Abstract

, corresponding to a corrosion inhibition efficiency of 92.66%. BPFC functions as a mixed-type inhibitor, which concurrently inhibits anodic dissolution processes and cathodic hydrogen evolution reactions. Adsorption of BPFC on metallic surfaces follows the Langmuir adsorption isotherm, with physical adsorption mechanisms predominating. Quantum chemical calculations and molecular dynamics simulations reveal the inhibitory mechanism of BPFC, highlighting the role of tertiary amine groups and CO functionalities. These groups provide lone pair electrons for coordination with metal d orbitals, facilitating adsorption on the metal surface and obstructing the interaction between corrosive ions and the metal substrate.
