This section of the article, authored by Mahmoud A. Ahmed, Sherif Amine, and Ashraf A. Mohamed, reviews current and emerging trends in inorganic, organic, and eco-friendly corrosion inhibitors. The authors provide a comprehensive overview of various physicochemical mechanisms and experimental results supporting the effectiveness of different inhibitors. Key figures and plots are included to illustrate the corrosion inhibition processes, such as SEM images of mild steel in NaCl solutions with and without inhibitors, polarization curves of carbon steel in nitrite solutions, plots of potential-density polarization (PDP) for blank and SDCI solutions, EIS spectra of mild steel with and without PESA-Zn²⁺ inhibitor, and adsorption systems of PTT inhibitor molecules on Fe surfaces. These visual aids help to demonstrate the mechanisms and performance of the inhibitors in preventing corrosion.This section of the article, authored by Mahmoud A. Ahmed, Sherif Amine, and Ashraf A.
