Quinoxaline derivatives as eco-friendly corrosion inhibitors for steel and non-ferrous metals: A comprehensive review

Material corrosion is undesirable because it damages building and transportation materials, increases maintenance and replacement costs, and poses a threat to environmental safety. Consequently, tremendous measures are being taken to prevent rusting by employing corrosion prevention strategies. Among these, corrosion inhibitors are the most extensively studied due to their strong inhibitory effectiveness. The structural features of quinoxaline derivatives, including the presence of two nitrogen atoms or functional groups, planar heterocyclic rings, and aromatic and conjugated multiple bonds, have been shown to provide excellent inhibitory performance against the corrosion of steel and other metallic materials in corrosive environments, similar to other organic compounds. This review provides an overview of the recent literature on quinoxaline and its derivatives in mitigating corrosion. This article also includes information on corrosion inhibition mechanisms, corrosion inhibition efficiencies, and the classification of corrosion inhibitors. Additionally, some upcoming directions for corrosion control research in the field of inhibitors are outlined.
