Abstract
The motivation behind recreating this chapter is to give a summary of the bibliographical insights expected to make the segment. In the first part, we examine the adsorption of ionic liquids (ILs) as efficient, effective and eco-friendly corrosion inhibitors for various alloys and metals surface in different corrosive media environments and the restraint and coordination chemistry of ionic liquids. The anticorrosive activity of different ILs has been examined with electrochemical techniques followed by weight-loss measurement. The impact of the ILs composition (polar and nonpolar substituents in anions & cations, and alkyl tail length), temperature, concentration, and nature of the medium, which influence the metal corrosion protection, was discussed. In the second part, we examine the interfacial structure and adsorption mechanism of different ILs on the Au (111) surface investigated via quantum chemical calculations.
