Aqueous hybrid-ion batteries (AHBs) offered various advantages, including low cost, high energy density, high operation voltage, safety, and durability. These characteristics made them an attractive choice for energy storage devices. CuS was a high-capacity cathode material for Al storage. However, the rate performance of CuS under high-voltages conditions was not satisfying. Here, we prepared Co-doped CuS (Co-CuS) nanosheet material with the small band gap by using the ball milling method as the cathode material of aqueous Cu-Al hybrid-ion battery. Co doping can improve the electron transport capacity and provide more active sites. At high current density, Co doping enhances the electrochemical kinetics, operating voltage and electrochemical performance of the materials. The battery exhibits a capacity of 175 mAh g -1 at 2000 mA g -1 and 108 mAh g -1 at 4000 mA g -1 . After 200 cycles of charge and discharge tests, a capacity of 93 mAh g -1 remains. This offers a valuable approach to the development of aqueous Cu-Al hybrid-ion battery electrode materials with good electrochemical performance under high operating voltage and high current conditions.

Graphical Versatile nanoparticle : A facile one-pot approach for the preparation of a versatile CuS/Gd 2 O 3 hybrid nanoparticle, which is used as a theranostic agent for magnetic resonance imaging and synergistic cancer therapy, has been developed. The versatile application of nanoparticles in integrating imaging and therapy has aroused extensive research interest in precision medicine. Of the various nanoparticles that have been studied, CuS has shown great potential in the construction of multifunctional agents, owing to its excellent photothermal heating properties. Herein, we report a facile one-pot biomineralization approach for the preparation of versatile bovine-serum-albumin-conjugated CuS/Gd 2 O 3 hybrid nanoparticles (BSA−CuS/Gd 2 O 3 HNPs), which simultaneously possessed strong longitudinal relaxivity, an outstanding photothermal effect, high drug-loading capacity, and pH/temperature-responsive drug release. The versatile nanoparticles were used for magnetic resonance imaging (MRI) and antitumor photothermal chemotherapy, both in vitro and in vivo. In vivo MRI showed that the BSA−CuS/Gd 2 O 3 HNPs had a long circulation time and effective passive tumor-uptake ability. More importantly, combined in vitro and in vivo therapy demonstrated that drug-loaded BSA−CuS/Gd 2 O 3 HNPs offered outstanding synergistic therapeutic efficacy for tumor inhibition.

In this study, TiO2/CuS nanocomposites with cauliflower-like protrusions were successfully prepared using a simple one-step hydrothermal method with the assistance of 3-mercaptopropionic acid (3-MPA). The TiO2 and CuS formed heterojunction materials with a stable crystal phase during hydrothermal treatment. The as-prepared TiO2/CuS was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet-visible diffuse reflectance spectroscopy (DRS) and X-ray photoelectron spectroscopy (XPS). Besides, the photocatalytic performance of the nanocomposite material was detected in Rhodamine B (RhB) solution. Results indicate that TiO2/CuS nanocomposites exhibit higher photocatalytic performance than the TiO2 and CuS controls, this can be attributed to their distinctive morphology, strong light absorption capacity and effective promotion of the heterojunction between TiO2 and CuS.

Nanomaterials with enzyme-like activity have attracted much attention recently. Herein, we report the synthesis of a new type of 2D MXene-Ti 3 C 2 /CuS nanocomposites with peroxidase-like activity using a simple hydrothermal approach. Significantly, compared with the individual MXene-Ti 3 C 2 nanosheets or CuS nanoparticles, the MXene-Ti 3 C 2 /CuS nanocomposites show a synergistically enhanced peroxidase-like activity and can be used as an efficient mimetic peroxidase to catalyze the reaction of 3,3,5,5-tetramethylbenzidine (TMB) in the presence of hydrogen peroxide (H 2 O 2 ), causing a blue color change. Kinetic studies reveal that the MXene-Ti 3 C 2 /CuS nanocomposites have a higher catalytic activity to TMB than their single components, and the catalytic reaction follows the ping-pong mechanism. The MXene-Ti 3 C 2 /CuS nanocomposites are used for the colorimetric determination of cholesterol with a linear range of 10–100 μM and a limit of detection (LOD) of 1.9 μM. Our results show that the MXene-Ti 3 C 2 /CuS nanocomposites based colorimetric cholesterol biosensor is cost-effective, sensitive, and selective, which has potential application in H 2 O 2 and cholesterol detection and clinic medicine diagnostics.

The design and fabrication of eco-friendly, highly efficient, and non-noble-metal-based catalysts are demanding challenges in energy-conversion technologies. Herein, we successfully synthesized CuS nanosheets decorated with CoS2 nanoparticles through a facile route. The optimized 3% CoS2-7% CuS catalysts exhibited remarkable electrocatalytic performance, with excellent cyclic stability at all pH values for the hydrogen evolution reaction (HER). They exhibited lower Tafel slopes (46, 52, and 59 mV dec–1) and smaller overpotentials (62, 85, and 106 mV) at 10 mA cm–2 in 0.5 M H2SO4, 1 M KOH, and 0.5 phosphate buffer aqueous solutions, respectively, than other CoS2/CuS, pure CoS2, and pure CuS catalysts. We attribute their high electrocatalytic performance to their unique heterostructure and the synergistic effects between the constituent metal sulfides that provides a large interfacial contact area, numerous charge-transfer pathways, as well as abundant surface reaction active sites, enhancing the charge-carrier transfer during the HER activity.

Developing antibacterial hydrogels, with good mechanical strength and self-healing ability to resist bacterial invasion and accelerate skin regeneration, is critical for infected full-thickness skin wound treatment. Herein, we report a gelatin-assisted synthesis and direct incorporation strategy to construct a CuS hybrid hydrogel for infected wound healing applications. CuS nanodots (NDs) were synthesized directly inside a gelatin host matrix (Gel-CuS), and these tightly confined and evenly distributed CuS NDs displayed superb dispersibility and stability against oxidation. Gel-CuS was then used to crosslink with oxidized dextran (ODex) to form a Gel-CuS-8/ODex hydrogel (8 stands for the concentration of CuS, in mM) via a facile Schiff-base reaction, which exhibited improved mechanical properties, excellent adhesion and self-healing ability, suitable swelling and degradation behavior, and good biocompatibility. The Gel-CuS-8/ODex hydrogel can act as an efficient antibacterial agent due to its photothermal and photodynamic properties under a 1064 nm laser irradiation. Furthermore, in animal experiments, when being applied as wound dressing, the Gel-CuS-8/ODex hydrogel significantly promoted infected full-thickness cutaneous wound healing through improved epidermis and granulation tissue formation and accelerated generation of new blood vessels, hair follicles, and collagen deposition after proper near-infrared irradiation treatment. This work provides a promising strategy to synthesize functional inorganic nanomaterials tightly and evenly embedded inside modified natural hydrogel networks for wound healing applications.

Photothermal therapy as a physical therapeutic approach has greatly attracted research interest due to its negligible systemic effects. Among the various photothermal agents, CuS nanoparticles have been widely used due to their easy preparation, low cost, high stability and strong absorption in the NIR region. However, the ambiguous biotoxicity of CuS nanoparticles limited their bio-application. So it is highly desirable to develop biocompatible CuS photothermal agents with the potential of clinical translation. Herein, we report a novel method to synthesize biocompatible CuS nanoparticles for photothermal therapy using bovine serum albumin (BSA) as a template via mimicking biomaterialization processes. Owing to the inherent biocompatibility of BSA, the toxicity assays in vitro and in vivo showed that BSA–CuS nanoparticles possessed good biocompatibility. In vitro and in vivo photothermal therapies were performed and good results were obtained. The bulk of the HeLa cells treated with BSA–CuS nanoparticles under laser irradiation (808 nm) were killed, and the tumor tissues of mice were also successfully eliminated without causing any obvious systemic damage. In summary, a novel strategy for the synthesis of CuS nanoparticles was developed using BSA as the template, and the excellent biocompatibility and efficient photothermal therapy effects of BSA–CuS nanoparticles show great potential as an ideal photothermal agent for cancer treatment.

Modifying the electronic structure of electrocatalysts by metal doping is favorable to their electrocatalytic activity. Herein, by a facile one-pot redox process of Fe(III) and Cu(I), Fe(II) was successfully doped into the subsurface of CuS nanosheets (NSs) for the first time to obtain a novel electrocatalyst (Fesub-CuS NSs) that possesses not only subtle lattice defects but also an atomic-level coupled nanointerface, greatly enhancing the oxygen evolution reaction (OER) performances. Meanwhile, Fe(II) and Fe(III) coexisting in Fesub-CuS nanosheets are favorable to OER through valence regulation. As expected, by simultaneously controlling the abovementioned three factors to optimize Fesub-CuS nanosheets, they display a lower overpotential of 252 mV at a current density of 20 mA cm–2 for OER, better than 389 mV for pristine CuS nanosheets. This discovery furnishes low-cost and efficient Cu-based electrocatalysts by metal doping. Density functional theory (DFT) calculations further verify that Fesub-CuS(100) is thermodynamically stable and is more active for OER. This research provides a strategy for the atomic-scale engineering of nanocatalysts and also sheds light on the design of novel and efficient electrocatalysts.

Designing and synthesizing the excellent heat storage and photothermal integrated composite phase change materials (PCMs) is an effective strategy for solar energy utilization. This work focuses on two kinds of CuS (cuboidal and 3D flower-shaped) with different morphology were designed as substrates and photothermal materials, and PA/F–CuS and PA/C–CuS composite PCMs have been prepared by melt-blending and vacuum impregnation method. Through SEM and pore structure characterization as well as leakage testing, it is proved that 3D layered flower-shaped CuS not only exposes the large specific surface area and rich adsorption sites, but also 2D thin layers can perform multiple reflections to improve the utilization rate of solar energy. The flower-shaped CuS is more suitable for the supporting material. Noteworthy, the latent heat of PA/F–CuS can reach 226.3 J/g, and the thermal conductivity is 0.3447 W/(m·K). Furthermore, compared with pure PA, the photothermal property of PA/F–CuS increased by 49.22–84.59%, and the photothermal conversion efficiency can reach 70.3%. This work provides an innovative idea for the design and manufacture of composite PCMs related to medium and low temperature solar energy storage, and has broad application potential in the field of thermal energy storage such as solar energy utilization and building insulation materials.

At present, the development of lightweight and wideband microwave absorbing materials with stable infrared stealth property and adaptable to complex environments has become the key to multi-modal stealth technology . Herein, hollow CuS microflowers were self-assembled on biomass-derived porous carbon in situ to realize the multifunctions of microwave absorption, flame retardance and thermal stealth. The multicomponent synergistic effect combined with unique microarchitecture triggered the multiple polarization effects , multiple reflection and scattering as well as conduction loss in the PC@CuS composite. As a result, the PC 800 @CuS sample exhibited an optimal RL min of −61.5 dB and an exceptionally wide EAB of 7.8 GHz with the filling ratio of only 10%. In addition, the PC@CuS composite also exhibited superior flame-retardant properties by virtue of its distinctive porous structure . Meanwhile, the uniform distribution of CuS particles played a vital role in enhancing the overall infrared absorption efficiency, thereby obtaining stable and highly-effective infrared stealth performance comparable to commercial products. This work shed light on the development of high-efficiency MAs with multifunctions in a facile and low-cost manner.

Recently, transition metal sulfides (TMSs) have attracted great attention because of their abundant valence states and remarkable electrochemical activity in the field of supercapacitors. However, it is still a great challenge to prepare TMSs with high specific capacitance, good rate performance, and remarkable cycle stability. Herein, the microflower-like CuS/Co 3 S 4 composite was achieved through an efficient two-step procedure. Firstly, the microflower-like CuCo precursors consisting of ultrathin nanoflakes were prepared by a simple solvothermal reaction. Subsquently, the CuS/Co 3 S 4 composites with microflower-like microstructure, rich in nanoflakes, almost the same with the precursors, were obtained using Na 2 S·9 H 2 O as the sulfur source through a simple hydrothermal treatment. Ascribing to the distinctive microflower structure and bimetallic sulfides synergy, the CuS/Co 3 S 4 electrode shows a notable specific capacitance (1483 F g −1 at 1 A g −1 ) and an impressive rate performance (1038.1 F g −1 at 20 A g −1 ). Furthermore, the assembled hybrid supercapacitor CuS/Co 3 S 4 //PC displays a considerable energy density of 55.02 Wh kg −1 at the power density of 372.5 W kg −1 , and a distinguished cycle performance. This study provides valuable insights into the development of novel bimetallic sulfides for potential application in supercapacitors.

Photothermal therapy, assisted by local heat generation using photothermal nanoparticles (NPs), is an emerging strategy to treat tumors noninvasively. To improve treatment outcomes and to alleviate potential side effects on normal tissue cells, utilizing the optically transparent second near-infrared (NIR-II) window and actively targeting tumors are critical. Considering that mitochondria are heat sensitive and play an important role in the up-regulation of metabolic activity in tumor cells, herein we report a cascade targeting scheme that enables active photothermal ablation of tumor mitochondria. First, NIR-II absorbing CuS NPs were surface modified with the mitochondria targeting moiety (3-carboxypropyl) triphenylphosphonium bromide (TPP) and then shielded with CD44 targeting hyaluronic acid, which will only expose TPP upon reaching the tumor sites. This allowed over 90% CuS NP enrichment at tumor mitochondria, and as a result, significantly improved tumor cell photothermal ablation was observed at the cellular level. An in vivo study demonstrated enhanced tumor uptake and improved tumor growth suppression by using these cascade targeting CuS NPs as NIR-II photothermal agents.
