Hollow Mo-doped NiSx nanoarrays decorated with NiFe layered double-hydroxides for efficient and stable overall water splitting

“…S11 †). 47 Hence the hollow arrays aer vulcanization hold higher specic surface area than the micron nanorod, which can be well visualized from the SEM images in Fig. 2a-c.…”

Advances on Nickel-Based Electrode Materials for Secondary Battery Systems: A Review

“…Meanwhile, the well-distributed phase interface in MoS 2 −NiS prevented the material from agglomeration during charging and discharging. 84 Although heterostructures possessed huge potential in controlling the shuttle effect of soluble lithium polysulfides, the capability of limiting the huge expansion was not as good as expected. Therefore, carbon shells with confinement effects have been further explored in ESSs.…”

“…Moreover, in the MoS 2 –NiS heterostructure, the enhancement of electrochemical performance was regarded as the result of defects introduced by the heterostructure. Meanwhile, the well-distributed phase interface in MoS 2 –NiS prevented the material from agglomeration during charging and discharging …”

“…Attaching 2D ReS 2 nanosheets on the surface of NiS 2 hollow spheres, ReS 2 @NiS 2 with hollow structures was successfully fabricated. Excitedly, the surface faradaic charge-transfer reactions were brought about by the complex 3D structure, which boosted pseudocapacitive properties of ReS 2 @NiS 2 (72,80,84,87, and 88% at 0.1, 0.2, 0.4, 0.6, and 0.8 mV/s). Besides, benefiting from the hollow structure, ReS 2 @NiS 2 exhibited a considerable capacity (400 mA h g −1 at 1.0 A g −1 ).…”

Cobalt and oxygen double doping induced C@MoS2–CoS2–O@C nanocomposites with an improved electronic structure and increased active sites as a high-performance anode for sodium-based dual-ion batteries

“…11 One-dimensional MoO 3 nanorods with polymer coating as a template and Mo source for the preparation of MoS 2 composites have aroused wide interest, and a great deal of research has been carried out through a variety of methods, such as the hydrothermal method, the solvothermal method and laser irradiation. [12][13][14] For example, MoS 2 -NiS nanosheets coated with N-doped carbon by using MoO 3 nanorods as a template were reported by Yang et al 15 Polypyrrole (PPY) is a conductive polymer with good mechanical properties and is a carbon material with superior electrical conductivity aer heat treatment. The method of using MoO 3 nanorods with PPY coating as a template to synthesize MoS 2 composites has good controllability, repeatability and universality.…”
