Potential Corrosion Inhibition Properties of Flavone Derivatives on the Cu(111) Surface: A Combined DFT and Monte Carlo Simulation Study.

Since corrosion causes significant harm to the environment and economy, sustainable corrosion inhibitors are essential. This study set out to examine Anti-corrosion ability of a number of closely related polycyclic compounds of flavone derivatives, namely 5,7-dimethoxyflavone (1), 4',5,7-trimethoxyflavone (2), 3',4',5'-trimethoxyflavone (3), 5-hydroxy-3,3',4',7-tetramethoxyflavone (4), tangeretin (5), 3,3',4',5,6,7,8-heptamethoxyflavone (6), 3',5,7-trihydroxy-4',5',6-trimethoxyflavone (7) and 3',4',5,7-tetrahydroxy-3,6,8-trimethoxyflavone (8), using the DFT/B3LYP/6-311 + + G(d, p) basis set. Monte Carlo simulations were used to reveal the adsorption of the investigated compounds on the Cu(111) surface.

Combined DFT and Monte Carlo simulation studies of potential corrosion inhibition properties of coumarin derivatives.

Context: Corrosion, the degradation of materials due to chemical reactions with their environment presents significant challenges both economically and environmentally. It affects various industries, including construction, transportation, and manufacturing, leading to equipment failures, safety hazards, and increased maintenance costs. Coumarin derivatives have shown promise due to their inherent chemical properties and potential for biodegradability.
