11.1 Introduction

Corrosion-induced destruction of metallic-based structures is one of the most critical problems for a varied range of industries because it leads to a severe decline in investment and loss in production, as well as can cause environmental contamination and human loss. The use of corrosion inhibitors is an extraordinary approach to suppressing or limiting metallic degradation under environmental and service conditions (i.e., aggressive media) [1, 2].

A wide range of organic and inorganic compounds are applied as anti-corrosion agents against metallic dissolution in corrosive media. This relates to their intrinsic molecular structure that contains either heteroatoms (e.g., O, N, and S) or conjugated systems (including multiple bonds and aromatic rings). It is well known that these regions of molecules are the suitable and active sites for electron ...
