Abstract ：
The low light absorption capacity, fast recombination of photogenerated carriers and slow H+ reduction kinetics of carbon nitride severely limit its application in photocatalytic research. What's more, the challenge remains to efficiently utilise photogenerated electrons. In this work, sulfur (S) self-doped carbon nitride (SCN) was formed by thermal polymerisation, and the introduction of S stimulated the electron delocalisation of the active site and optimised the absorption of visible light by the carbon nitride. The introduction of defects and cyano (-C N) groups optimises the surface atomic and electronic structure of SCN, enhances photogenerated electron trapping and greatly suppresses charge recombination. The n-pi* electron jump of the lone pair of electrons at the defect site gives rise to a new absorption band that broadens the response to visible light. The H-2 evolution rate of SCNV under visible light reached 3437 mu mol g(-1) h(-1), which was about 3.0 times higher than that of SCN (1148 mu mol g(-1) h(-1)). Density Functional Theory (DFT) calculations further show that the introduction of defects and -C N lowers the energy barrier of *H, enhances carrier separation, and forms an electron-rich structure, which effectively promotes the utilisation of photogenerated electrons and photocatalytic H2 evolution efficiency.

Abstract ：
Highly permeable polyamide (PA) membranes with precise ion selection can be used for many energy-efficient chemical separations but are limited by membrane inefficiencies. Herein, polyphenol-mediated ZIF-8 nano- particles with hydroxyl-rich hollow structure were synthesized by tannic acid tailored regulation. PA-based membranes with fast penetration, high retention, and precise Cl-/SO42- selection were then synthesized through spatially and temporally controlling interfacial polymerization with modified ZIF-8 nanoparticles (tZIF8) as aqueous phase additives or as interlayers. The effects of the embedding position of tZIF-8 on the structure, morphology, physicochemical properties, and performance of PA-based membranes were explored through a sequence of characterization techniques. The results revealed that the PA-based membrane with tZIF-8 embedded in the PA layer could achieve a high water permeance of 24.8 L m- 2 h- 1 bar- 1 with a high retention of 99.4 % Na2SO4 and a Cl-/SO42- selectivity of 141, which was superior to most state-of-the-art PA-based membranes. Comparatively, the Cl-/SO42- selection of the PA-based membrane with tZIF-8 embedded between the PA layer and the substrate was 136, while the water permeance was slightly enhanced to 28.2 L m- 2 h- 1 bar- 1 . Excitingly, the resulting membranes all exhibit superior antifouling properties and stability. Our facile strategy for tuning membrane microstructures provides new ideals into the development of highly permeable and excellently selective PA-based membranes for precise ion sieving.

Abstract ：
Flexible thermal insulation membrane plays a key role in outdoor wear of human body and thermal management of electronic products. This study used electrospinning to prepare thermal insulation hollow silica/polytetrafluoroethylene (HSi/PTFE) fiber membranes. HSi were prepared using tetraethylorthosilicate as the silicon source and hydrothermal carbon spheres as templates. A spinning solution of PTFE containing the HSi was used to prepare fiber membranes. The heat transfer resistance of the fiber is improved by embedding HSi into the PTFE fiber, resulting to improved heat insulation capability of the fiber membrane. The influence of HSi content on the thermal insulation performance of PTFE fiber membrane was studied. When the HSi content was 5 %, the fiber membrane showed the lowest thermal conductivity (0.0197 W/(m·K)), which was not only lower than most fiber thermal insulation materials, but also had excellent tensile properties (tensile deformation capacity of 168 %), which was convenient for practical application. In addition, this kind of fiber membrane also has high hydrophobicity (water contact angle of 147°), effectively reducing the influence of moisture on thermal insulation performance.

Abstract ：
Particulate matter (PM) pollution causes critical harm to human health and global environment. However, the protective respirators attain high-performance filtration of the most permeable PM0.3 by tight stacking of fibers and seriously compromising their wearing comfort. Herein, a fluffy sandwich-structured membrane (SSM) composed of bimodal fibrous layers and bead-on-string fibrous layer is designed to endow the air filter with both high-performance filtration and superior thermal-wet comfort. Based on the electrospinning technique, the bimodal fibers made of nano-/submicron-fibers (about 46 nm and 155 nm) are formed by inducing the jet splitting while the bead-on-string fibers consisting of submicron-fibers (≈ 120 nm) and micro-beads (≈ 3.37 μm) are prepared through manipulating the Rayleigh instability of jets. Due to the structural design of small pores and low packing density, the SSM exhibits excellent PM0.3 removal of 99.8%, low filtration resistance of 65 Pa, and high quality factor of 0.097 Pa-1. It also shows long-term filtration stability and durability under high humidity conditions. Moreover, the SSM simultaneously possesses superior thermal-wet comfort of heat dissipation, air permeability of 164 mm·s-1, and water vapor transmission of 7.6 kg·m-2·d-1. This work may offer a novel insight for exploiting high-performance and comfortable personal protective materials. © 2024 Elsevier B.V.

Abstract ：
The membrane fouling derived from the accumulated dust pollutants and highly viscous oily particles causes irreversible damage to the filtration performance of air filters and results in a significant reduction in their service life. However, it is still challenging to construct high-efficiency and antifouling air filtration membranes with recyclable regeneration. Herein, the fluorine-free amphiphobic micro/nanofiber composite membrane was controllably constructed by integrating click chemistry reaction and electrospinning technique. Low-surface-energy fibers were constructed by a thiol-ene click chemical reaction between mercaptosilane and vinyl groups of polystyrene-butadiene-styrene (SBS), combined with hydroxyl-terminated poly(dimethylsiloxane) during the electrospinning process. The functional air filter is then prepared by the two-layer composite strategy. Because of the advantages of liquid-like fibrous surface and micro/nanofibrous porous structure, SBS/PAN composite membrane simultaneously shows superior antifouling performances of pollutants and filtration efficiency of over 97% PM0.3 removal. More importantly, the antifouling fibrous membrane still presents a stable and efficient filtration efficiency after multiple washes. Its service life in dust filtration environments is approximately 1.7 times longer than that of the substrate membrane. This work may provide a significant reference for the design of antifouling fiber membranes and high-efficiency air filters with long life spans and reusability. © 2024 American Chemical Society.

Abstract ：
Plastics, accumulating globally as microplastics in living organisms, significantly contribute to environmental issues. Current materials like polylactic acid and commercial paper face limitations due to inadequate heat and water resistance, resulting in various practical inconveniences. This study reports a high-strength, water-resistant, recyclable, and naturally degradable pure cellulose food packaging material, which is crafted from bacterial cellulose (BC) and ethyl cellulose (EC) by a straightforward filtration and scratch coating process. The use of the EC ethanol solution eliminates the need for additional binders. Remarkably, the EC-BC pure cellulose material exhibits excellent mechanical properties (tensile strength of 195.3 ± 23.2 MPa), a stability in liquid environments (136.9 ± 24.2 MPa mechanical strength after 30 minutes of immersion in water), recyclability, natural degradability, cost-effectiveness, and non-toxicity. These attributes position binder-free hybrid designs, based on cellulose structures, as a promising solution to address environmental challenges arising from the extensive use of single-use plastics. © 2024 The Author(s)

Abstract ：
The frequent occurrence of oil spills not only results in the waste of petroleum resources, but also poses a serious threat to the marine ecological environment. Considering the large amount of crude oils with high viscosity, it is urgent to develop a sorbent capable of efficiently reducing the viscosity for the cleanup of oil spills. Inspired by the "lotus effect" and "poikilotherm which utilize the solar energy for thermoregulation", the low surface energy material polydimethylsiloxane (PDMS) and polypyrrole (PPy) were loaded over the island nonwoven fabric to fabricate a novel crude oil sorbent material. The nonwoven fabric achieved an efficient photothermal conversion. Wherein, the fluorine-free PDMS was used to hydrophobically modify the nonwoven fabric, endowing it with excellent oil-water separation performance, with a separation efficiency of up to 95%. After 10 cycles, the separation efficiency of PPy/PDMS modified nonwoven fabric (PPy/PDMS@NF) was still above 90%, demonstrating superior recyclability. In addition, the PPy/PDMS@NF possessed the self-cleaning capabilities. Under light conditions, the PPy/PDMS@NF was rapidly heated up, reducing the viscosity of crude oil and enabling the effective recovery of oil spills. Under one sun illumination (1.0 kWm-2), the surface temperature of the PPy/PDMS@NF reached 60.7 degrees C, and its sorption capacity for high-viscosity crude oil reached 7 gcrude oilgsorbent-1. Thanks to its environmental friendliness and excellent sorption capacity, this work provides a new option for dealing with the high-viscosity marine oil spills.

Abstract ：
Polyphenylene sulfide (PPS), commonly used as a core material for high -temperature flue gas treatment, exhibits elevated viscosity when processed even at temperature exceeding 280 degrees C. In this study, a novel high-flowability PPS -based composite was fabricated through the incorporation of graphitic carbon nitride (g-C3N4) via a wellestablished melt extrusion procedure. The enhancement of flowability in PPS was verified, and the material's texture structures and fundamental properties of composites with varying contents were determined. The composites exhibit well -dispersed g-C3N4, a significant reduction in shear viscosity (>10 %), a notable increase in melt index (>30 %), improved crystallinity, and comparable or superior performance compared to pure PPS. When the g-C(3)N(4 )was introduced into the PPS matrix, a phase -separated composite structure was formed. This structure reduces the entanglement degree between the PPS molecular chains and provides more space for freemovement of the PPS chains, and thus the improvement in flowability for the composites can be clearly demonstrated. Therefore, g-C(3)N(4 )can be used as a novel flow modifier to enhance the flowability and stability of PPS resin without compromising its fundamental properties, which offers significant prospects for improving productivity, optimizing energy usage, and managing costs for PPS -based products.

Abstract ：
Metal-doping is a common strategy for establishing active sites on photocatalyst, but appropriately exposing them for maximized atomic utilization remains a great challenge in photocatalytic research. Herein, we propose a metal organic framework (MOF)-assisted approach to synthesis copper-modified titania (Cu-TiO2/Cu) photocatalyst with homogenously distributed and highly accessible active sites in its matrix. Significantly, an MOF precursor, namely NH2-MIL-125, with co-chelation of titania (Ti) and copper (Cu) was subjected to mild calcination, subsequently results in Cu-modified TiO2 with highly accessible channels to its inner surface. These channels provide not only a large reactive surface (>400 m(2) g(-1)); they also enable facile modifying route for the pre-deposited Cu in prior to photoreaction. Specifically, NH3 treatment was applied to partially reduce deposited Cu ions (Cu+ and Cu2+) into Cu nanoparticles, where their interplays realize improved optical properties and charge separation during photoreactions. Furthermore, the NH3-induced Cu nanoparticles could also serve as the adsorptive site for H+, thereby enabling 5629 mu mol h(-1) g(-1) H-2 generation over the optimum photocatalyst of Cu-20/TiO2/Cu-500. Such performance is associated to 35.44 and 1.71-fold improvements compared to pure TiO2 (Cu-0/TiO2) and untreated Cu-ion modified TiO2 (Cu-20/TiO2), respectively. This work offers a new synthetic strategy for obtaining photocatalyst with evenly distributed and highly accessible active sites, thus improving the commensurability of photocatalytic H-2 generation from the industrial perspective.
