Abstract

A major challenge for modern society is securing quality water for various uses. Membrane water treatment will be crucial for drinking water, desalination, and wastewater reuse. The development of bismuth molybdate (Bi2MoO6) nanoparticles has enabled the production of novel Bi2MoO6‐incorporated cellulose acetate (CA) membrane nanocomposite. The synthesized Bi2MoO6/CA nanocomposites are thoroughly examined for their structural, morphological, and photocatalytic characteristics using X‐ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), X‐ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM) with energy dispersive X‐ray spectroscopy (EDX) analysis. The photocatalytic properties are determined by evaluating the degradation of Malachite Green (MG) and Rose Bengal (RB) by the nanocomposite membranes under the illumination of a UV light simulator. Notably, the Bi2MoO6/CA nanocomposite membrane displays exceptional and sustained photocatalytic efficiency (78%) and (84%) in MG and RB dye degradation, respectively. Moreover, the effective loading of the Bi2MoO6 onto the CA membrane enhances electron and hole adsorption while facilitating carrier movement. Furthermore, the stability exhibited by the Bi2MoO6/CA nanocomposite photocatalysts remains impressive even after multiple cycles, demonstrating their durability. This research introduces a cutting‐edge semiconductor‐based hybrid nanocomposite material that proves highly efficient in the photocatalytic degradation of organic dyes, showcasing promising advancements in environmental remediation strategies.

利用 Bi2MoO6/醋酸纤维素光催化膜进行可持续废水处理

现代社会面临的一个重大挑战是确保各种用途的优质水。膜水处理对于饮用水、海水淡化和废水回用至关重要。钼酸铋（Bi2MoO6）纳米粒子的开发使新型 Bi2MoO6 嵌入醋酸纤维素（CA）膜纳米复合材料的生产成为可能。利用 X 射线衍射 (XRD)、傅立叶变换红外光谱 (FTIR)、X 射线光电子能谱 (XPS) 和扫描电子显微镜 (SEM) 以及能量色散 X 射线能谱 (EDX) 分析，对合成的 Bi2MoO6/CA 纳米复合材料的结构、形态和光催化特性进行了深入研究。通过评估纳米复合膜在紫外光模拟器照射下对孔雀石绿（MG）和玫瑰红（RB）的降解情况，确定了纳米复合膜的光催化性能。值得注意的是，Bi2MoO6/CA 纳米复合膜在降解孔雀石绿和玫瑰红染料方面分别表现出了卓越而持久的光催化效率（78%）和（84%）。此外，Bi2MoO6 在 CA 膜上的有效负载增强了对电子和空穴的吸附，同时促进了载流子的移动。此外，即使经过多次循环，Bi2MoO6/CA 纳米复合光催化剂表现出的稳定性仍然令人印象深刻，这证明了它们的耐久性。这项研究介绍了一种基于半导体的尖端混合纳米复合材料，该材料在光催化降解有机染料方面被证明具有很高的效率，在环境修复策略方面展示了广阔的发展前景。
