The integration of selective oxidation of renewable biomass and its derivatives with hydrogen (H 2 ) production holds significant potential for simultaneously yielding value-added chemicals and “green H 2 ”, contributing to addressing sustainability challenges. The S-scheme charge transfer mechanism enhances charge separation by maintaining strong redox potentials at both ends, facilitating both oxidation and reduction reactions. Herein, we synthesize a visible-light-responsive, oxygen vacancy-rich In 2 O 3- x /tubular carbon nitride (IO OV /TCN) S-scheme heterojunction photocatalyst via electrostatic adherence for selective 5-hydroxymethylfurfural (HMF) oxidation to 2,5-diformylfuran (DFF) and 2,5-furandicarboxylic acid (FDCA), alongside H 2 production. Under anaerobic conditions and visible-light irradiation, the optimal IO OV /TCN-10 catalyst achieves an HMF conversion of 94.8% with a selectivity of 53.6% for DFF and FDCA, and a H 2 yield of 754.05 μmol g −1 in 3 h. The significantly improved photocatalytic activity results from enhanced visible-light absorption, reduced carrier recombination, and abundant catalytic active sites due to the synergistic effect of surface oxygen vacancies, the hollow nanotube-based architecture, and the S-scheme charge transfer mechanism. This work highlights the great potentials of S-scheme heterojunctions in biomass conversion for sustainable energy use and chemical production.

Iron-nitrogen-carbon (Fe-N-C) single-atom materials have emerged as the most promising catalysts for the oxygen reduction reaction (ORR), which yet suffers from inadequate stability arising from the attack of ·OH and HO 2 · radicals generated by H 2 O 2 . In this study, density functional theory (DFT) calculations reveal that the presence of peripheral S atoms can regulate the electronic structure of the Fe center and suppress the formation of H 2 O 2 to enhance the catalyst's durability. Thereafter, atomic Fe-N 4 with peripheral S doping is intricately engineered in defect-rich porous carbon nanoshells (Fe-NS-C) through an adsorption-pyrolysis method. The incorporation of S not only optimizes the coordination microenvironment of Fe-N 4 but also induces a larger specific surface area and richer defects. The Fe-NS-C catalyst displays remarkable ORR performance, featuring a half-wave potential (E 1/2 ) of 0.90 V. Its low H 2 O 2 yield (below 1.1 %) and excellent stability (10 mV day in E 1/2 after 10,000 cycles) further underscore the superiority of Fe-NS-C. When employed as the cathode for Zn-air battery, Fe-NS-C achieves an impressive peak power density of 230.1 mW cm −2 and stable charge/discharge potentials over an extended duration of 150 h. This study presents an effective strategy for engineering efficient and durable single-atom electrocatalysts for ORR and Zn-air batteries.

In this work, by using a flexible tricarboxylate ligand 5-(4-carboxybenzyloxy) isophthalic acid (H 3 L), a novel pillar-layered Mn–organic framework, namely, [(CH 3 CH 2 ) 2 NH 2 ][Mn 3 (HL)L(A C ) 2 ] ( SQNU-23 , SQNU = Shangqiu Normal University), was synthesized by using a DEF/HAc solvent system. In SQNU-23 , each S-shaped Mn-O chain is interconnected by two bridging modes of organic ligand to form a 3D pillar-layered framework with 1D rectangular channels. The solid-state fluorescence of SQNU-23 exhibits a significant red shift of about 140 nm compared to that of organic ligand. Moreover, SQNU-23 as a luminescent thermometer exhibits good linear dependence in the wide temperature range (100 to 300 K).

The soil near tailings areas is relatively barren and contaminated by multi-metal(loid)s, seriously threatening the safety of crop production. Here, biochar and nano-hydroxyapatite (nHAP) were combined to improve the sterilized and unsterilized polymetallic contaminated soil, and soil incubation and soybean pot experiments were designed. Results showed that biochar and nHAP not only increased soil C, N, and P but also effectively reduced multi-metal bioavailability, wherein the combined application of the two amendments had the best effect on metal immobilization. The synergistic effect of the two amendments decreased the acid-soluble contents of Co, Cu, Fe, and Pb in rhizosphere soils up to 86.75%, 80.69%, 89.09%, and 96.70%, respectively. The ameliorant reduced the accumulation of metal(loid)s in soybean plants, and rhizosphere microorganisms inhibited the migration of soil metals to plants. Additionally, biochar and nHAP regulated the rhizosphere soil microbial community. The rhizosphere soil of the sterilization group tended to prioritize the restoration of the original dominant bacteria. As, Pb, Fe, Urease, OM, TN, and TP were the critical environmental variables affecting rhizosphere soil bacterial communities. Therefore, combining biochar and nHAP is an environmentally friendly strategy to reduce polymetallic mobility in tailings soil and crops and improve soil microbial community structure.

With the rapid development of large-scale clean energy, lithium-sulfur (Li-S) batteries are considered to be one of the most promising energy storage devices. In this manuscript, the polymetallic hetero-nanocrystal of iron nickel@cobalt nitride encapsulating into boron carbonitride nanotubes (Fe 0.64 Ni 0.36 @Co 5.47 N@BCN) was designed and optimized for use as a modified material for commercial polypropylene (PP) separators. The prepared Fe 0.64 Ni 0.36 @Co 5.47 N@BCN-12 hybrid material presents strong chemisorption and catalytic conversion capabilities, which endows the Fe 0.64 Ni 0.36 @Co 5.47 N@BCN-12//PP separator with enhanced polysulfide shuttling inhibition. The assembled Li-S cells with Fe 0.64 Ni 0.36 @Co 5.47 N@BCN-12//PP separators have minimized charge transfer resistance and faster redox kinetics. Additionally, cells with Fe 0.64 Ni 0.36 @Co 5.47 N@BCN-12//PP separator provide high reversible capacity of 674 mAh/g for 400 cycles at 0.5C and excellent cyclability for 1000 cycles at 2C with a low decay rate of 0.05 % per cycle. Therefore, this study provides a feasible functionalization route for improving the electrochemical performance of Li-S batteries through separator modification.

Scope Allicin, a product of enzymatic reaction when garlic is injured, plays an important role in maintaining glucose homeostasis in mammals. However, the effect of allicin on glucose homeostasis in the state of insulin resistance remains to be elucidated. This study investigates the effect of allicin on glucose metabolism using different muscle fibers in a chicken model. Methods and results Day-old male Arbor Acres broilers are randomly divided into three groups and fed a basal diet supplemented with 0, 150, or 300 mg kg −1 allicin for 42 days. Results show that allicin improves the zootechnical performance of broilers at the finishing stage. The glucose loading test (2 g kg −1 body mass) indicates the regulatory role of allicin on glucose homeostasis. In vitro results demonstrate allicin increases glutathione (GSH) level and the expression of cystathionine γ lyase (CSE), leading to endogenous hydrogen sulfide (H 2 S) production in M. pectoralis major (PM) muscle-derived myotubes. Allicin stimulates adenosine monophosphate-activated protein kinase (AMPK) S-sulfhydration and AMPK phosphorylation to promote glucose uptake, which is suppressed in the presence of d , l -propargylglycine (PAG, a CSE inhibitor). Conclusion This study demonstrates that allicin induces AMPK S-sulfhydration and AMPK phosphorylation to promote glucose uptake via the CSE/H 2 S system in a muscle fiber-dependent manner.

Optically active helical poly[( R or S )-3-(9-alkylfluoren-9-yl)propene oxide]s (poly-AFPOs) were used to induce the enantioselective addition of methyllithium to aldehydes. The addition of methyllithium to 4-methoxybenzaldehyde gave the highest enantioselectivity (88% ee) under the inducement of poly-AFPOs. Poly-AFPOs could be recovered simply by pouring the reaction mixture into methanol in the end of the reaction and separating the precipitated polymer via filtration. The recovered poly-AFPOs could be reused for many times to induce the enantioselective addition of methyllithium to aldehyde without losing their enantioselective inducement ability. The investigation of the optical rotation and the MALDI-ToF MS confirmed that, in the enantioselective addition induced by poly-AFPOs, the lithium cation was embedded in the hole of the helical column of poly-AFPOs, leaving the negative methyl ion outside the one-handed helical column. The methyl anion abutted tightly against the helical polymer and acquired a chiral environment. It was this helically chiral environment that resulted in the enantioselective inducement of the addition reaction.

Organic pollutants in industrial and agricultural wastewater can be dangerous to both human health and the environment. Therefore, it is important to develop methods for continuous catalytic reduction of these pollutants under dark conditions as sunlight has geographical and temporal limitations due to different regions, weather conditions, and Earth's rotation . This could have significant implications for practical wastewater treatment . In this study, we successfully synthesized bimetallic vanadium bismuth oxy-sulfo bromide (labeled as VBiOSBr) catalysts using a simple precipitation method by doping V/S into BiOBr to from (Bi,V)(S,O)Br. The morphology, structure, optical absorption properties, electron-hole recombination rate, and reduction performance of the catalysts were examined in detail. The catalyst displayed a tetragonal phase with an energy band gap and specific surface area of approximately 1.93 eV and 22.1 m 2 /g, respectively. The 1-VBiOSBr catalyst prepared with n (V): n (Bi): n (KBr): n (C 2 H 5 NS) = 1: 1: 1: 1 had the best catalytic activity . Within just 14 min, this catalyst removed 98.7% and 96.96% of 4-NP and Cr 6+ , respectively. The VBiOSBr catalyst remained stable and efficient even after the seventh run, still achieving a removal rate of 94.7%. The study proposed a possible mechanism for 4-NP and Cr 6+ reduction activity. The catalyst's simple manufacturing process and its ability to reduce pollutants under dark conditions make it a promising system for practical application in the continuous removal of organic pollutants. So, the VBiOSBr bimetallic catalyst has great potential as a candidate for wastewater treatment technologies.

Multivariate transition metal sulfides and porous nanosheet architectures hold promising potential for applications for the energy-related application. Nevertheless, the addition of polymer binders and conductive agents can adversely affect their electrochemical performance. In this work, we present self-assembled Ni-Co sulfide nanosheet arrays growing on foamed Ni (Ni-Co-S@NF). Ni-Co-S@NF electrode materials are synthesized through the complete sulfidation of interconnected ultrathin nanosheets derived from NiCo layered double hydroxides. The highly conductive nickel foam facilitates electron transfer while the 3D network structure promotes electrolyte diffusion and penetration. Hence, porous Ni-Co-S@NF materials presents the excellent specific capacitance as 1286.6C g −1 in 1 A g −1 and retained 70 % of its original capacity over 5000 charge–discharge cycles. Furthermore, we assemble an asymmetric supercapacitor used active carbon as negative-electrode material and Ni-Co-S@NF as positive-electrode material. This device delivers the specific energy is 74.0 Wh kg −1 and specific power of 850.0 W kg −1 .

Developing S-scheme photocatalysts with excellent catalytic activity and convenient retrieval is highly desirable for wastewater purification. Herein, a novel S-scheme MIL-101(Fe)/WO 3 heterojunction on carbon cloth is successfully synthesized via a facile solvothermal approach. The optimized MIL-101(Fe)/WO 3 composite (MWC-1.5) has been found to be highly effective in activating peroxymonosulfate (PMS) and then degrading tetracycline hydrochloride (TC-HCl) with a 100% degradation rate when exposed to visible light (Vis) within a period of 20 min. Such MWC-1.5/PMS/Light system also shows stable cycling performance and good recyclability. The remarkable photocatalytic degradation performance is mainly attributed to the powerful intrinsic electric field that accelerates the separation of photogenerated charge carriers via the S-scheme charge transfer. Radical quenching experiments and electron paramagnetic resonance (EPR) results suggest that SO 4 – and OH are the major oxidizing substances in the photocatalytic processes. Three potential degradation pathways are deduced based on an in-depth analysis of the degradation intermediates and the degradation mechanism is also elucidated through a rational combination of the experimental studies and theoretical calculations. This novel hybrid photocatalyst system has been shown to be a promising strategy for environmental remediation, while also suggesting a feasible approach for the development of photocatalysts with both remarkable activity and stability.

The photocatalytic reduction of CO 2 and H 2 O to form formic acid (HCOOH) holds promise for meeting the carbon–neutral target. However, the reduced efficiency of carrier separation and the material’s vulnerability to photo-corrosion significantly impede its practical application. Herein, a 0D/1D Cu 2 O/W 18 O 49 S-scheme heterostructure is prepared by in situ growing Cu 2 O nanocrystals on W 18 O 49 ultrathin nanorods via the wet chemistry method. In situ irradiation X-ray photoelectron spectroscopy characterization uncovered the formation of a stable internal electric field (IEF) at the heterojunction interface between W 18 O 49 and Cu 2 O, which facilitates the separation of photon-generated carriers through an effective interfacial S-scheme transmission mechanism. Small-sized Cu 2 O (5–10 nm) anchored on the ultrathin W 18 O 49 nanorods exposes abundant active sites and enhances carrier separation while inducing electrons generated from W 18 O 49 to consume the holes in Cu 2 O, thus preventing the oxidation of Cu 2 O. The W 18 O 49 /Cu 2 O S-scheme heterostructure with the optimized composite ratio (40 % Cu:W) exhibited excellent performance in HCOOH production (56.42 μmol g −1 h −1 , 23.2-fold enhancement compared to pristine Cu 2 O) and 100 % selectivity for CO 2 photoreduction in water without any sacrificial reagents. This work provides a rational method for improving the stability of the catalyst and regulating charge carrier migration for highly selective CO 2 photoreduction in water.

Bismuth oxyhalide (BiOI) has been used for photoelectrochemical catalysis in the field of catalytic hydrogen evolution, but it in a single-phase form has hardly been reported for photocatalytic hydrogen evolution reaction (PHER). Herein, we designed a W/S co-doped BiOI-based superhydrophilic catalyst with oxygen vacancy-rich defects and heterovalent valence states for efficient PHER under visible light. The W/S doping in BiOI not only adjusts the energy band structure and expands the visible light response range, but also transforms its hydrophobicity into superhydrophilicity, with which the gas bubble amount can be reduced and PHER activity enhanced. The introduction of sulfur regulates the content of oxygen vacancies which enhance the active surface sites for capturing water molecules and activating the H-O-H bond. The added tungsten exists in different valence states of W 6+ and W 5+ which is beneficial for electron hopping and PHER activity. The W/S-BiOI-3 with the suitable W/S doping content exhibits the highest visible-light PHER rate of 9.46 mmol·g −1 ·h −1 , with an apparent quantum efficiency (AQE) of 9.7 % at 420 nm. W/S-BiOI-3 shows excellent PHER activity, stability, and durability, which provides a feasible scheme for other bismuth-based halogen oxides to be used in PHER.
