One-step green synthesis and characterization of iron oxide nanoparticles using aqueous leaf extract of Teucrium polium and their catalytic application in dye degradation

Abstract

Green synthesis of materials have received increasing attentions in the field of nanotechnology due to its characteristics of low-cost, high-efficiency, non-toxicity, and eco-friendly manner. In the present study, iron oxide nanoparticles (IONPs) were successfully synthesized using aqueous leaf extract of Teucrium polium as a low-cost and simple green technique to evaluate their effective applicability as dye degradation nanomaterial. The synthesis part comprises the reaction of Fe 3+ to obtain spherical-shaped iron oxide nanoparticles with sizes in the range of 5.68 to 30.29 nm, which were further characterized using various techniques such as transmission electron microscopy (TEM), particle size analysis (PSA), x-ray diffraction pattern (XRD), Fourier transform infrared (FT-IR) spectroscopy, vibrating sample magnetometer (VSM), thermogravimetric analysis (TGA). Additionally, the dye degradation activity of these nanoparticles was studied with the degradation of model dye methyl orange (MO). Remarkably, the results showed that the green synthesized IONPs were able to decolorize MO dye with 73.6% efficiency in a 6-h reaction, and so have the potential to serve as effective catalyst for environmental remediation.

Green synthesis of iron-based nanoparticles using Chlorophytum comosum leaf extract: methyl orange dye degradation and antimicrobial properties

“…Nanoparticles (NPs) can offer more efficient dye degradation owing to their specific physicochemical characteristics such as high surface to volume ratio [5]. So far, a wide variety of NPs including Au [6], CdS [7], TiO 2 [8,9], Manganese-doped ZnO [10], zinc ferrite [11], and iron nanoparticles (INPs) have been successfully used for dye degradation purposes [12]. INPs have been intensively probed for the degradation and removal of organic wastes owing to their versatile properties, high catalytic activities, and highly reactive surface functional groups [13].…”

Remediation of Dyes in Water using Green Synthesized Nanoparticles (NPs)

“…When Beta vulgaris stalks were used, equilibrium reached after 180 minutes for tartrazine and 120 minutes for Bordeaux red. Kouhbanani et al (2019) also reported a successful generation of iron oxide nanoparticles. These nanoparticles were synthesized using aqueous leaf extract of Teucrium polium in size range of 5.68 to 30.29 nm, which was characterized using particle size analysis (PSA).…”

“…Decolorization of methyl dye became possible due to the combination of IONPs and H 2 O 2 . This combination caused the release of free hydroxyl radical (OH•) that attacked and cleaved the azo bond (-N=N-) found in the methyl orange, which led to the decolorization of dye solution (Kouhbanani et al, 2019). Another study of dye decolorization using iron oxide nanoparticles (Fe 2 O 3 NPs) was reported by Bibi et al, in which the nanoparticles were successfully fabricated via green route using pomegranate (Punica granatum) seeds extract, which were confirmed by UV-Vis., XRD, EDX, SEM, and AFM techniques.…”
