Green Synthesis of Iron Oxide-Palladium Nanocomposites by Pepper extract and Its Application in Removing of Colored Pollutants from Water

Abstract

Fe3O4 nanoparticles were synthesized in the presence of pepper extract as a capping agent via a hydrothermal method. Then palladium nanoparticles and Fe3O4-Pd nanocomposites were synthesized with the aid of pepper extract as a reducing agent. Vibrating Sample magnetometer illustrated that Fe3O4 nanoparticles have super paramagnetic behaviour. The photo catalytic behaviour of Fe3O4-Pd nanocomposites was investigated using the degradation of two azo dyes under ultraviolet light irradiation. The results show that nanocomposites have feasible magnetic and photo catalytic properties. The prepared products were characterized by X-ray diffraction pattern, scanning electron microscopy, transmission electron microscopy and Fourier transform infrared spectroscopy.

Green synthesis of iron-based nanomaterials for environmental remediation: A review

“…Mixture of iron (III) chloride hexahydrate and iron (II) sulphate heptahydrate in distilled water serves as the precursor. Dendrite-like Iron oxide/palladium nanocomposites with average particle size of 50 nm have been synthesized from pepper extract and applied for the photocatalytic degradation of dye (Khaghani and Ghanbari, 2017). Fe 3 O 4 -Pd nanocomposites were prepared by reacting K 2 PdCl 4 precursor solution with pepper extract at 160°C.…”

Effect of Incubation Time, CuSO4 and Glucose Concentrations on Biosynthesis of Copper Oxide (CuO) Nanoparticles with Rectangular Shape and Antibacterial Activity: Taguchi Method Approach

“…In return, NPs synthesis through biological techniques specifically applying microorganisms emerged as an eco-friendly, clean and benefit alternative to physicochemical techniques [23]. In recent years, green methods have attained tremendous attention in synthesis of pure or oxide MNPs [24][25][26][27]. However, not real green nature of these methods is a major problem [28].…”

“…Besides, the detection of the concentric diffraction rings at 4.82, 2.93, and 2.51 Å, attributed by the hlk planar of (111), (220), and (311) of Fe 3 O 4 (magnetite) according to the standard JCPDS No. 01-1111 [44,45]. Similarly, in the samples treated with both Fe(NO 3 ) 3 and Ni(NO 3 ) 2 (Figure 7(B)), the concentric diffraction rings of 3.64, 2.23, 1.85, and 1.66 Å were marked, attributing to the hlk planar of (012), (113), (024), and (116) of A-Fe 2 O 3 .…”
