This study proposed and verified a new strategy of synergistically combining onion peel extract (OPE) and potassium iodide (KI) to enhance the corrosion resistance of Q235 carbon steel. Using electrochemical tests and the weight loss method, the corrosion inhibition performance of the compound in a 1.0 mol L<small>⁻¹</small> NH<small>₂</small>SO<small>₃</small>H solution was evaluated. The weight loss method shows that the synergistic parameter <em>S</em> is always greater than 1, confirming that there is a synergistic effect between the two. The electrochemical polarization curve indicated that OPE, KI, and the combined system were all mixed-type corrosion inhibitors, mainly inhibiting at the cathode. Fourier transform infrared spectroscopy (FTIR) and liquid chromatography–mass spectrometry (LC-MS) were used to analyze the composition of OPE, identifying myricetin (MYR), caffeic acid (CAF), and quercetin (QUE) as the effective active components for corrosion inhibition. X-ray photoelectron spectroscopy (XPS) characterization confirmed that the active components of OPE and KI effectively adsorbed on the surface of carbon steel, forming a dense and stable protective interface film. Combined with density functional theory (DFT) calculations and molecular dynamics (MD) simulations at the molecular level, the mechanism was elucidated. DFT identified the active adsorption centers of myricetin (MYR), caffeic acid (CAF), and quercetin (QUE) in OPE. MD simulations showed that these molecules could hinder the diffusion of corrosive ions such as NH<small>₂</small>SO<small>₃</small><small>⁻</small> and H<small>₃</small>O<small>⁺</small> to the substrate. This study breaks through the limitations of traditional synthesis and opens up a new path for plant-based green corrosion inhibitors.

The structures of MOFs have been optimized <em>via</em> a crystallinity reduction and sulfonate ligand modification method to improve the proton conductivity. Benzenesulfonic acid (-BSA), <em>p</em>-aminobenzene sulfonic acid (-<em>p</em>ASA), and <em>p</em>-sulfobenzoic acid (-<em>p</em>SA) were used for doping in the UiO-66 reaction system. A series of UiO-66-modified target products (UiO-66-X) and the corresponding metal organic gel products (MOG-UiO-66-X; X = -BSA, -<em>p</em>ASA or -<em>p</em>SA), were obtained. The proton conductivity was investigated at four different relative humidities (100%, 75%, 50%, and 30%) from 303 K to 353 K. The results showed that MOG-UiO-66-<em>p</em>ASA had the maximum <em>σ</em> value of 9.38 × 10<small>⁻²</small> S cm<small>⁻¹</small> at 100% RH and 353 K, 358 times higher than UiO-66, which may be related to the reduced crystallinity and the –SO<small>₃</small>H/–NH<small>₂</small> acid–base pairs in the structure from the doped modifying ligand -<em>p</em>ASA. The structural attraction and repulsion effects of acids and bases on protons accelerate the transport speeds of protons in the MOG structure, thereby increasing the proton conductivity of the materials. In addition, proton-transfer mechanism studies reveal that the structural responses of the materials to variations in ambient temperature and humidity are reflected in their activation energies, prompting a transition between the Grotthuss (proton hopping) mechanism and the vehicle mechanism. This mechanistic shift ultimately influences the resulting proton conduction performance. This investigation not only proposes a simple crystallinity-reduction strategy and ligand substitution model for MOF modifications to achieve superior proton conductivity but also provides valuable insights into the adaptation mechanism between proton conduction and environmental conditions. It further offers guidance for the performance optimization of proton-conductive materials. The findings lay research foundations for the performance optimization of proton exchange membranes and the enhancement of their environmental durability in proton exchange membrane fuel cells.
