Abstract

Surfactants enjoy an augmented share of hydrophilicity and hydrophobicity and are well-known for their anticorrosive potential. The use of non-toxic surfactants is gaining growing interest because of the scaling demands of green chemistry. Green surfactants have successfully replaced traditional toxic surfactant-based corrosion inhibitors. Recently, many reports described the corrosion inhibition potential of green surfactants. The present article aims to describe the recent advancements in using green surfactants in corrosion mitigation. They create a charge transfer barrier through their adsorption at the interface of the metal and the environment. Their adsorption is well explained by the Langmuir adsorption isotherm. In the adsorbed layer, their hydrophilic polar heads orient toward the metal side and their hydrophobic tails orient toward the solution side. They block the active sites and retard the anodic and cathodic and act as mixed-type inhibitors. Their adsorption and bonding nature are fruitfully supported by surface analyses. They can form mono- or multilayers depending upon the nature of the metal, electrolyte and experimental conditions. The challenges and opportunities of using green surfactants as corrosion inhibitors have also been described.
