This work reports the green synthesis of a Cu/MgO nanocomposite using Cassytha filiformis L. extract as a reducing agent without stabilizers or surfactants. The immobilization of Cu NPs was confirmed by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM) and energy dispersive X-ray spectroscopy (EDS). The Cu/MgO nanocomposite acts as a heterogeneous and recyclable catalyst for the reduction of 4-nitrophenol (4-NP), 2,4-dinitrophenylhydrazine (2,4-DNPH), methylene blue (MB) and congo red (CR) using sodium borohydride in aqueous media at room temperature. The catalyst was recycled multiple times without any significant loss of its catalytic activity.

Cassytha filiformis L.提取物绿色合成Cu/MgO纳米复合材料及其在水介质中还原亚甲基蓝、刚果红和硝基化合物的催化活性研究

这项工作报告了使用Cassytha filiformis L. 提取物作为还原剂而没有稳定剂或表面活性剂的 Cu/MgO 纳米复合材料的绿色合成。通过傅里叶变换红外光谱 (FT-IR)、X 射线衍射 (XRD)、透射电子显微镜 (TEM)、场发射扫描电子显微镜 (FESEM) 和能量色散 X 射线光谱 (EDS) 证实了 Cu NPs 的固定化）。Cu/MgO 纳米复合材料作为一种非均相和可回收催化剂，用于还原 4-硝基苯酚 (4-NP)、2,4-二硝基苯肼 (2,4-DNPH)、亚甲蓝 (MB) 和刚果红 (CR)硼氢化钠在室温下的水性介质中。该催化剂被循环多次，其催化活性没有任何显着损失。
