Reactivity at the triple phase boundary underpins both the spatial and temporal non-uniformity of the reacting droplet environment. Crucially, through comparison with experimental data reported in the literature, it is demonstrated that <i>there is no droplet-induced acceleration of the redox catalytic reaction.</i> Reasons for this discrepancy with literature are suggested.

The investigation focuses on the potential-induced changes in the interactions between interfacial acetonitrile molecules and on the onset of reductive acetonitrile decomposition in Li⁺- and Na⁺-containing electrolytes. The acetonitrile molecules exhibit a potential-dependent reorientation, leading to an increase in the concentration of antiparallel dimers at the interface at negative potentials, as the nitrogen end of the molecule is pushed away from the surface. The initial stages of reductive decomposition of acetonitrile are different in the Li⁺- and Na⁺-based electrolytes. Spectral signatures characteristic of amines are seen in LiClO₄ acetonitrile solutions, while amide bands are also observed in NaClO₄. Because traces of water in acetonitrile must be the proton source for the reduction of interfacial acetonitrile to amines and amides, OH⁻ must also be generated during those processes. In fact, ATR-SEIRA spectra reveal the formation and subsequent precipitation of LiOH. Precipitation of NaOH in NaClO₄ seems to be absent, though. With increasingly negative potential, the reductive cleavage of acetonitrile results in the formation of several cyanide species. The corresponding cyanide-characteristic bands show a potential-dependent stretching frequency that suggests they correspond to adsorbed species. These findings highlight the effect of potential-induced solvent reorientation on solvent–solvent interactions at the interface as well as the impact of the electrolyte cation on the products of the reductive decomposition of acetonitrile.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"29 2024","pages":"2213 - 2224"},"PeriodicalIF":2.6,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10008-025-06305-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144125743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When subjected to an electrical stimulus, an electric field is generated between the electrodes, causing solvated ions to migrate through the polymer membrane and create an internal pressure gradient, which results in the composite bending. However, the high cost of noble metals, such as gold and platinum, and the toxic waste generated during deposition are significant drawbacks. This study compares the electromechanical performance of a Nafion®-based IPMC with a reduced platinum (PR-IPMC) layer to that of a reference IPMC (R-IPMC). Tests were conducted under controlled relative humidity (RH), and blocking force and current response were used to assess performance. Scanning electron microscopy (SEM) was employed to examine the morphology of the platinum layer. The devices demonstrated optimal performance at 90% relative humidity (RH), with the PR-IPMC exhibiting a 60% thinner platinum layer. However, it displayed a 40% reduction in blocking force compared to the R-IPMC. The reduced platinum content results in cost savings and reduced waste production while still providing satisfactory mechanical performance. Theoretical analysis using molecular dynamics and finite element method (FEM) simulations revealed the stress distribution (<i>S</i>_Pt) in the platinum layers as a function of their thickness (<i>δ</i>_Pt). Interestingly, <i>S</i>_Pt remained independent of the ionomer’s hydration condition (<i>λ</i>), showing that thinner platinum layers are more efficient at storing stress relative to their thickness. Despite having only 40% of the platinum thickness, the PR-IPMC retained 57.6% of the stress compared to the reference IPMC. This relatively increased stress concentration explains why the decrease in blocking force is less than expected based on the reduction in platinum thickness. FEM simulations, aligned with experimental results, provide a useful tool for predicting device behavior under various conditions and guiding the development of future IPMC devices.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"29 2024","pages":"2407 - 2418"},"PeriodicalIF":2.6,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144125744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These devices have gained increasing attention this century as they have the possibility of valorising otherwise wasted (heat) energy to useful (electrical) energy with no moving parts, no greenhouse gas emissions, and using sustainably sourced elements such as iron (Fe). Liquid thermocells suffer from several issues including electrolyte leakage, lower ‘observed’ temperature gradients than those applied and poor mechanical properties. Towards applications such as body heat harvesting — where thermal energy sources are dynamic — these disadvantages can become significant. Gelled electrolyte thermocells have been developed as these are self-contained systems that achieve higher temperature gradients across the thermocell and have mechanical properties that allow the ability to stretch, bend, and twist. This makes gelled thermocells compatible with many of the proposed applications of these devices. However, compared to liquid electrolyte thermocells, gelled electrolyte thermocells typically achieve significantly lower performance, mainly due to frustrated ion transport in the denser matrix, reducing the generation of current, which also leads to reductions in power output over time. This review provides an overview of the current state of gelled electrolyte thermocells and compares them to their liquid counterparts.</p></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"29 2024","pages":"2055 - 2074"},"PeriodicalIF":2.6,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10008-025-06294-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144125553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
