Abstract

We introduce a novel, rapid, and environmentally friendly method for synthesising reduced graphene oxide (rGO)/ZnO nanocomposite. This single-step synthesis involves the pyrolytic decomposition of sucrose to produce rGO, simultaneously with zinc acetate to produce the rGO/ZnO nanocomposite. Unlike conventional methods, this approach is distinguished by its environmental sustainability, avoiding the use of toxic chemicals and generating no harmful byproducts. This method advances the development of sustainable technologies by providing a green alternative for the cost-effective production of rGO/ZnO composites from inexpensive precursors. The process enables bulk production within minutes, making it suitable for industrial-scale applications. Various characterisation techniques confirmed the successful formation of rGO and rGO/ZnO nanocomposites. The materials were then evaluated for their efficacy as a comprehensive water purification solution, demonstrating effectiveness in heavy metal removal, photodegradation of organic pollutants, and bacterial disinfection.

一种新型简便的氧化石墨烯/氧化锌纳米复合材料的合成及其在水处理中的广泛应用

我们介绍了一种新颖、快速、环保的方法来合成还原氧化石墨烯(rGO)/ZnO纳米复合材料。这种单步合成包括蔗糖热解分解生成还原氧化石墨烯，同时与醋酸锌合成还原氧化石墨烯/氧化锌纳米复合材料。与传统方法不同，这种方法的特点是环境可持续性，避免使用有毒化学品，不产生有害副产品。该方法通过提供一种绿色替代方案，以廉价的前驱物为原料，经济高效地生产氧化石墨烯/氧化锌复合材料，从而推动了可持续技术的发展。该工艺可在几分钟内实现批量生产，适用于工业规模应用。各种表征技术证实了还原氧化石墨烯和还原氧化石墨烯/氧化锌纳米复合材料的成功形成。然后对这些材料作为综合水净化溶液的功效进行了评估，证明了它们在重金属去除、有机污染物光降解和细菌消毒方面的有效性。
