Abstract

Herein, the synthesis and application of an entirely novel ZnIn₂S₄/Co(acac)₂ (ZIS-Co-2) nanocomposite for degradation of hazardous pesticide imidacloprid (IMD) under visible-light irradiation has been investigated. The ZIS-Co-2 nanocomposite demonstrated an outstanding 97.43 ± 1.84 % removal effectiveness against IMD within 60 min of 23 W LED. This improved catalytic performance was attributable to synergistic effects from ZnIn₂S₄ doping, which significantly delayed charge recombination and boosted visible-light absorption, promoting efficient photocatalytic degradation. Furthermore, the degradation of IMD was thoroughly verified using chemical oxygen demand (COD), and the total organic carbon (TOC) removal and breakdown mechanism was elucidated using liquid chromatography-mass spectrometry (LC-MS). Notably, the ZIS-Co-2 nanocomposite revealed outstanding recyclability, preserving catalytic activity for up to six cycles and the ability to degrade other emerging contaminants. Furthermore, neither Co(acac)₂ nor the combination of ZnIn₂S₄ with metal complexes has been previously produced or explored for visible light-active photocatalytic applications, highlighting the originality of our study. Overall, the ZIS-Co-2 nanocomposite is a promising and sustainable solution for efficiently removing IMD and other environmental pollutants, with significant practical implications in wastewater treatment and environmental restoration.

新型 ZnIn2S4/Co(acac)2：一种用于提高水相中吡虫啉去除率的无机-有机杂化纳米复合材料

本文研究了一种全新的 ZnIn2S4/Co(acac)2（ZIS-Co-2）纳米复合材料的合成及其在可见光照射下降解有害农药吡虫啉（IMD）的应用。在 23 W LED 的 60 分钟内，ZIS-Co-2 纳米复合材料对 IMD 的去除率为 97.43 ± 1.84%。催化性能的提高归功于 ZnIn2S4 掺杂的协同效应，它显著延迟了电荷重组并促进了可见光吸收，从而促进了高效的光催化降解。此外，还利用化学需氧量（COD）对 IMD 的降解进行了全面验证，并利用液相色谱-质谱法（LC-MS）阐明了总有机碳（TOC）的去除和分解机制。值得注意的是，ZIS-Co-2 纳米复合材料具有出色的可回收性，可保持催化活性长达六个周期，并能降解其他新出现的污染物。此外，Co(acac)2 和 ZnIn2S4 与金属复合物的组合以前都未被生产或探索用于可见光活性光催化应用，这突出了我们研究的原创性。总之，ZIS-Co-2 纳米复合材料是一种有效去除 IMD 和其他环境污染物的前景广阔的可持续解决方案，在废水处理和环境修复方面具有重要的实际意义。

期刊介绍： Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
