidation processes was further validated. This work provides a novel approach to further expand the application scope of multi-component cascade catalytic systems based on enzyme-inorganic hybrid nanoflowers. © 2025 Elsevier B.V.

Silicon-based materials are considered among the most promising anode materials for the next generation of lithium-ion batteries due to their abundant reserves, high theoretical capacity, and lower discharge potentials. However, the poor conductivity, significant volume expansion, and severe capacity fading of silicon hinder its commercial application. The synergistic use of silicon and graphite is an effective way to address these issues but faces problems such as persistent interface and structural stability challenges. This study employs sulfur-doped carbon derived from sulfonated polyacrylonitrile to encapsulate silicon, with graphite serving as the conductive medium. Through a combined wet and pyrolysis process, we synthesized Si@SPANdC/Gr composite materials with superior electrochemical performance. The 3gSi@SPANdC/Gr composite anode material, containing a medium silicon content (~19.1 wt%), demonstrated a reversible capacity of 628.8 mAh g-1 at a current density of 0.2 A g-1 over 200 cycles, with an initial coulombic efficiency of 71.28%. Even at a higher current density of 1 A g-1, it maintained a relatively high reversible capacity of 516.8 mAh g-1 after 400 cycles, indicating good cycle stability. This research provides a low-cost and novel solution for the commercial application of high-performance silicon-based lithium-ion batteries. © 2024, The Authors. All rights reserved.

The present study involves the in-situ preparation of a NiMoO4-C@NiFeMoSe composite electrocatalyst on a nickel foam (NF) substrate, achieved through the combined use of hydrothermal and electrodeposition techniques. After the hydrothermal process, the NF substrate was enveloped by a notably rugged composite structure composed of carbon sub-micron spheres uniformly dispersed and interlinked with NiMoO4 nanorods. To further enhance the electrocatalytic efficiency, a NiFeMo-based selenide was electrodeposited onto the surface of the NiMoO4-C/NF composite electrode. The NiMoO4-C@NiFeMoSe/NF composite electrode exhibited exceptional OER catalytic activity in a 1 M KOH solution, displaying an overpotential of merely 228 mV at a current density of 50 mA·cm-2 and a Tafel slope of 35.9 mV·dec-1, significantly lower than that of the blank NF. Moreover, for overall water splitting, the two-electrode NiMoO4-C@NiFeMoSe/NF||Pt-C/NF electrolyzer required a low potential of 1.48 V to achieve a current density of 10 mA·cm-2 and displayed exceptional long-term durability. © 2024, The Authors.
