Abstract
Inhibitors have been proven successful and effective in controlling corrosion rates. However, their cost and harmful side effects are bothering them. Hence, natural materials (NMs) are in high demand for many years. NMs are considered a rich source of various active molecules that can build a protective layer to shield metals in corrosive environments. Based on the reported results, the NMs are found to be highly efficient (>95 % in some cases). The reason is adsorption of their phytochemicals on metals and blockage of corrosive molecules to the surface. Theoretical approaches like density functional theory (DFT) calculations and Monte Carlo (MC) as well as molecular dynamics (MD) simulations, are also used for accessing and comparing their performance. To achieve more economic and environment-friendly inhibition, waste natural materials (WNMs) have also been widely investigated. All the investigations advocated that they are very useful and could be a good replacement for synthetic inhibitors for various applications. However, there are some associated challenges, too. Their degradation at high temperatures, the inability of long-term protection, high concentrations in some cases, a reduced life cycle, the need for dedicated purification, efficient synthesis procedures, and more scientific selection are the few major challenges. This review provides a view of the NMs and WNMs that have been used for corrosion protection in various applications in the last twenty years and discusses their utilities, challenges, and future scopes, with additional details based on the analysis.
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.
