“…Due to the swift rate of precipitation, it is difficult to control the morphology of produced samples. 12 Ebnelwaled et al 119 studied the synthesis of ZnS nanoparticles through chemical precipitation using zinc nitrate hexahydrate (Zn(NO 3 ) 2 •6H 2 O) as a zinc source and sodium sulfide (Na 2 S•H 2 O) as the sulfur source. XRD revealed ZnS nanoparticles having cubic phase with an average crystallite size of 6.41 nm.…”

Supercapacitors have increased considerable interest due to their unique characteristics such as extended life cycle, high-power density, and environmental friendliness. They serve as a bridge for the energy-power difference between a traditional capacitor and batteries/fuel cells. Selection of the ideal electrode material for a particular application is a critical parameter that affects the efficiency of supercapacitor devices. Transition-metal sulfides exhibit multiple oxidation states and display outstanding supercapacitance performance. Metal sulfides are comparatively superior than metal oxides because of their better conductivity, higher electrochemical activity, and eminent thermal and mechanical stability. A comprehensive summary of the zinc sulfide (ZnS)-based nanomaterials as supercapacitor electrodes is on view. With a band gap of 3.5−3.8 eV, ZnS is one of the first discovered II−VI semiconductors. ZnS has been revealed as a sustainable and promising supercapacitance electrode material owing to its facile synthesis and magnificent electrochemical performance. This review has covered the recent research and development of ZnS nanostructures for supercapacitor electrodes. Additionally, synthesis of ZnS nanostructures and influencing parameters, selection of composite materials, and their design have been summarized for highly efficient supercapacitor devices. As far as our knowledge, this review is the first holistic description of ZnS-based supercapacitor electrodes and devices from basics to recent advancements.

Lead Sulphide (PbS) nanoparticles were processed using ball milling techniques. The processed PbS nanoparticles were characterized using atomic absorption spectroscopy (AAS), X-ray diffraction (XRD), scanning electron microscopy (SEM),, energy dispersive analysis (EDAX), and electrical investigation using four-point probe. The XRD results of the PbS nanoparticles show peaks at the crystal plane (111), (200), (210), (211) and (320). The average size of PbS nanoparticles crystallite is found to be 51.05 nm. The optical energy band gap of PbS nanoparticles dispersed in ethanol was observed to be 3.98ev and 4.06eV for PbS nanoparticles dispersed in distilled water. The absorbance of PbS nanoparticles shows that the absorbance values were moderate in the UV region but dramatically decreased as they moved towards the visible and near-infrared regions. The EDX analysis shows that PbS nanoparticles is composed of 54.36% Pb, 36.47% C and 9.16% S. The sheet resistance, resistivity, and conductivity were measured and found to be 1.51 × 107 Ω/Sq., 3.61 Ω.cm and 2.77 × 10-1 (Ω.cm)-1 for PbS nanoparticles. PbS nanoparticles are classified as promising materials for various electronics and optoelectronic devices based on the determined properties.

Zinc sulphide nanoparticles capped with hexadecylamine (ZnS-HDA) have been synthesized through thermal decomposition of (Z)-2- (pyrrolidin-2-ylidene)thiourea zinc(II) complex. The effects of temperature, time and concentration of the precursor on the properties of ZnS-HDA capped nanoparticles were investigated. The values of the optical band edges were increasing when the temperature, reaction tim and the amount of the precursor were elevated. X-ray diffraction patterns of all the synthesized nanoparticles mainly exhibited hexagonal phase structures. The morphologies of the particles were increasing with the increase in temperature, time and precursor concentration.
