Radical Scavenging and Catalytic Activity of Fe-Cu Bimetallic Nanoparticles Synthesized from Ixora finlaysoniana Extract

Abstract

Iron–copper bimetallic nanoparticles (Fe-Cu BNPs) were prepared via a green synthesis route. Ixora finlaysoniana has been used in this study as a capping and stabilizing agent in the modification of Fe-Cu BNPs. As-synthesized BNPs were characterized using different techniques including UV/Vis spectrophotometry, FTIR, XRD and SEM. A particle size analyzer and SEM studies indicated the particle size to be in the range of 50–200 nm. In addition, degradation of MB dye in an aqueous system and radical-scavenging potential in a DPPH assay were also examined using BNPs. Methylene blue dye degradation in 17 min was monitored with UV/Vis spectrophotometry, which exhibited the efficiency of Fe-Cu BNPs. Bimetallic nanoparticles were also found to be efficient in neutralizing DPPH free radicals. Furthermore, kinetic studies of both dye degradation and radical scavenging potential are reported in this article. Subsequently, Fe-Cu BNPs synthesized via a green and sustainable method can be employed for dye degradation and free radical-scavenging activities.

Antioxidant and Organic Dye Removal Potential of Cu-Ni Bimetallic Nanoparticles Synthesized Using Gazania rigens Extract

“…The antioxidant capacity of the BNPs was studied in terms of their free radical scavenging potential using a 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay [38,39]. Ten milliliters of DPPH (200, 400, and 600 ppm) were taken in three separate flasks and 90 mL of distilled water was added.…”

“…The transmittance at 3095.27 cm −1 appeared to be due to the presence of the hydroxyl group and C-H group stretching present in beta-amyrin and cholesterol in the gazania extract [43]; the value at 1662.63 cm −1 is due to N-H bending by alkaloids containing amino groups also present in the gazania extract. Additionally, carboxylic acid (-COOH), existing on the boundaries of Cu-Ni BNPs, displays a peak at 859.15 cm −1 ; the peak at 1054.51 cm −1 indicates the C-O-C attached to BNPs [39], while the peak appearing at 602.95 cm −1 is possibly associated with metal-carbon linkage [44].…”

Photocatalytic and Biological Activity of ZnO Nanoparticles Using Honey

“…In recent years, green synthesis has attained much more attention than chemical synthesis [11]. Various plant extracts have already been employed to prepare ZnO 2 of 13 NPs [12][13][14][15][16][17].…”

Synthesis of Cr doped LiMnPO 4 cathode materials and investigation of their dielectric properties

“…[11][12][13] The electrical properties of nano-crystalline lithium metal phosphate materials depend on the synthesis scheme, annealing atmosphere, concentration, and nature of the dopant. [14][15][16] LiMPO 4 exhibits low electronic conductivity (10 À10 to 10 À9 S cm À1 ) at room temperature and high electrical resistivity. 17,18 Owing to low ionic conductivity and high resistivity LiMPO 4 can be deliberated as an appropriate substitute for application in microwave devices.…”

“…Low dielectric losses of LiMPO 4 materials have presented them as a suitable and prospective candidate in electric field tunable device applications 11‐13 . The electrical properties of nano‐crystalline lithium metal phosphate materials depend on the synthesis scheme, annealing atmosphere, concentration, and nature of the dopant 14‐16 . LiMPO 4 exhibits low electronic conductivity (10 −10 to 10 −9 S cm −1 ) at room temperature and high electrical resistivity 17,18 .…”
