Abstract

This study introduces a novel green synthesis method using Hyphaene Thebaica fruit extracts to produce WO₃ nanoflakes. The synthesized material exhibits remarkable visible light photocatalytic efficiency in degrading Methylene Blue (MB) and Congo Red (CR) pollutants. With removal efficiencies exceeding 98% for MB and 93% for CR within short durations, the WO₃ nanoflakes show promise for water treatment. Trapping experiments suggest that hydroxyl radicals, hydrogen peroxide, and holes are the primary reactive species involved in the photodegradation process. Additionally, the recyclability study demonstrates the stability and reusability of WO₃ nanoflakes, further highlighting their potential for practical applications in wastewater treatment.

利用绿色合成的 WO3 纳米片去除阳离子和阴离子染料的环境水处理：光催化研究

本研究介绍了一种新型的绿色合成方法，该方法利用 Hyphaene Thebaica 果实提取物来生产 WO3 纳米片。合成的材料在降解亚甲基蓝（MB）和刚果红（CR）污染物方面具有显著的可见光光催化效率。在短时间内，WO3 纳米片对甲基溴和刚果红的去除率分别超过 98% 和 93%，显示出其在水处理方面的前景。捕集实验表明，羟基自由基、过氧化氢和空穴是参与光降解过程的主要活性物种。此外，可回收性研究证明了 WO3 纳米片的稳定性和可再利用性，进一步凸显了它们在废水处理中的实际应用潜力。
