“…[35] The final weight of the ZnS/NiO nanocomposite is 89.4 % which is more thermally stable than ZnS. [38] The DSC associated with TGA of ZnS/NiO nanocomposite exhibited the heat flow change with temperature and was used to determine the melting and crystallization temperature. The crystallization temperatures of composite were evaluated as 567 °C and 801 °C.…”

Supercapattery is an ideal energy storage device combining the features of supercapacitors and batteries, offers a high‐energy density as well as high‐power density with extended operational lifespan. In this work, zinc sulfide (ZnS) and zinc sulfide/nickel oxide (ZnS/NiO) nanocomposite was synthesized via chemical coprecipitation method and characterized using state‐of‐the‐art analytical tools. The ZnS/NiO electrode exhibited remarkable electrochemical performance as an electrode material than pure ZnS. The ZnS/NiO nanocomposite exhibited high crystallinity, and spherical nanoparticles with an average grain size of 20–40 nm having a homogeneous dispersion. The ZnS/NiO electrode exhibited an ultrahigh specific capacity of 1803.87 Cg−1 at a relatively low scan rate of 10 mVs−1 in a 1 M KOH solution from cyclic voltammetry and 393 Cg−1 at 16 Ag−1 from charge discharge measurements, and it showed exceptional cycling stability (98 % capacity retention after 1000 cycles). Furthermore, the ZnS/NiO symmetric supercapattery device exhibited 44.43 Fg−1 specific capacitance, 5.52 Wh kg−1 energy density, and 1600 Wkg−1 power density at current density of 0.8 Ag−1 in 1 M KOH solution from galvanostatic charge discharge. After 3000 cycles, the ZnS/NiO nanomaterial demonstrated promising cyclic stability of 95 %. The ZnS/NiO supercapattery nanocomposite might be considered as a potential hybrid electrode material for the future development of electrochemical energy storage devices.

“…Oleic acid modified Fe 3 O 4 NPs were prepared by the coprecipitation method and their surface changed with DMSA in one step after the synthesis and obtained DMSA-coated Fe 3 O 4 NPs [39]. Other examples of nanostructured materials prepared by coprecipitation method are PEG-coated Fe 3 O 4 NPs [40], Ni-Zn-Fe NPs [41], CoFe 2 O 4 NPs [42], Mn-doped ZnO NPs [43], and SiO 2 NPs-polymer composites [44]. The coprecipitation method could also be modified with an external alternating-current magnetic field [45], electric field, microwave or ultrasonic irradiation [46].…”

CHAPTER 1 Liquid-phase synthesis of nanoparticles and nanostructured materials on changing their physical properties; (7) size and shape of NPs and nanostructures could be controlled quite well by the most liquid-phase synthesis methods (depending on the method used). Chemical purification and size separation techniques, such as chromatography and high-performance liquid chromatography (HPLC) are not required; (8) postsynthesis techniques are available for formation of clusters [6] and 2d superlattices [7] from the as-prepared NPs and nanostructures. The liquid-phase synthesis can be classified into: (1) top-down approaches, where bulk materials are etched in an aqueous solution for producing NPs or nanostructures, for example, the synthesis of porous silicon by electrochemical etching; and (2) bottom-up approaches, where atoms/molecules via self-assembly, in general, are gathered together to form NMs and mixed in a controlled fashion to form a colloidal solution (Fig. 1.2). NPs produced by liquid-phase synthesis methods can remain in liquid suspension for further use or may be collected by filtering or by spray drying to produce a dry powder. Liquid-phase synthesis methods from a solution of chemical compounds include, but are not limited to, chemical stain etching, colloidal methods, coprecipitation, electrochemical deposition, direct precipitation, sol-gel processing, microemulsions method, reverse micelle synthesis, hydrothermal synthesis, template methods, polyol method, and laser ablation. In this ■ ■ FIGURE 1.2 Schematic of the formation of NMs processes. Top-down versus bottom-up liquid-phase synthesis methods. ■ ■ FIGURE 1.1 Various methods for formation of NMs. The liquid-phase synthesis is reported as one of the most widespread synthesis technique together with the gas-state synthesis.
