Due to the increasing demand for water, it has become critical to find an innovative solution to supply clean water. Nanomaterials are widely being used for environmental remediation, and, herein, we report a one-step solution by synthesizing a silver-coated magnetic iron oxide (Ag-MIO) nanoparticle-infused hydrogel. Magnetic iron oxide nanomaterials synthesized by the chemical method were characterized using scanning electron microscopy (SEM), powder X-ray diffraction (XRD), and energy-dispersive X-ray spectroscopy. The XRD spectrum elucidated the predominant formation of the hematite phase, and EDX mapping confirmed the formation of Ag-MIO. This novel Ag-MIO-infused hydrogel showed promising potential for sustainable environmental remediation via efficient heavy metal reduction and methylene blue degradation (95%). This hydrogel has also shown potential biological efficacy against pathogenic microorganisms like Escherichia coli.

摘要

Due to the increasing demand for water, it has become critical to find an innovative solution to supply clean water. Nanomaterials are widely being used for environmental remediation, and, herein, we report a one-step solution by synthesizing a silver-coated magnetic iron oxide (Ag-MIO) nanoparticle-infused hydrogel. Magnetic iron oxide nanomaterials synthesized by the chemical method were characterized using scanning electron microscopy (SEM), powder X-ray diffraction (XRD), and energy-dispersive X-ray spectroscopy. The XRD spectrum elucidated the predominant formation of the hematite phase, and EDX mapping confirmed the formation of Ag-MIO. This novel Ag-MIO-infused hydrogel showed promising potential for sustainable environmental remediation via efficient heavy metal reduction and methylene blue degradation (95%). This hydrogel has also shown potential biological efficacy against pathogenic microorganisms like Escherichia coli.
