Abstract: The objective of this study is to develop novel and sustainable corrosion inhibitors, which is an important and challenging task in corrosion management. This study reports the fabrication of a novel nanocomposite (NC) through the functionalization of an iron metal-organic framework (MOF) using cumin-derived carbon dots (CD). The MOF@CD NC was tested as a novel corrosion inhibitor for Q235B steel in 1.0 M HCl solution. The corrosion inhibition potential was significantly improved through the functionalization process and gravimetric tests showed an inhibition efficiency of about 98 % after 72 h immersion at 25 °C with an inhibitor concentration of 100 mg/L. FT-IR and XPS analysis indicated that binding and adsorption were achieved through functional groups of MOF@CD NC. SEM and AFM studies showed significant surface damage reduction and supported the formation of a powerful protective layer in the presence of inhibitor. This research represents a significant step forward in corrosion protection technology by introducing a new class of materials with excellent performance at low concentrations, offering a promising solution for industrial applications. [Display omitted] • The corrosion inhibition behavior of carbon dot modified Fe-MOF was tested. • MOF@CD reduced the dissolution of Q235B steel in acidic media. • Metal/inhibitor interaction was explored through FT-IR/XPS studies. • Protective film formation was explored through AFM/SEM studies.
