Hydroxy phenyl hydrazides and their role as corrosion impeding agent: A detail experimental and theoretical study
Abstract
This study presents synthesis of environmentally benign corrosion inhibitors, hydroxy acetophenone derivative
namely, N′-(1-(2-hydroxyphenyl) ethylidene) acetohydrazide (ATOH), N′-(1-(2-hydroxyphenyl) ethylidene)
benzohydrazide (BZOH), 2-(1-(2-hydroxyphenyl) ethylidene) hydrazine-1-carbothioamide (TSCOH) and N′-
(1-(2-hydroxyphenyl) ethylidene) hydrazinecarbothiohydrazide (TCBOH) and full investigation of their
protecting ability against corrosion of MS in 1 M HCl medium. A variety of electrochemical experimental techniques
viz., electrochemical impedance spectroscopy, and potentiodynamic polarization coupled with different
microscopic techniques viz., scanning electron microscopy, atomic force microscopy, and x-ray photoelectron
spectroscopy were run to evaluate the corrosion resistive behaviour of inhibitors. The surface feature of mild
steel was further analysed by measuring contact angle in different electrolytic solutions. Furthermore, these
wet-chemical experimental outcomes are well complemented from results analysed from ab initio DFT study
andMDsimulation. Furthermore, theMD simulation outcomes helped in visualization of interaction and thereby
adsorption of inhibitors on Fe (110) surface.
