FE2O3-DOPED CDO NANOPARTICLE SYNTHESIS AND CHARACTERIZATION FOR ANTIBACTERIAL ACTIVITY

Abstract

Fe(NO3)2 and Cd(NO3)2 were used as precursors in the eco-friendly method to prepare the iron-cadmium oxide (Fe2O3@ CdO) nanoparticles using apple leaves extract. First, combine the two salts in a weight ratio of 1:1. Next, dissolve 1.4 g of the salt mixture in 100 mL of deionized water. The calcination process for the Fe(OH)2-Cd(OH)2 nanoparticles at 550 oC produced Fe2O3@ CdO nanoparticles. XRD, FE-SEM, and TEM methods were used to characterize the nanoparticles. Fe2O3 @ CdO nanoparticles with an average size of 41.73 nm are confirmed to have formed by XRD. While TEM produced heterogonous morphologies, FE-SEM demonstrated that the Fe2O3 @ CdO nanoparticles will produce spherical morphology nanoparticles and significant agglomeration. Gram negative (Escherichia coli and Aeromonas hydrophila) and gram positive (Rhodococcus rhodochrous and Staphylococcus aureus) bacterial strains are evaluated against the produced Fe2O3 @ CdO nanoparticles. The antibacterial activity of the α-Fe2O3 @ CdO nanoparticles is seen to be good (zone of inhibition: E. coli-14 mm).
