Article Synopsis
  • Zinc sulfide quantum dots were combined with yttrium tungstate nanosheets to create ZnS-YWO nanohybrids, which were tested for their ability to degrade dyes (brilliant blue and methyl red) and the drug doxycycline using UV-visible light.
  • These nanohybrids achieved impressive degradation rates of approximately 89.92% for brilliant blue, 80% for methyl red, and 85.51% for doxycycline, demonstrating their effective photocatalytic properties.
  • Additionally, the ZnS-YWO nanohybrids maintained high catalytic activity over multiple uses, with degradation efficiencies remaining above 70% even after five cycles, highlighting their potential for environmental applications in treating organic pollutants.

A simple sol-gel combustion process was employed for the creation of MFeO (M=Ni, Co) nanoparticles. The synthesized nanoparticles, acting as both photocatalysts and gas sensors, were analyzed using various analytical techniques. MFeO (M=Ni, Co) material improved the degradation of methylene blue (MB) under UV-light irradiation, serving as an enhanced electron transport medium.

The present study, reports a facile approach for the synthesis of FeWO/FeS nanocomposites were demonstrated through hydrothermal method. The surface morphology, crystalline structure, chemical composition, optical properties of the prepared samples was analysed by different various technique. The result observed analysis indicates that, the formation of heterojunction by 2:1wt% of FeWO/FeS nanohybrid has the lowest recombination rate of electron-hole pairs and the least electron transfer resistance.

Fabrication of layered triple hydroxides (LTH) is a typical and remarkable approach to produce new functionalities passionately investigated for photocatalytic removal of organic pollutants from industrial wastewater. The hydrothermal method was used to prepare different weight percentages of yttrium (Y) doped NiMgAl LTH. The structural, functional, optical, and morphological properties of the prepared samples were investigated using X-ray diffraction, Fourier transformed-infrared spectroscopy, ultraviolet-visible diffuse reflectance spectroscopy, and scanning electron microscopy.
