“…Furthermore, Table 8 provides data regarding thiosemicarbazones inhibitors reported in literature with structural similarities to HBC and HAC, along with their respective inhibition efficiencies. The inhibition efficiency of HBC and HAC against mild steel alloy corrosion was found to be comparable to, and in some instances even superior to, several other inhibitors 24 – 26 . The HBC and HAC inhibitors in this study demonstrated higher efficiency (96.26% and 95.97%) compared to the previously listed organic inhibitors (91.8%, 93.2%, 92.8%, 94.3%, 92.5%, 93.7%, 94.1% and 94.3%).…”

“…Furthermore, Honghong Zhang and colleagues synthesized novel halogen-substituted benzaldehyde thiosemicarbazone derivatives and assessed their efficacy as corrosion inhibitors for mild steel in 1 M HCl. The research demonstrated a direct relationship between concentration and inhibitory effectiveness, reaching a peak of 94.3% at a concentration of 400 × 10 –6 M 26 . Some publications primarily focus on electrochemical assessments, offering only a superficial examination of structural elements.…”

A novel two tri-thiosemicarbazones derivatives, namely 2,2',2''-((2-Hydroxybenzene-1,3,5-triyl)tris(methanylylidene))tris(N-benzylhydrazine-1-carbothioamide) (HBC) and 2,2',2''-((2-hydroxybenzene-1,3,5-triyl) tris (methanylylidene)) tris (N-allylhydrazine-1-carbothioamide) (HAC), have been synthesized and their chemical structures were determined using different spectroscopic and analytical approaches. Then, utilizing methods including open circuit potential, potentiodynamic polarization, and electrochemical impedance spectroscopy, the inhibitory effect of the synthesized thiosemicarbazones on mild steel (MS) in an acidic environment (0.5 M H2SO4) was thoroughly investigated. Remarkably, raising the concentration of our recently synthesized tri-thiosemicarbazones HBC and HAC increased the inhibitory efficiency values. The η values of the two investigated tri-thiosemicarbazones derivatives (HAC and HBC), at each concentration are extremely high, and the maximum values of the efficiencies are 98.5% with HAC and 98.8% with HBC at the 800 ppm. The inhibitors adsorbed on the mild steel surface and generated a charge and mass movement barrier that protected the metal from hostile ions. According to polarization curves, HBC and HAC act as mixed-type inhibitors. Electrochemical impedance testing revealed a notable rise in charge transfer resistance (Rct) readings to 4930-Ω cm2, alongside a reduction in the Constant Phase Element (CPE) value to 5.81 μF, suggesting increased effectiveness in preventing corrosion. Also, density functional theory (DFT) was applied to investigate the assembled tri-thiosemicarbazones HBC and HAC. Moreover, the adsorption mechanism of HBC and HAC on the mild steel surface was explored using Monte Carlo simulation. Finally, the theoretical outputs were discovered to support the practical outcomes.

“…The equivalent circuit utilized for fitting the impedance data is seen in (Figs. 5). The solution resistance and polarization resistance are represented, respectively, by Rs and Rp (which equal the sum of Rct and Rf which represents the resistance of the film created on the metal) and CPE represents the constant phase element.…”

TzPz, a newly synthesized ethyl 2-(3-(3,5-dimethyl-1H-pyrazol1-yl)-H-1,2,4-triazol-1-yl) ethan-ol, was evaluated as a mild steel corrosion inhibitor in 1.0 HCl environment. The synthesis objective for this type of molecule-type was to create a triazole-based molecule with a simple yet effective structure, as well as to increase the number of nitrogen donors to boost adsorption affinities at the metal surface. This investigation began with electrochemical techniques such as EIS & PDP. The results obtained suggest that TzPz is a good inhibitor, with a maximal effectiveness (91.9%) at 303 K. The inhibitory efficacy increases dramatically with increasing concentration and decreases with increasing temperature. According to electrochemical data, TzPz functions as a mixed inhibitor, and the corrosion process is controlled by charge transfer. In addition, the adsorption isotherm adheres to the Langmuir model. UV-visible spectroscopy is used to evaluate the probability of Fe-inhibitory molecule interactions. Theoretical calculations using the DFT technique were performed and discussed for the molecule TzPz in order to understand its interfacial approach and compare them to experimental data.
