Different phases of cobalt sulfides have been fabricated by one-pot hydrothermal method. Comparing all of the prepared materials, and the results revealed that CoS was the most conductive and could accelerate electron transfer. The CoS presented tremella-like and excellent catalytic activities towards hydrogen peroxide and glucose. The sensor based on CoS performed amperometric sensing of hydrogen peroxide in a linear range between 5.00 μM and 14.82 mM. Meanwhile, sensing of glucose with double-linear range, one is between 5.00 μM and 1.10 mM, the other is between 1.20 mM and 10.20 mM. These due to the fact that more and more intermediate species absorb onto electrode surface with increasing the concentration of glucose, which limit the following glucose oxidation. Furthermore, the hydrogen peroxide and glucose sensors based on tremella-like CoS also exhibited excellent selectivity, stability, and reproducibility. Thus, the sensor showed potential utilities in hydrogen peroxide and glucose detection.

A hierarchical CoS shelled Cu 2 S nanorods material grown directly on copper foam (denoted as Cu 2 S NRs@CoS/CF) was prepared for the first time and used as the bifunctional electrocatalyst for both OER and HER in 1 M KOH solution. Resulting from the substrate-integrated synthesis, the highly open spaces and the synergistic effects between Cu 2 S and CoS active components, the as-obtained core-shell heterostructure and its derivative behaves as a remarkable active bifunctional electrocatalyst towards both water oxidation and hydrogen evolution reaction in 1 M KOH solution (pH 13.7), which only need low overpotentials of 275 and 235 mV to deliver the current density of 50 mA cm −2 with Tafel slopes of 54 and 121 mV dec −1 for OER and HER, respectively, rivalling the catalytic efficiency of most published non-noble metal catalysts . Furthermore, the fabrication strategy presented here is facile and economical which might offer some insights for fabricating other novel water splitting catalysts with high activity.

Graphical An efficient method for preparing benzothiazolone derivatives was developed by a domino coupling reaction between the disulfide and COS in the present of NaOH. Notably, the C=O of COS was converted into benzothiazolone by carbonylation reaction and the sulfur of COS was transformed into sulfur and sulfide after cleaving the S–S bond under mild conditions. This efficient synthetic methodology could provide a promising process for the utilization of COS. Carbonyl sulfide (COS), whose molecular structure is similar to CO 2 and CS 2 , could be used as a better alternative carbonyl reagent due to its high chemical activity. However, the unfriendly by-product H 2 S would be generated when COS is used as a carbonyl reagent in the carbonylation reaction. In this report, the odorless and stable disulfide was used to replace the traditional foul smelling and unstable o -aminobenzenethiol to react with COS for preparing benzothiazolone derivatives in excellent yield, in which coupling reaction of H 2 S generation and S–S bond cleavage was firstly designed. Notably, the C=O of COS was converted into benzothiazolone derivatives by carbonylation reaction and the sulfur of COS was transformed into sulfur and sulfide after cleaving the S–S bond by a domino reaction of disulfide and COS under mild conditions. This efficient synthetic methodology provided a promising process for the utilization of COS.

Benefitting from the large interlayer spacing, ultrahigh conductivity and abundant surface chemistry, Ti 3 C 2 T x has been a promising electrode material for supercapacitors (SCs). CoS has attracted much attention due to its low cost, weak Co-S bond and relatively high theoretical capacity. Herein, CoS nanowires were grown on few-layered Ti 3 C 2 T x by one-step solvothermal method as a SC electrode. Within the composite, Ti 3 C 2 T x could function as conductive network and buffer matrix to provide ultra-fast electronic transport and relieve volume expansion of CoS nanowires. Simultaneously, the active CoS nanowires with high capacitance act as interlayer spacer to restrain the restacking of Ti 3 C 2 T x nanosheets . As a result, CoS/Ti 3 C 2 T x -5 electrode exhibits a remarkable improvement specific capacitance of 528 F g −1 at a current density of 1 A g −1 and ultrahigh capacitance retention of 99.3% after 20 000 cycles at a current density of 10 A g −1 . The attempts and efforts made in this work provide a prototype for achieving excellent electrochemical properties .

Supercapacitors are indispensable for next-generation energy storage, achieving high energy density and long-term durability remains a formidable challenge. Conventional CoS suffers from poor conductivity, while Ti 3 C 2 faces severe restacking. Herein, we report a novel synthesis strategy that integrates metal-organic framework (MOF) growth with electrostatic self-assembly to construct heterojunction of CoS nanotubes coated with ultrathin Ti 3 C 2 nanofilms. Material characterization via SEM, TEM, XRD, and XPS systematically confirms the heterostructure formation, and chemical composition. This rational design synergistically leverages CoS high pseudocapacitance and Ti 3 C 2 metallic conductivity while the heterostructure mitigates restacking, enhances charge transfer, and stabilizes interfacial interactions. Density functional theory (DFT) calculations reveal strengthened OH - adsorption at the Co-Ti interface (E ad = 1.106 eV). Consequently, the CoS/Ti 3 C 2 @CC delivers a remarkable specific capacitance of 1034.21 F g -1 at 1 A g -1 . Assembled into a supercapacitor, CoS/Ti 3 C 2 @CC//AC achieves a high energy density of 74.22 Wh kg -1 at 800 W kg -1 , maintaining 89.13% initial capacitance after 10,000 cycles. Significantly, it exhibits a remarkably low leakage current (0.23 μA) and ultra-prolonged voltage retention (47.14% after 120 h), underscoring exceptional durability. This work pioneers a rational heterostructure engineering strategy by integrating MOF-derived architectures with conductive MXene nanofilms, offering critical insights for the development of ultra-durable supercapacitor.

Primary amines are widely employed for Carbonyl sulfide (COS) removal owing to their rapid reactivity, yet insufficient regeneration remains a critical bottleneck for cyclic utilization. This limitation essentially arises from the lack of quantitative understanding of the coupling among absorption, hydrolysis, and desorption. In this study, nine primary amines were systematically evaluated, and their behaviors in absorption, hydrolysis, and desorption were integrated with molecular descriptors to construct a quantitative framework. The results showed that DL-2-aminobutanol (DL-2-AP) and 1-aminopropanol (1-AP) achieved nearly complete COS removal with hydrolysis yields of 60 %, stable regeneration with only a 5 % decline over five cycles, and lower regeneration energy than ethanolamine (MEA, >4300 kJ/mol), thereby showing the most favorable overall performance. Further analysis suggested that molecular features including Minimum Electrostatic Potential (ESP min ) around −2 eV, Highest Occupied Molecular Orbital (HOMO) energy on the order of −31 kJ/mol, viscosity near 0.9 cP, Mean SHI within 70–90 kJ/mol, and pKa in a mildly alkaline range (approximately 9–10) together with balanced solubility-activity were statistically associated with more favorable coupling of absorption, hydrolysis, and desorption. Moreover, multiple linear regression models based on ESP min , mean steric hindrance index (Mean SHI), and pKa showed high accuracy (R 2 = 0.85–0.97), suggesting that absorption and desorption exhibited the strongest statistical association with ESP min , whereas hydrolysis was most strongly associated with pKa within this regression based framework. This study establishes a predictive framework bridging molecular design with industrial COS removal, offering descriptor based insight and practical guidance.

The sluggish redox reactions and the shuttle effect associated with lithium polysulfides significantly impede the advancement of LSBs. To solve these problems, we synthesized CoS-FeS heterostructures supported by N-doped carbon nanocage (CoS-FeS@NC). The kinetic analysis shows that the enriched heterojunctions strengthens the bonding of host with polysulfides, thus promotes the redox reaction kinetics of polysulfides. XPS analysis reveals valence state of cobalt is elevated following incorporation of iron. This increase is attributed to the transfer of electrons from Co 2+ /Co 3+ to Fe 3+ . The configuration of the cationic valence electrons drives this electron transfer, which in turn improves the catalytic efficiency of the CoS-FeS@NC composites. Leveraging these advantages, the S@CoS-FeS/NC cathode demonstrates an exceptional ability to adsorb lithium polysulfides (LiPSs), along with rapid reaction kinetics and enduring stability in cycling (reversible capacity of 638 mAh g −1 at 0.2 C after 200 cycles). Remarkably, even when subjected to a charge/discharge rate as high as 1 C, the cathode sustains a capacity of 619 mAh g −1 and it keeps 542 mAh g −1 at 1 C after 1000 cycles at a degradation rate of merely 0.05 % for each cycle. This offers a feasible strategy to thoughtfully fabricate bimetallic sulfide heterostructures and fosters advancements in various electrochemical energy storage and conversion applications.

Cobalt sulfide composites have exhibited great potential in terms of microwave absorption, owing to their low price, relatively high capacitance, and excellent electrocatalytic activity. Thus, a novel core-shell like structure comprising cobalt sulfide@polypyrrole (CoS@PPy) composite was synthesized by a facile solvothermal synthesis method and in situ polymerization. When coated by the heterostructure polypyrrole aerogel, CoS@PPy composite exhibited excellent microwave absorption properties with an optimal reflection loss (RL) of −41.8 dB at 6.96 GHz. Furthermore, the absorption bandwidth (RL< −10 dB) of 5.4 GHz could be reached at a coating thickness of 2.05 mm, probably attributing to the synergistic effect of good impedance matching, interfacial polarization, dipole polarization, and conductivity loss. Moreover, this work proposed a loss mechanism mode which probably occurred in the CoS@PPy composites. It was demonstrated that the CoS@PPy composite is a promising material in the field of electromagnetic wave absorption.Keywords:microwave absorption;CoS;PPy;core-shell structure

Transition metal sulfides (TMSs) are highly promising electrocatalysts for the oxygen evolution reaction (OER), but insufficient stability limits their application. To this end, we prepared cobalt-based nitrogen-doped carbon nanotube-supported binary sulfide heterojunction catalysts (CoS 2 /NiS@Co@NCNTs) via a two-step high-temperature pyrolysis-sulfurization method. The energy-band structure of CoS 2 matches that of NiS, a feature that enables the formation of a high-quality interface, this accelerates electron transfer and charge redistribution, and enhances reaction kinetics. In contrast, the cobalt-based NCNTs enhance electrical conductivity and improve the reaction stability of CoS 2 and NiS. As expected, the CoS 2 /NiS@Co@NCNTs had high OER catalytic activity with an overpotential of 256 mV at a current density of 10 mA cm −2 , which was superior to that of commercial RuO 2 (η 10 = 293 mV). In addition, the prepared catalysts showed good stability and no significant degradation after 50 h of i-t test at a current density of 10 mA cm −2 . This study provides a new strategy for achieving efficient OER in overall water splitting.

Metal sulfides are attractive anodes for sodium-ion batteries due to their high capacity and low polarization. However, single metal sulfides suffer from severe volume changes and sluggish kinetics. Constructing heterostructures offers a promising strategy, yet rational designs that achieve genuine ultra-fast charging capability remain scarce. Herein, we report metallic disc-like CoS/V 3 S 4 heterostructures encapsulated in nitrogen‑sulfur co-doped carbon (CoS/V 3 S 4 @NSC). When evaluated with an ether-based electrolyte, the optimized CoS/V 3 S 4 @NSC exhibits high initial Coulombic efficiency (>90%), high reversible capacity (622.6 mAh g −1 at 0.5 A g −1 ), excellent stability (291.5 mAh g −1 after 300 cycles at 15 A g −1 ), and remarkable ultra-fast charging capability (143.1 mAh g −1 at 40 A g −1 within 12 s). Combined in situ/ex situ studies and density functional theory calculations reveal metallicity, enhanced Na + diffusion, and a pseudocapacitive-dominated conversion mechanism. Full cells assembled with Na 3 V 2 (PO 4 ) 3 @rGO cathodes further demonstrate long-term stability (414.1 mAh g −1 after 1500 cycles at 1 A g −1 ) and outstanding rate capability (324.8 mAh g −1 at 5 A g −1 ). This work highlights a rational heterostructure design that enables practical ultra-fast sodium-ion storage. N,S co-doped carbon encapsulated disc-like CoS/V 3 S 4 heterostructures manifest remarkable ultra-fast charging ability as advanced sodium-ion battery anodes. Various in situ/ex situ studies and DFT calculations confirm metallicity, boosted Na + diffusion, and pseudocapacitive dominated conversion mechanism. The assembled high-performance full cells demonstrate the possibility of rational heterostructure design for practical ultra-fast sodium-ion storage.

Electrocatalytic nitrate (NO3‒) reduction reaction (eNO3RR) is a promising route for ammonia (NH3) synthesis to alternate Haber-Bosch process. It is important to design catalysts with high efficiency and strong selectivity for the preparation of NH3 via the eNO3RR. Herein, a ZIF-derived nitrogen-doped carbon/cobalt sulfide electrocatalyst, CoS@CN, with a hollow cage structure synthesized by vulcanization etching, is presented as a high-efficiency electrocatalyst for eNO3RR. CoS@CN shows outstanding selectivity and stability with a large NH3 yield of 4.74 mg h-1 mcat-1 at -0.75 V vs. RHE and a high Faradaic efficiency of 97.88% at -0.35 V vs. RHE in 0.1 M NaOH with 200 ppm NO3‒. Density functional theory calculations demonstrate that CoS@CN has a narrower bond gap (0.16 eV) and lower barrier potential determining step (0.71 eV). The S atoms function as bridges connecting the charge repository C atoms to the active site Co atoms, as is more favorable for NH3 synthesis through the eNO3RR. It was demonstrated both experimentally and theoretically that the S element plays an important role. The introduction of the S element could not only modulate the electronic structure of the catalysts, but also modulate the morphology of the catalysts to a hollow cage structure, as facilitates the proceeding of eNO3RR. This work offers a promising strategy for designing high-performance eNO3RR catalysts for electrocatalytic NH3 synthesis and the waste water treatment.
