ZnS materials have been widely used in fluorescence biosensors to characterize different types of stem cells due to their excellent fluorescence effect. In this study, ZnS was prepared by vulcanizing nano-Zn particles synthesized using a DC arc plasma. The composition and structure of the ZnS materials were studied by X-ray diffraction (XRD), and their functional group information and optical properties were investigated by using IR spectrophotometry and UV-vis spectrophotometry. It has been found that the synthesized materials consist of Zn, cubic ZnS, and hexagonal ZnS according to the vulcanization parameters. Crystalline ZnS was gradually transformed from a cubic to a hexagonal structure, and the cycling properties first increase, then decrease with increasing sulfurization temperature. There is an optimal curing temperature giving the best cycling performance and specific capacity: the material sulfurized thereat mainly consists of cubic β-ZnS phase with a small quantity of Zn and hexagonal α-ZnS. The cubic phase ZnS has better conductivity than hexagonal ZnS, as evinced by electrochemical impedance spectroscopy (EIS). The ZnS (as prepared) shows board absorption, which can be used in fluorescence biosensors in cell imaging systems.

ZnS has acquired increasing attention for high‐performance PIBs anode because of its remarkable theoretical capacity, and redox reversibility for conversion reaction. However, the larger volume variation and delayed reaction kinetics for the ZnS in the discharge/charge processes lead to pulverization and severe capacity degradation. Herein, the trumpet‐like ZnS@C composite was synthesized by template method by using sodium citrate as carbon source followed by vulcanization process. As potassium ion batteries (PIB) anode, ZnS@C composite exhibits good rate performance and long life (stable reversible capacity of 107.8 mAh/g over 2000 charge‐discharge cycles at 5 A/g and high reversible capacity of 310 mAh/g at 0.1 A/g). The outstanding electrochemical performance of the ZnS@C composite is ascribed to its unique structure, which can mitigate the volume expansion of ZnS in the charge discharge process, expand the contact area between the electrode and electrolyte, and improve the conductivity of electrode materials by the introduction of carbon layer. This method of synthesizing trumpet‐like ZnS@C composite provides an important strategy for obtaining potassium ion batteries anode with long cycle.

“…Metal sulfides, such as ZnS, − MoS 2 , , CuS, , SnS 2 , , TiS 2 , , etc., have received extensive attention as a result of their unique properties as the anode. In particular, ZnS has been extensively studied because of its low cost and non-toxic properties. ,− Nevertheless, on account of the disadvantages of large volume change during charging and discharging, wider band gap, and poor mechanical properties, graphene coating, ,, porous carbon coating, , biomass carbon coating, amorphous carbon coating, and other methods , have been developed to improve its electrochemical performance. Among them, the ZnS/graphene composite shows excellent cyclability with a high specific capacity.…”

First-Principle Study of a ZnS/Graphene Heterostructure as a Promising Anode Material for Lithium-Ion Batteries

Properties of ZnS/graphene, such as formation energy of the Li adatom, activation energy for Li diffusion, pseudocapacity-like storage, and density of state (DOS), render ZnS/graphene a suitable anode material for a rechargeable lithiumion battery. Lithium storage sites, migration paths, electronic conductivity, and storage sequence of lithium ions are clarified. Lithium ions preferentially embed the ZnS/graphene heterostructure interface and the surface of ZnS and then intercalate into the bulk phase of ZnS. In the ZnS bulk, Li ions diffuse by the T−O−T path, and the activation energy diseases with volume expanded. LiS 4 and ZnS 2 are produced with ZnS lithiation, besides Li x Zn and Li 2 S. Moreover, it is proven that the capacity of ZnS/ graphene more than the sum of ZnS and graphene originates from the interfacial lithium storage via the pseudocapacity-like storage mechanism. Therefore, further increasing the contact area between ZnS and graphene could promote the capacity by reducing the ZnS particle size.
