Abstract

Metallic corrosion is a serious issue that is focused by all domains of research scientists all over the world. Exposed metallic surfaces corrode not only in the presence of acidic or alkaline environments but they are also attacked by numerous microbes. Such problems are mostly experienced in petrochemical industries. Inorganic inhibitors, containing heavy metals, are harmful to humans and have a negative impact on the environment, Earth’s surface, and on ground water quality. To eradicate such problems, specialty nanomaterials have come to the fore front. Carbon-based nanomaterials (especially carbon quantum dots) are the most common and feasible alternatives because of their easy manufacturing, non-toxic nature, and low cost. Carbon nanoparticles offer good corrosion inhibition efficiency to various metals in different environments. A stable protective coating formed by the nanoparticles on the metal surface help it to protect the metal surface from corrosion damage. In this chapter, corrosion protection and their mechanistic ways have been elucidated, where carbon nanomaterials are the prime inhibitors. Carbon nanomaterials accelerate the chemical bonding to metal surfaces that, consequently, improve the metallic substrate’s longevity.
