Due to their high reactivity and theoretical capacity, chalcogen elements have been favored and applied in many battery studies. However, the high surface charge density and high solubility of these elements as electrode materials have hindered their deeper exploration due to the shuttle effect. In this article, organic structural triphenylphosphine is used as a molecular main chain structure, and chalcogen elements O, S, and Se are introduced to combine with P as active sites. This approach not only takes advantage of the beneficial effects of the aromatic ring on the physical and chemical properties of the chalcogen element but also allows for the optimization of its advantages. By utilizing Triphenylphosphine selenide (TP-Se) as the cathode material in aluminum-ion batteries(AIBs), a high-performance Al-organic battery was fabricated, which exhibited a high initial capacity of 180.6 mAh g −1 and stable cycling for up to 1000 cycles. Based on density functional theory (DFT) calculations, TP-Se exhibits a smaller energy gap, which renders it favorable for chemical reactions. Moreover, the calculated results suggest that TP-Se tends to undergo redox reactions with AlCl 2 + . The molecular structure of triphenylphosphine and its combination with Se offers an enticing pathway for designing cathode materials in aluminum-organic batteries.

Magnesium–sulfur (Mg–S) batteries have received extensive attention due to the high theoretical energy density, low cost, high safety, and environmental friendliness. In this work, sulfurized pyrolyzed polyacrylonitrile (S@pPAN) composite is used as a cathode material of Mg–S batteries, and a comparative study on the effects of different binders on the electrochemical performance is reported for the first time. The selected binders are commercial organic-soluble poly(vinylidene fluoride) (PVDF) and water-soluble poly(ethylene oxide) (PEO), sodium polyacrylate (PAAS), locust bean gum (LBG), guar gum (GG), carboxymethyl cellulose (SCMC), and β-cyclodextrin (β-CD). The binders significantly affect the physical properties of S@pPAN electrodes and thus the electrochemical performance of the batteries. Compared to the traditional PVDF binder and other water-soluble binders, the S@pPAN electrode with an amorphous PAAS binder has better cycle stability and rate capability. The three-dimensional (3D) network formed from PAAS cross-linking improves the cohesion among the electrode constituents, and the adhesion between the electrode laminate and the current collector maintains the uniformity of electrode surface after cycling. The present work demonstrates the feasibility of using green aqueous binders to enhance the electrochemical performance of Mg–S batteries.

Antimony (Sb) is a competitive candidate for lithium ion batteries (LIBs) as anode material because of its high theoretical discharge capacity (660 mAh/g). However, it remains a challenge caused by the volume change in the process of charge and discharge, which would damage the Sb anode that lead to poor rate performance and low cycle stability. Herein, we report the synthesis of Sb@S–N–C nanocomposite as the anode material to solve the problem. First, SbSI nanowires with diameter of ∼10 nm were synthesized. Then the SbSI nanowires were coated with polypyrrole (PPy) to form SbSI@PPy core-shell nanowires. By thermal reduction of SbSI@PPy, Sb@S–N–C nanocomposite was formed. Using the Sb@S–N–C nanocomposite as the anode material, a capacity of 536 mAh/g was obtained in 100 cycles at 0.5 A/g. Excitingly, it also exhibited superior reversible and long-cycle non-decay stability with the capacity of 342 mAh/g in 2000 cycles at a high current density of 1A/g.

Although reasonably specified and adjustable preparation of nanostructures with specific morphologies, ordered chemical compositions and electronic structures involving advanced energy chemistries is an important research area, high-efficiency, stable, and low-cost electrocatalysts for water splitting are greatly desirable and challenging. In this study, partially delocalized Co–S–Se ultra-thin nanosheets are obtained via a liquid–liquid interface-mediated strategy at an oil–water interface. These Co–S–Se ultra-thin nanosheets exhibit different-sized lamellar structures and have an average thickness of 0.83 nm. The ternary ultra-thin Co0.45S0.38Se0.17 nanosheets demonstrate excellent performance for the OER, accompanied by an overpotential of 290 mV (1.52 V vs. RHE) at 10 mA cm−2, and a Tafel slope of 74.5 mV dec−1. In the meantime, the catalyst recombined with a stoichiometry NiOx catalyst to form a composite interface, which also exhibited a good OER performance, with an overpotential of 260 mV at 10 mA cm−2 and a smaller Tafel slope of 53.9 mV dec−1. The nanosheets can rearrange the electronic density near the metal catalytic centers and increase the electron transfer. DFT calculations indicate that the partially delocalized charges can improve electrocatalytic performances, demonstrating modulated electroreduction properties. Due to the special atomic and electronic structure of the ternary transition metal alloy chalcogenide, the compound has great potential for energy storage, which will help in the rational design and synthesis of high-efficiency electrocatalysts.

The state-of-the-art copper indium gallium selenide Cu(In,Ga)Se2 (CIGS) thin-film solar cells are fabricated based on vacuum methods and use cadmium sulfide as the buffer layer. Considering the cost-effective production and environmental safety, fabrication of a CIGS absorber via the solution process and using a cadmium-free buffer layer is desirable. Here, we report engineering of a chemical-bath-deposited zinc sulfoxide Zn(S,O) buffer layer for solution-processed CIGS solar cells. Our results show that optimization of the deposition time and annealing process of the Zn(S,O) film to avoid cracking is critical to obtain a dense and uniform Zn(S,O) buffer layer. Benefited from the large band gap of Zn(S,O) and light-soaking-induced device performance improvement, a champion CIGS solar cell with a power conversion efficiency of 12.0% (without antireflection coating) has been achieved. This is the first time that the Zn(S,O) buffer layer has been applied to a solution-processed CIGS absorber and achieves highly efficient CIGS solar cells. The effect of light-soaking on the heterojunction property and the stability of device performance are discussed.

Lithium sulfur (Li–S) battery is considered as one of the most viable candidates for next-generation rechargeable batteries. However, the development of Li–S battery is severely hindered by the stubborn “shuttle” issue that arises from the dissolution of the intermediate polysulfides. Herein, a new kind of organosulfur polymer composite is designed as cathode material for Li–S batteries. Via a facile two-step heating method, the ring opening S is copolymerized with triallyl isocyanurate. The resulting S-triallyl isocyanurate organosulfur polymer composite (STI) demonstrates a unique two-phase structure: ultrafine monoclinic S particles embedded in the organosulfur polymer matrix, which enables a S content as high as 90 wt%. The STI cathode delivers a high initial reversible capacity of 904 mA h g −1 at 0.5 C, and an ultraslow capacity decay rate of 0.017% over 350 cycles at 1 C. The work offers new insights into the design of S-rich copolymer composite cathode for highly-stable Li–S batteries.

High energy density lithium-sulfur (Li-S) batteries have been extensively investigated in recent years due to the urgent demands for advanced energy storage systems . Among various sulfur cathodes reported in past decades, sulfurized pyrolyzed poly (acrylonitrile) (S@pPAN) cathode displayed several superiorities on electrochemical behaviors. However, further scale-up practical application of Li-S battery with S@pPAN cathode has been plagued by high-loading sulfur electrode preparation. Herein, a network binder system (i.e., guar gum and poly(acrylic acid)) is constructed through binding effect between substantial functional groups. The network binder ensures a simple blade-cast method for high-loading S@pPAN cathode up to 17.5 mg cm -2 on planar aluminum-based current collector. The optimization of dense sulfur electrode after rolling pressure reached a compacted density close to 1.15 g cm -3 and demonstrated a high areal capacity of 6 mAh cm -2 after 120 cycles. Benefiting from the simple method to prepare dense and high-loading S@pPAN cathode, the correlation between areal specific capacity with rolling pressure applied on electrodes was carefully analyzed. This study sheds light on the key issues of sulfur electrode preparation for high energy density lithium sulfur batteries .

The intelligent design of catalytic materials with unique architectures has a significant impact on regulating the polysulfides (LiPSs) conversion and boosting the performance of Li − S batteries. Here, starting from 2D catalytic MoS 2 nanosheets and combined with the first-principle calculations, the covalent heterojunction and S vacancy are simultaneously developed in MoS 2 to regulate the electronic structure and improve the LiPSs conversion kinetics. The S vacancy and heterojunction (MoS 2-x -Co 9 S 8-y ) engineering can significantly improve the electrical conductivity of MoS 2 by incorporating shallow donor levels into the MoS 2 . Moreover, the incorporation of Co 9 S 8-y greatly improves the chemisorption ability of heterostructure towards LiPSs. The LiPSs are preferentially adsorbed at the catalytic Mo-S-Co heterojunction, where both Li + and e - are easy to access. The coupled fast Li + /e - transportation of MoS 2-x -Co 9 S 8-y enables direct and fast LiPSs “adsorption-conversion” at the catalytic Mo-S-Co heterojunction with enhanced bidirectional catalytic properties. Due to the ingenious co-engineering of S vacancy and heterointerface, the Li − S cell with MoS 2-x -Co 9 S 8-y /rGO interlayer delivers high sulfur utilization (1382.5 mAh/g at 0.1C), excellent rate capability (710.2 mAh/g at 3C), and long cycle life over 600 cycles (0.06 % capacity decay per cycle). This work demonstrates the great potential of anion deficiency and heterojunction co-construction for high-performance Li − S batteries.

Designing highly efficient photocatalyst for the valorization of CO 2 is an ideal strategy to reduce greenhouse gas emissions and utilize solar energy. In this study, a S-scheme heterojunction photocatalyst is fabricated by solvothermal impregnation of ZnO on W 18 O 49 for photocatalytic CO 2 N -formylation of aniline. The localized surface plasmon resonance effect of W 18 O 49 improves the absorption capacity for long-wave light significantly, and the hot electrons generated in W 18 O 49 with a high energy can migrate to the conduction band of ZnO and thus enhance the photocatalytic reduction ability. Meanwhile, the S-scheme heterojunction facilitates the separation of photoinduced charge carriers and preserves the redox ability of W 18 O 49 /ZnO composite photocatalyst. The conversion of aniline reaches 99.1% after 5 h reaction under visible light irradiation at room temperature with an N -formylaniline selectivity of 100%. A possible photocatalytic reaction mechanism is proposed. This study paves a promising way for the design of highly efficient photocatalyst and the sustainable utilization of CO 2 .

The commercialization of Li-S batteries is constrained by the unstable interface, severe shuttle of polysulfides, and sluggish kinetic conversion reactions. Electrolyte regulation is a straightforward and efficient way to tackle those mentioned issues. Herein, a multifunctional electrolyte additive of 2,5-Dimercapto-1,3,4-thiadiazole (DMTD) is introduced in the ether-based electrolyte, which can be lithiated into Li 2 -DMTD when contacted with the Li or Li 2 S during the discharge process. The generated Li 2 -DMTD can operate as a highly ionic-conducting protective coating on the Li surface, inhibiting the formation of Li dendrites, and increasing interface stability. Then, it is reversibly oligomerized with Li 2 S, forming two organosulfur oligomers during the ensuing electrochemical process. Such a modified reaction routine can reduce the shuttle effect and speed up the reaction kinetics of Li 2 S at the cathode, preventing cathode passivation and boosting active material utilization. As a result, The Li||Li symmetric cells with DMTD exhibit about 5-fold cycle life than the reference cell under 5 mA cm −2 current density. Meanwhile, the initial charge voltage of Li||Li 2 S battery is greatly decreased from 3.7 V to 3.0 V with DMTD, and the assembled Li-S cell shows an improved capacity retention from 45.7 % to 81.2 % after 320 cycles. Therefore, this work successfully tackled the critical issues by designing functional organosulfur electrolyte additives in LSBs, which provides theoretical guidance for the electrolyte design in LSBs.

It is shown that replacing non-noble metals with noble metals in photocatalytic water splitting is pivotal for increased and sustained hydrogen production. However, the challenge persists in designing and developing a cost-effective, highly active catalyst with effective carrier separation and providing sufficient H + reduction sites to enhance photocatalytic H 2 evolution efficiency. Herein, a series of S-scheme Cu 2 ZnSnS 4 /g-C 3 N 4 (CZTS/CN) heterojunction composites were prepared via the hydrothermal method, followed by comprehensive characterizations for in-depth investigation. The TEM image exhibits a clear interface, showing the heterojunction formation between CZTS and CN nanosheets. The results show that incorporating CZTS cocatalyst significantly improves CN photocatalytic hydrogen evolution reaction (HER) and its performance is notably influenced by CZTS to CN mass ratio. Among CZTS/CN heterojunction composites, the 5% CZTS/CN heterojunction composite exhibited a significantly improved HER of 243.64 μmol g −1 h −1 , which is 29.4 and 7.08 folds superior as compared to CN (8.29 μmol g −1 h −1 ) and CZTS (34.42 μmol g −1 h −1 ), respectively. The mechanism study revealed that the excellent superior H 2 evolution performance resulted from the established internal electric field (IEF) in p-n heterojunction, which expedites the efficient separation and migration of photoinduced carriers coupled with the distinctive flower-like configuration of CZTS offering a substantial surface area and enough active reduction sites for photocatalysis process. This work presents a rational design and an inexpensive and efficient heterojunction photocatalysis system suitable for diverse applications.

Pest management is mostly accomplished by the use of insecticides. However, the overuse of insecticides has led to the development of resistance. Glutathione S-transferases (GSTs) are vital detoxification enzymes involved in insecticide resistance in insects. In this study, we report the involvement of GSTs in insecticide resistance to lambda-cyhalothrin in Cydia pomonella, a globally quarantined fruit pest. A total of 25 GST, including 22 cytosolic genes and 3 microsomal genes, are identified from the genome database of C. pomonella. These cytosolic genes are further classified into six classes, including four in delta, eight in epsilon, three in omega, three in sigma, one in theta, and one in zeta class, as well as two unclassified genes. The real-time quantitative polymerase chain reaction (RT-qPCR) shows that the majority of these genes are mainly expressed throughout the larval stage and in the midgut of the fourth-instar larvae. Exposure to an LD10 dose of lambda-cyhalothrin resulted in the upregulation of 17 GST genes. Moreover, mRNA levels of most GST genes, with the exception of CpGSTe6, CpGSTd2, CpGSTd4, and CpGSTz1, are considerably higher in a lambda-cyhalothrin-resistant population (ZW_R) than those of susceptible strains. Recombinant CpGSTd1, CpGSTd3, CpGSTe3, and CpGSTs2 can bind and metabolize lambda-cyhalothrin, with the highest metabolic rate observed for CpGSTd3 but no metabolite(s) was detected, supporting the role of GSTs in sequestration of lambda-cyhalothrin. Molecular dynamics simulation analysis indicates that key residues of hydrophobic pocket-derived lipophilic energy S(lipo) interactions with a hydrophobic pharmacophore of lambda-cyhalothrin are crucial for metabolism by CpGSTd3 and further lead to resistance. Our study is the first to experimentally confirm the involvement of GSTs in lambda-cyhalothrin resistance via sequestration and provides new insights into resistance management in C. pomonella.
