Abstract

Adsorption behavior and corrosion inhibition mechanism of imidazole and its C2-halogenated analogues (with the halogen atoms being Cl, Br or I) on Fe(1 0 0) surface were investigated by DFT periodic slab calculations and electrochemical techniques. DFT calculations revealed that C2-halogenated imidazoles adopt the tilted conformation on Fe surface with a significantly lengthened C
