Electrochemical energy storage is a current research area to address energy challenges of the modern world. The Cu 2 FeSnS 4 /PVP/rGO-decorated nanocomposite using PVP as the surface ligand was explored in a simple one-step solvothermal route, for studying their electrochemical behavior by designing asymmetric hybrid supercapacitor devices. The full cell three-electrode arrangements delivered 748 C/g (62.36 mA h/g) at 5 mV/s employing CV and 328 F/g (45.55 mA h/g) at 0.5 A/g employing GCD for the Cu 2 FeSnS 4 /PVP/rGO electrode. The half-cell two-electrode device can endow with 73 W h/kg and 749 W/kg at 1 A/g energy and power density. Furthermore, two Cu 2 FeSnS 4 /PVP/rGO//AC asymmetric devices connected in series for illuminating a commercial red LED more than 1 min were explored. This work focuses the potential use of transition-metal chalcogenide composite and introduces a new material for designing high-performance supercapacitor applications.

“…The SnO 2 peak intensity increases in sample TiO 2 _SnO 2 (1:2) where the SnO 2 ratio is higher. Moreover, the shape of the SnO 2 peaks is different compared with ZnO_SnO 2 samples that may suggest changes of the crystallite sizes [ 57 , 58 ]. The post-deposition thermal treatment used in order to eliminate all the carbonaceous species may also influence the synergy between the metal oxide particles.…”

The photocatalyst materials correlation with the radiation scenario and pollutant molecules can have a significant influence on the overall photocatalytic efficiency. This work aims to outline the significance of optimizing the components mass ratio into a tandem structure in order to increase the photocatalytic activity toward pollutant removal. ZnO_SnO2 and TiO2_SnO2 tandem structures were obtained by the doctor blade technique using different mass ratios between the components. The samples contain metal oxides with crystalline structures and the morphology is influenced by the main component. The photocatalytic activity was tested using three radiation scenarios (UV, UV-Vis, and Vis) and two pollutant molecules (tartrazine and acetamiprid). The results indicate that the photocatalytic activity of the tandem structures is influenced by the radiation wavelength and pollutant molecule. The TiO2_SnO2 exhibit 90% photocatalytic efficiency under UV radiation in the presence of tartrazine, while ZnO_SnO2 exhibit 73% photocatalytic efficiency in the same experimental conditions. The kinetic evaluation indicate that ZnO_SnO2 (2:1) have a higher reaction rate comparing with TiO2_SnO2 (1:2) under UV radiation in the presence of acetamiprid.

In this study, we report the fabrication of binary chalcogenide zinc sulfide (ZnS) quantum dots (QDs) paying a facial, economical, eco-friendly, and template-free chemical method. The as-synthesized nanomaterial has a single cubic phase; based on its structural features, it was confirmed that the nanoparticles are grown as QDs (2-10 nm). Morphological studies display the formation of agglomerated QDs (3 nm). The energy-dispersive spectroscopy shows that the essential elements are in the stoichiometric ratio as in the precursor solutions. Optical properties confirmed that the QDs are suitable for optoelectronic devices revealing room-temperature photoluminescence. The charge-storage electrochemical activity was explored via electrochemical characterization performances. Electrochemical studies show that the synthesized material has charge storage ability. And according to the International Commission on Illumination, the ZnS QDs show green emission, thus presenting that the material will be useful for biological applications. In addition, these nanoparticles exhibit incredible anticancer activities especially against breast cancer cells and may be used for biological or biomedical applications as well.
