In this study, we report the synthesis of novel electrolytes by introducing polydentate ligands to these known systems, leading to the formation of [DME ⋅ MgCl ⋅ 3THF]⁺ [Ph₄Al]⁻ <b>1</b> and [DG ⋅ MgCl ⋅ 2THF]⁺ [Ph₄Al]⁻ <b>2</b>, [Mg ⋅ 3DME]²⁺ 2[Ph₃AlCl⁻] <b>3</b> and [Mg ⋅ 2DG]²⁺ 2[Ph₃AlCl⁻] <b>4</b>. These firstly discovered compounds were thoroughly characterized using X-ray crystallography and NMR spectroscopy. Our findings reveal that the choice of counter anion plays a pivotal role in the products and mechanism of the dissociation of the bridged [Mg₂(μ-Cl)₃ ⋅ 6THF]⁺ cation upon the addition of polydentate ligands. Specifically, with the [Ph₄Al]⁻ counter anion (precursor <b>A</b>), the dissociation results in a [MgCl]⁺ mono-cation, while with the [Ph₃AlCl]⁻ counter anion (precursor <b>B</b>), a [Mg]²⁺ divalent cation is formed. The resultant MgCl₂ byproduct enhances solubility, expands electrochemical windows, and improves cyclic stability, leading to superior electrochemical performance of the new electrolytes (<b>1</b>, <b>2</b>, <b>3</b>, and <b>4</b>) compared to the original precursors.

The operating principle of RRDEs is that products of the disk electrode reaction – the rate of which may be influenced by rotation – move to the ring by forced convection, where they participate in an additional electrochemical reaction and will thus be detected. In contrast to classical RRDE experiments, where potentiostatic control is applied to at least one of the electrodes, new techniques were developed in the past decade that utilized dynamic potential control of both electrodes at the same time. The method of “dual dynamic voltammetry” (DDV) has since been applied to study the mechanism of electrochemical processes from electrocatalytic reactions involving dissolved species (such as oxygen reduction) to the study of metal corrosion and polymer degradation phenomena.

This macrocyclic compound was applied in the design of electrochemical sensors for the detection of biogenic amines. Biogenic amines (BAs) are organic bases, which can be present in food and can cause several adverse reactions in consumers. The most significant BAs occurring in food are histamine, serotonin, and dopamine. Limited studies have been reported on thin film cucurbituril-modified electrochemical sensors for solution-based studies. An electrochemical sensor for the detection of biogenic amines was developed by immobilizing CB[7] at the surface of a glassy carbon electrode (GCE). Initially, the L-lysine monomer was polymerized at the surface of GCE to introduce amine groups which will then form a peptide bond with CB[7]. Immobilization of CB[7] was performed through the electrodeposition method as well as physisorption with no applied potential to form GCE/PLL/CB[7]. Scanning electron microscopy and atomic force microscopy revealed morphological properties of CB[7] as reported in the literature. The response profile of the GCE/PLL/CB[7] sensor for histamine was studied using CV, SWV, and UV-vis. The linear response was obtained in the range of 1.66×10⁻⁹–8.30×10⁻⁹ M for HI with a sensitivity of 255.22±38.20 uA M⁻¹ cm⁻².

In this work, we combine Ni based material with Ti₃C₂T_x MXene at different loadings (1, 5 and 10 %) to understand the effect of the MXene on the OER activity and stability. Our results show that the amount of MXene not only affects the OER performance, but the materials surface is also altered.

The optimum material in this study for the OER is the NiO_x/1 %Ti₃C₂T_x which can be rationalized by the lower Ti/Ni ratio in the starting materials hence producing less overall surface TiO₂ during OER. Additionally, when the pure NiO_x and the 1 % Ni-Ti₃C₂T_x are compared by operando Raman spectroscopy, the NiO_x/1 %Ti₃C₂T_x exhibits β-NiOOH at lower overpotentials, which is known to be present for efficient OER on Ni materials.</p>","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"12 9","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400656","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905396","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}
