Abstract

With the growing emphasis on green chemistry and sustainability, environmentally friendly corrosion inhibitors have gained significant interest. Amino acids, due to their natural origin and strong interactions with metal surfaces via amino and carboxyl groups, are promising alternatives. They offer superior corrosion inhibition efficiency (90%–95% vs. 70%–85%), higher biodegradability (80%–95% vs. 30%–50%), and cost-effectiveness compared to traditional inhibitors. Additionally, they perform well across a broad pH range (3–11) and at elevated temperatures. This review summarizes recent advances in amino acid-based corrosion inhibitors, highlighting their advantages, limitations, structural modifications, and insights from DFT and molecular simulations.

期刊介绍： The journal includes papers in the following areas: – Simple organic liquids and mixtures – Ionic liquids – Surfactant solutions (including micelles and vesicles) and liquid interfaces – Colloidal solutions and nanoparticles – Thermotropic and lyotropic liquid crystals – Ferrofluids – Water, aqueous solutions and other hydrogen-bonded liquids – Lubricants, polymer solutions and melts – Molten metals and salts – Phase transitions and critical phenomena in liquids and confined fluids – Self assembly in complex liquids.– Biomolecules in solution The emphasis is on the molecular (or microscopic) understanding of particular liquids or liquid systems, especially concerning structure, dynamics and intermolecular forces. The experimental techniques used may include: – Conventional spectroscopy (mid-IR and far-IR, Raman, NMR, etc.) – Non-linear optics and time resolved spectroscopy (psec, fsec, asec, ISRS, etc.) – Light scattering (Rayleigh, Brillouin, PCS, etc.) – Dielectric relaxation – X-ray and neutron scattering and diffraction. Experimental studies, computer simulations (MD or MC) and analytical theory will be considered for publication; papers just reporting experimental results that do not contribute to the understanding of the fundamentals of molecular and ionic liquids will not be accepted. Only papers of a non-routine nature and advancing the field will be considered for publication.
