Abstract

Corrosion is a global issue, costing the economy more than $2.5 trillion annually and affecting metal structures across various industries. Corrosion inhibitors effectively mitigate metal corrosion and are popular in the field of corrosion protection, due to their efficiency, low cost, and environmentally friendly properties. Carbon dots (CDs), as a new class of carbon nanomaterials, show significant potential as corrosion inhibitors. Currently, various methods have been developed to synthesize efficient CD inhibitors, and the structures of CD inhibitors can be easily regulated by changing the synthetic parameters. More importantly, CDs demonstrate promising inhibition performance in various environments, including acidic solutions, NaCl solutions, CO₂-saturated NaCl solutions, microbial-corroded solutions, and alkaline solutions. Moreover, their related inhibition mechanisms are revealed through electrochemical methods, surface characterization, adsorption isotherms, and theoretical calculations. This review comprehensively summarizes the research progress of CDs as novel corrosion inhibitors, containing the synthesis methods of CD inhibitors, their applications in different solutions, and their corrosion inhibition mechanisms. This review would inspire researchers to tap into the full potential of CDs as novel corrosion inhibitors.

期刊介绍： The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including: • Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.) • Chemical intermediates • Molecules in excited states • Biological molecules • Polymers. The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example: • Infrared spectroscopy (mid, far, near) • Raman spectroscopy and non-linear Raman methods (CARS, etc.) • Electronic absorption spectroscopy • Optical rotatory dispersion and circular dichroism • Fluorescence and phosphorescence techniques • Electron spectroscopies (PES, XPS), EXAFS, etc. • Microwave spectroscopy • Electron diffraction • NMR and ESR spectroscopies • Mössbauer spectroscopy • X-ray crystallography • Charge Density Analyses • Computational Studies (supplementing experimental methods) We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
