Exploring the Corrosion Inhibition Efficacy of Epoxy Merged Silver Nanoparticle Synthesized Using Garcinia gummi-gutta Leaf Extract Against Mild Steel in an Acidic Medium

Unveiling the corrosion inhibition efficacy and stability of silver nanoparticles synthesized using Anacardium occidentale leaf extract for mild steel in a simulated seawater solution

“…The Nyquist curve displays a characteristic depressed semicircle pattern, and the diameter of the semicircle positively correlates with CLE and CLE-AgNPs, in line with previous research. 6,7 The Bode phase angle also demonstrated that the steel surface and electrolyte only make one contact. One possible explanation for this result is a protective coating of biomolecules from CLE-AgNPs covering the steel's surface.…”

“…23 They all reported improvements in the corrosion inhibition of mild steel. 5,7,23 The literature above clearly demonstrated the potential of using plant extract-synthesized silver nanoparticles as mild steel corrosion inhibitors. However, despite its recent use in various areas, there has been limited research on the use of cashew leaf extract to synthesize AgNPs.…”

“…Eqn (7) illustrates how FeCl 2 and H 2 O combine to produce Cl − , H + , and FeOH. The repassivation process occurred as a result of the reaction of Cl − and H + ions.…”

“…This is due to the ecofriendly, renewable, biodegradable and non-toxic behavior of the sustainable materials that have been used in various sectors such as energy and power, advanced material development, aviation, drug delivery, tissue engineering, automobiles, defense, and corrosion migration. [1][2][3][4][5][6][7] In the area of corrosion migration, the use of sustainable materials such as plant extracts has been a focus of research and development in recent years. This is due to the non-toxic behavior of the plant extracts as compared with the toxic conventional inhibitors for mild steel.…”

“…Recently, researchers have developed silver nanoparticles (AgNPs) using plant extracts as a reducing agent to enhance the corrosion efficacy of plant extracts. Scientists have prepared silver nanoparticles using methods involving Macrolepiota , 5 Garcinia gummi-gutta leaf, 7 and Elaeis guineensis . 23 They all reported improvements in the corrosion inhibition of mild steel.…”
