Comparison fabrication, identification and avoidance of corrosion potential of M-CuO NPs / S-CuO NPs to suppress corrosion on steel in an acidic solution

Abstract

Abstract Due to its simplicity and eco-friendly, the use of plants to create metal oxide nanoparticles has recently attracted a lot of attention. Consequently, the purpose of this study was to generate CuO NPs utilizing two different techniques, including a synthetic approach and an aqueous extract of Moringa oleifera leaves (M-CuO NPs) (S-CuO NPs). Nanoparticles produced were evaluated by SEM, EDX, TEM and XRD, to considering the creation of CuO NPs and to determine the morphological, elemental constitution and size the sample. The average size 14.95 and 35.73 nm for S-CuO and M-CuO NPs respectively, having potentials for application as inhibitor in corrosion of MS. The inhibition and adsorption properties of prepared M-CuO NPs and S-CuO NPs on MS in 1M HCl were investigated using the wt reduction assessment. The maximal IEof prepared M-CuO NPs and S-CuO NPs was 95.06% and 92.10%, respectively, at 1000 ppm. The IE % improves with greater concentration of the prepared M-CuO NPs and S-CuO NPs. According to the findings, M-CuO NPs are the most effective green potential inhibitor for MS in acidic conditions. It is demonstrated that the Langmuir isotherms are obeyed by the produced CuO NPs and MS substrate.
