NiZr2S4 bimetallic sulphide thin films: synthesis and multifunctional applications in nanotechnology.

The primary focus of this research is to conduct a comprehensive exploration of the preparation and description of a thin film composed of bimetallic sulphide, NiZr₂S₄. The fabrication process involved the utilisation of diethyldithiocarbamate, employing physical vapour deposition. To gain insights into the material's properties, an array of analytical techniques was employed to investigate its structure, morphology, and optical characteristics. A well-defined crystalline assembly with an approximate crystallite size of 42 nm, corresponding to a crystallinity of 77% was observed. Optical properties were evaluated to determine the material's bandgap energy at 2.7 eV. Through X-ray photoelectron spectroscopy, distinct core level peaks associated with Zr 3d, Ni 2p, and S 2p were identified, providing perceptions into the elemental configuration and chemical bonding of the thin film. Electrochemical properties were assessed through voltammetry measurements, revealing a notable specific capacitive performance of 543 Fg⁻¹. The thin film exhibited remarkable stability over multiple cycles, putting it as a highly auspicious contender for various energy storage devices. Furthermore, extensive investigations were shown to evaluate the photocatalytic capabilities of the fabricated material, explicitly its efficiency in degrading various environmental pollutants. These significant findings underscore the versatility of bimetal sulphide thin films, spreading their potential beyond energy storage and paving the way for further research and technological advancements in areas such as photocatalysis and beyond.
