Preparation, characterization of green synthesis FeO nanoparticles and their photocatalytic activity towards Basic Fuschin dye

Abstract

In the current study, a green and facile route for the synthesis of iron oxide nanoparticles (FeO-NPs) was adopted. The FeO-NPs were fabricated via a single step green route using aqueous leaf extract of Aegle marmelos (A. marmelos) as capping/reducing and stabilizing agents.The active phytochemicals present in the A. marmelos extract was reduced and stabilized the metal ions to FeO-NPs. This product was analyzed by FTIR spectral studies. Magnetic FeO-NPs surface morphology and particles sizes were determined by HRTEM to reveals spherical shapes with average diameter 18.78 nm. The instrumentally confirmed FeO-NPs were determining the antimicrobial activity against the pathogenic strains of the bacteria Streptococcus Sp and the fungus Candida Sp. The results of the microbial investigation show that when the concentration of synthesized FeO-NPs increase with the increases the activity. The antioxidant properties of synthesized FeO-NPs were evaluated by the DPPH assay. The FeO-NPs displayed a dose-dependent cytotoxicity property against breast carcinoma MDA-MB-231 cells, and the value of IC50 was found to be 304 μg/mL. The obtained FeO-NPs were used as photocatalyst in the degradation/reduction of environmentally polluted organic wastewater dyes. After 20 min of solar light irradiation shows 97 % of degradation efficiency was achieved with 1 mL of FeO-NPs. It is observed all the results, the green synthesized FeO-NPs could be effectively materials and used in several fields like industrial, agricultural, medical, food safety, and dye waste applications.
