“…The introduction of IDHA raised the corrosion potential of Zn metal and decreased the corrosion current density from 180 to 45 μA cm −2 , indicating a notable inhibitory effect of IDHA on the corrosion process. 41,42 As a result of the inhibition of the HER, the pH at the interface remains stable, thereby partly suppressing the formation of by-products such as Zn 4 SO 4 (OH) 6 · x H 2 O. This inference is corroborated by X-ray diffraction (XRD) tests conducted after immersing zinc foil in different electrolytes for 72 hours (Fig.…”

“…The 1 H NMR (400 MHz, DMSO-d 6 ) spectrum is depicted in the figure, with an integral ratio of δ 3.41 (s, 1 H) to δ 2.03 (s, 1 H) protons at 1:1. The 19 F NMR (376 MHz, DMSO-d 6 ) spectrum showed an integral of δ-148.62 (d, J = 20.4 Hz) proton at 1. The presence of DMSO solvent and residual water was also confirmed at dw2.49 and dw3.33, respectively.…”
