“…The inhibition mechanism did not alter despite adding inhibitors at various concentrations. Moreover, the interface reaction between the inhibitor solution and metal dominates due to the charge transfer process [49]. This result indicates the formation of coordinate bonding and complex substance in several functional groups shown in the FTIR results.…”

The critical role of newly green corrosion inhibitors shows the disruption of cathodic and anodic reactions at the metals and solution interface. The object of this study is the development of Saga as a corrosion inhibitor to mitigate the effect of corrosive HCl 1M оn mild steel. The inhibitor was extracted using methanol to prepare various concentrations. Fourier transform infrared (FTIR) spectroscopy was used to determine the functional group of the inhibitor. The electrochemical impedance spectroscopy aided by the potentiodynamic polarization was utilized to evaluate the inhibitor’s effectiveness. Optical emission spectroscopy (OES) was implemented to determine the percentage of elements in mild steel. Based on the FTIR results, C=O, -OH, C=C, benzene, and C-O are accountable for the inhibitor to donate its lone pair of an electron to the 3-d orbital of iron metal. Increasing the inhibitor concentration decreases the capacitive double layer to elevate the inhibitor resistance. The higher inhibitor resistance of 29.33 Ω cm-1 increases as the concentration increases due to the depression of Cdl 420.16 µF cm2 at 10 ml inhibitor solution. Parallelly, it increases the inhibition efficiency at 65.58 %, slightly lower than the PP measurement of nearly 88 %. The higher value of adsorption/desorption constant, Kads, at 2.9 L mol-1 shows the strength of the inhibitor, which lowers the value of Gibbs free energy (ΔGads). The Saga inhibitor is considered a chemisorption inhibitor ΔGads –36.87 kJ/mol. The value demonstrates the formation of dative covalent bonding, which promotes the transferred electron from the inhibitor to the substrate. On the other hand, the Saga inhibitor abides by the Langmuir adsorption isotherm as the R2 value is 0.99.

“…A decrease of the FWHM value demonstrates increased crystallinity in carbon structure of homo-CF and grad-CF compared with PRST-CF, indicating the catalytic graphitization function of Co-doping. [24][25][26] The gradiently graphitized structure of grad-CF was further characterized by Raman Mapping, which was performed on the cross-sections of PRST-CF, homo-CF, and grad-CF to acquire ~110 Raman spectra for each sample. The intensity ratios of the 2D band to the G band (I 2D /I G ) were calculated to demonstrate the degree of graphitization in the three CF hosts.…”

Na metal anode (NMA) is one of the most promising candidate materials for next‐generation low‐cost sodium metal batteries. However, the preferred deposition of Na metal at the anode/separator interface increases the risk of dendrite penetration of the separator, consequently, reduces safety and life of batteries with NMA. In this study, a Na deposition‐regulating strategy is shown by designing a gradiently graphitized 3D carbon fiber (CF) framework as host (grad‐CF), whereby Na is guided to deposit preferentially at the bottom of the anode, safely away from the separator. The obtained Na anode significantly reduces the probability of dendrite‐induced short circuits. The grad‐CF host enables NMA stable cycling at a high current density of 6 mA cm−2. When the Na@grad‐CF is applied as anode in full cells pared with Na3V2(PO4)3 (NVP) cathode, it exhibits a reversible capacity of 73 mA h g−1 after 500 cycles with a low decay rate of 0.13%.
