Abstract
- Iron oxide nanoparticles (Fe <subscript>2</subscript> O <subscript>3</subscript> NPs) are an interested and attractive area of research as they have numerous effective environmental and biomedical applications. Herein we have reported a simple and eco-benign synthesis Fe <subscript>2</subscript> O <subscript>3</subscript> NPs using Tamarix aphylla extract. The extract of the Tamarix aphylla acts both as a reducing and capping agent which leads to the fast and successful eco-benign synthesis of Fe <subscript>2</subscript> O <subscript>3</subscript> NPs.UV/Vis spectroscopy, XRD, EDX, SEM and TEM techniques were used to characterize and explore different features of Fe <subscript>2</subscript> O <subscript>3</subscript> NPs. UV/Vis studies showed asharppeak at 390 nm due to surface plasmon resonance absorption of Fe <subscript>2</subscript> O <subscript>3</subscript> NPs. XRD studies indicated that Fe <subscript>2</subscript> O <subscript>3</subscript> NPs were crystalline in nature. Structural features, elemental composition and geometry of Fe <subscript>2</subscript> O <subscript>3</subscript> NPswere confirmed by SEM, EDX and TEM. The as synthesized Fe <subscript>2</subscript> O <subscript>3</subscript> NPs showed efficient efficacy to degrade 100% of Methylene blue (MB) dye by 4 mg/25 ml MB and revealed 90% scavenging of the more stable DPPH free radical(1 mg/ml). Furthermore, Fe <subscript>2</subscript> O <subscript>3</subscript> NPs showed excellent antimicrobial activity against pathogenic multidrug resistant bacterial strains. The results of the present study explored the potential reducing, capping property of Tamarix aphylla extract, photocatalytic and biomedical applications of eco-benignly synthesized Fe <subscript>2</subscript> O <subscript>3</subscript> NPs which could be an alternative material for effective remediation of lethal organic pollutants and microbes.<br />Competing Interests: Declaration of Competing Interest There is no conflict of interest.<br /> (Copyright © 2020 Elsevier B.V.
