Abstract

This study focuses on the synthesis and characterization of a thin film comprising of trimetallic sulphide, Cu2S:ZnS:NiS2. The fabrication process involved the utilization of diethyldithiocarbamate as a sulfur source, employing physical vapor deposition. A range of analytical techniques were employed to elucidate the material’s structure, morphology, and optical characteristics. The thin film exhibited a well-defined crystalline structure with an average crystallite size of 33 nm. X-ray photoelectron spectroscopy provided distinct core level peaks associated with Cu 2p, Zn 2p, Ni 2p, and S 2p. The electrochemical properties were assessed through voltammetry measurements, which demonstrated an impressive specific capacitive of 797 F·g−1. The thin film demonstrated remarkable stability over multiple cycles, establishing it as a highly promising candidate for diverse energy storage applications. In addition, comprehensive investigations were carried out to assess the photocatalytic performance of the fabricated material, particularly its efficacy in the degradation of diverse environmental pollutants. These notable findings emphasize the versatility of trimetal sulphide thin films, expanding their potential beyond energy storage and opening avenues for further research and technological advancements in fields including photocatalysis and beyond.

推动进步:揭示 Cu2S:ZnS:NiS2 三金属硫化物薄膜的巨大潜力
本研究的重点是三金属硫化物(Cu2S:ZnS:NiS2)薄膜的合成和表征。制造过程采用物理气相沉积法,利用二乙基二硫代氨基甲酸乙酯作为硫源。研究人员采用了一系列分析技术来阐明材料的结构、形态和光学特性。薄膜呈现出清晰的晶体结构,平均结晶尺寸为 33 纳米。X 射线光电子能谱提供了与 Cu 2p、Zn 2p、Ni 2p 和 S 2p 相关的明显核心级峰。通过伏安法测量评估了该薄膜的电化学特性,结果显示其比电容高达 797 F-g-1。该薄膜在多次循环中表现出卓越的稳定性,使其成为多种储能应用中极具潜力的候选材料。此外,研究人员还对制备材料的光催化性能进行了全面评估,特别是其在降解各种环境污染物方面的功效。这些引人注目的发现强调了硫化三金属薄膜的多功能性,将其潜力扩展到了能量存储之外,为光催化等领域的进一步研究和技术进步开辟了道路。
