Abstract

Corrosion inhibition in severe acidic environments remains a significant challenge for industrial applications. Here, we introduce the Unified Interfacial Reaction Coefficient (

U_{IRC}

), a novel parameter designed to capture the complex synergistic effects of Tobacco Stem Extract (TSE)/KI in H₂SO₄ media.

U_{IRC}

offers a unified framework by integrating key electrochemical parameters such as charge transfer resistance and double-layer capacitance, providing a deeper understanding of the interfacial reactions. Quantum calculations provided additional insights into the molecular interactions at the steel interface. This study positions

U_{IRC}

as a robust tool for advancing corrosion science and designing sustainable inhibitors for industrial applications.

期刊介绍： Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies. This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
