The green synthesis of iron nanoparticles (FeNPs) doped and silver nanoparticles (AgNPs) loaded reduced graphene oxide (rGO) (Fe-Ag@rGO) nanocomposite and its applications in methylene blue (MB), malachite green (MG), rhodamine B (RB) degradation were reported. Initially, AgNPs loaded rGO (Ag@rGO) nanocomposites were synthesised simultaneously by an ecological method using Tamarindus indica shell extract as a green reducing agent. Then, the doping of FeNPs into rGO@Ag nanocomposites afforded Fe-Ag@rGO nanocomposite. Interestingly, the finding of this study confirmed that the Fe-Ag@rGO nanocomposites exhibited countless stupendous features in terms of dye degradation. Briefly, the UV-visible spectroscopy and Fourier-transform infrared spectroscopy (FTIR) study confirmed the synthesis of Fe-Ag@rGO nanocomposite. The scanning electron microscopy (SEM) images showed the spherical shape with cross-linked network structures that confirmed the surface modification and synthesis of Fe-Ag@rGO nanocomposite. Finally, the dye degradation potential of the photocatalyst was found to be 97.20%, 98.43%, and 97.33%, for MB, MG, RB, respectively. Herein, the improved photocatalytic performance of the Fe-Ag@rGO was found due to the larger surface area, porous nature, high electron mobility, and synergistic effect of the Fe-Ag@rGO nanocomposite. Additionally, the effective interfacial hybridisation of ‘Ag’, and doping of ‘Fe’ on the rGO sheet extended the duration of the photogenerated electron (e^-) hole pairs that can also be contributing to dye degradation. Conclusively, the present experiment provides the new Fe-Ag@rGO nanocomposite to the dye degradation, which could be improved environmental remediation.

铁纳米颗粒（FeNPs）掺杂和银纳米颗粒（AgNPs）负载还原氧化石墨烯（rGO）（Fe-Ag@rGO）纳米复合材料的绿色合成及其在亚甲蓝（MB）、孔雀石绿（MG）、罗丹明B中的应用（ RB) 降解的报道。最初，使用罗望子通过生态方法同时合成了负载 AgNPs 的 rGO（Ag@rGO）纳米复合材料壳提取物作为绿色还原剂。然后，将 FeNPs 掺杂到 rGO@Ag 纳米复合材料中，得到 Fe-Ag@rGO 纳米复合材料。有趣的是，这项研究的发现证实了 Fe-Ag@rGO 纳米复合材料在染料降解方面表现出无数惊人的特性。简而言之，紫外-可见光谱和傅里叶变换红外光谱（FTIR）研究证实了 Fe-Ag@rGO 纳米复合材料的合成。扫描电子显微镜 (SEM) 图像显示具有交联网络结构的球形，证实了 Fe-Ag@rGO 纳米复合材料的表面改性和合成。最后，发现光催化剂对 MB、MG、RB 的染料降解潜力分别为 97.20%、98.43% 和 97.33%。在此处，由于 Fe-Ag@rGO 纳米复合材料具有更大的表面积、多孔性、高电子迁移率和协同效应，Fe-Ag@rGO 的光催化性能得到了改善。此外，“Ag”的有效界面杂化和 rGO 片上“Fe”的掺杂延长了光生电子的持续时间（e^- ) 也会导致染料降解的空穴对。最后，本实验为染料降解提供了新的 Fe-Ag@rGO 纳米复合材料，可以改善环境修复。
