“…Utilizing natural resources will enable the achievement of both economic and environmental objectives. In several researches, plant extracts have been mentioned as prospective agents to lessen corrosion in different industrial solutions. − As reported previously, the ethanolic extract of (P.cubebaOE) contains levels of Yatein, Cbenin, cubebinone, cubebininolide, Hinokinin and cubebinin, single aldehyde, and α, β-unsaturated ketone. From the Piper cubeba, several phenolic acids and flavonoids have been found and extracted.…”

This work offers a high-performing, environmentally friendly corrosion inhibitor for carbon steel in 1 M sulfamic acid (H 2 NSO 3 H). Potentiodynamic polarization and electrochemical impedance spectroscopy were used to evaluate the anticorrosion properties of Pipper cubeba official extract (P.cubebaOE) for carbon steel in 1 M H 2 NSO 3 H at 25 to 45 °C. At a temperature of 45 °C, the P.cubebaOE reached a maximum corrosion inhibition efficiency of 96%. P.cubebaOE was also subjected to Fourier transform infrared spectroscopy in order to ascertain its primary chemical composition. Additionally, the behavior of P.cubebaOE in terms of corrosion inhibition on carbon steel was examined at the microscopic level using scanning electron microscopy. The findings demonstrate that P.cubebaOE's adsorption type on carbon steel conforms to the Langmuir adsorption isotherm model. Based on the adsorption isotherm model, the free energy was estimated to be approximately −20.0 kJ/mol, suggesting that P.cubebaOE is physically adsorbing on the surface of carbon steel. The results of the density functional theory and molecular dynamics simulations show that P.cubebaOE exhibits excellent inhibition performance on carbon steel in H 2 NSO 3 H solution and are consistent with the electrochemical experimental results. This work offers significant information on the development of environmentally friendly corrosion inhibitors for carbon steel.
