Treatment of industrial wastewater is one of the biggest challenges that mankind is facing today to prevent environmental pollution and its associated adverse effects on human health. Environmentalists across the world have given a clarion call for dye degradation, wastewater treatment and their effective management in our surrounding habitats. Despite significant progress in the development of new water treatment technologies, new materials haven't matured enough for large scale industrial applications. Hence, the development of new scalable and sustainable multifunctional materials having the potential to treat wastewater and generate energy is the need of the hour. In this direction, novel 3D-flower shaped KTaO (3D-F-KT) material has been synthesized using areca seed powder as a green fuel. This new material has been successfully applied for the treatment of industrial wastewater contaminated with Rose Bengal. The efficiency of the material was analysed using several parameters like catalytic loading, dye concentration, kinetic and scavenging experiments, photostability, effect of co-existing ions and recyclability. In addition, the material was subjected to optical studies and H generation, making it a highly versatile multifunctional material, exhibiting a degradation efficiency of 94.12% in a short span of 150 min and a photocatalytic H generation efficiency of 374 µmol g through water splitting. With an immense potential, KTaO presents itself as a multifunctional catalyst that can be scaled up for a variety of industrial applications ranging from wastewater treatment to energy generation and storage.
工业废水处理是当今人类面临的最大挑战之一，旨在防止环境污染及其对人类健康的相关负面影响。世界各地的环保主义者都呼吁对染料降解、废水处理及其在周围生境中的有效管理进行研究。尽管在开发新型水处理技术方面取得了重大进展，但新材料还没有成熟到可以大规模应用于工业。因此，开发具有处理废水和产生能源潜力的新型可扩展和可持续多功能材料是当前的需要。在这方面，我们使用槟榔种子粉末作为绿色燃料，合成了新型的 3D 花状 KTaO（3D-F-KT）材料。该新材料已成功应用于处理含有孟加拉玫瑰红的工业废水。通过催化负载、染料浓度、动力学和清除实验、光稳定性、共存离子的影响和可回收性等参数对材料的效率进行了分析。此外，还对材料进行了光学研究和 H 生成，使其成为一种高度通用的多功能材料，在短短 150 分钟内表现出 94.12%的降解效率，通过水分解产生 374 μmol·g 的光催化 H 生成效率。KTaO 具有巨大的潜力，它可以作为一种多功能催化剂，用于各种工业应用，从废水处理到能源的产生和存储。
