摘要

半导体锌基纳米材料已成为在废水处理中光催化降解有机污染物的一种有前途的制剂。然而,实现能够直接在水环境中快速生成小型结构的高效合成方案仍具有挑战性。微波辅助合成是一种可行的解决方案,它通过增加压力,从而轻松提高沸点,在水中直接快速地一步生成颗粒。本研究探讨了微波辅助一步合成纯 ZnS 纳米粒子和掺铁 ZnS 纳米粒子的方法,并评估了它们在水悬浮液中光降解喹啉黄(QY)的功效。结果表明,在含有 1%掺铁 ZnS 纳米粒子的情况下,QY 的降解效果非常明显,在 270 分钟后,掺有 500 ppm 掺杂纳米粒子的 QY 降解率约为 66.3%。这些发现凸显了 1%掺铁 ZnS 纳米粒子作为有效纳米催化剂的巨大潜力。

Fast One-Step Microwave-Assisted Synthesis of Iron-Doped ZnS for Photocatalytic Applications
Semiconductor Zn-based nanomaterials have emerged as promising agents for the photocatalytic degradation of organic pollutants in wastewater treatment. However, achieving efficient synthesis protocols capable of rapidly producing small structures directly in aqueous environments remains challenging. Microwave-assisted synthesis presents a viable solution by enabling one-step particle generation swiftly and directly in water through increased pressure, thereby easily elevating the boiling point. This study investigates the microwave-assisted one-step synthesis of pure and iron-doped ZnS nanoparticles and assesses their efficacy in photodegrading Quinoline Yellow (QY) in aqueous suspensions. The results demonstrate a significant degradation of QY in the presence of 1% iron-doped ZnS nanoparticles, achieving approximately 66.3% degradation with 500 ppm of doped nanoparticles after 270 min. These findings highlight the considerable potential of 1% iron-doped ZnS nanoparticles as effective nanocatalysts.

期刊介绍: Crystals (ISSN 2073-4352) is an open access journal that covers all aspects of crystalline material research. Crystals can act as a reference, and as a publication resource, to the community. It publishes reviews, regular research articles, and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on article length. Full experimental details must be provided to enable the results to be reproduced. Crystals provides a  forum for the advancement of our understanding of the nucleation, growth, processing, and characterization of crystalline materials. Their mechanical, chemical, electronic, magnetic, and optical properties, and their diverse applications, are all considered to be of importance.
