Synthesis and Characterization of Zinc Sulfide-Aluminium -Platinum Nanocomposites Produced by Coprecipitation Method
In this investigation, Zinc Sulfide (ZnS) nanoparticles and nanocomposite powders such as Zinc- Aluminium (ZnS-Al), Zinc- Platinum (ZnS-Pt), and Zinc- Aluminium-Platinum (ZnS-Al-Pt) were fabricated using the co-precipitation method, employing zinc acetate and sodium sulfide as primary materials.

| description | In this investigation, Zinc Sulfide (ZnS) nanoparticles and nanocomposite powders such as Zinc- Aluminium (ZnS-Al), Zinc- Platinum (ZnS-Pt), and Zinc- Aluminium-Platinum (ZnS-Al-Pt) were fabricated using the co-precipitation method, employing zinc acetate and sodium sulfide as primary materials. The proposed composite powders were thoroughly characterized using techniques like Energy-dispersive X-ray Spectroscopy, X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Ultraviolet-Visible (UV-Vis) absorption spectroscopy, and photoluminescence analysis. To investigate the structural characteristics of the nanocomposites XRD was employed, and the Debye-Scherrer equation was applied to calculate their crystallite sizes. SEM examinations provided detailed insights into the morphology of the nanocomposites. The optical properties were assessed through UV spectroscopy, which showed that the ZnS nanocomposites displayed a prominent absorption peak in the 295-300 nm range, with the highest absorption at 299 nm, and a bandgap energy of 3.75 eV. This indicates a notable blue shift compared to the spectrum of bulk ZnS. Furthermore, the photoluminescence analysis indicated that the ZnS nanocomposites are capable of emitting light at a wavelength of 400 nm. These findings underscore the significant promise of ZnS nanocomposites and their possible use in supercapacitors as sophisticated electrode materials. |
