Abstract

The Front Cover highlights an immobilization method of four Keggin-type polyoxometalates (POMs) ([H₂W₁₂O₄₀]⁶⁻, [BW₁₂O₄₀]⁵⁻ [SiW₁₂O₄₀]⁴⁻, [PW₁₂O₄₀]³⁻) by using the reaction with an ionic liquid, 1-butyl-3-vinylimidazolium (BVIM) bromide. The reaction yields a hybrid material (BVIM-POM) as a water-insoluble salt. Cross polarization ¹H-³¹P NMR evidenced the presence of BVIM in the structure of (BVIM)₃[PW₁₂O₄₀]. The salt is mixed with carbon powder and Nafion to prepare an ink and casted on glassy carbon electrodes. The electrochemical behavior of immobilized POMs material is preserved while the electrochemical activity for nitrite reduction is measured. Differential electrochemical mass spectrometry (DEMS) shows the formation of NO and N₂O. More information can be found in the Research Article by Laurent Ruhlmann, Vasilica Badets, and co-workers (DOI: 10.1002/cctc.202400226).

封面：凯金多氧金属酸盐和 1-丁基-3-乙烯基咪唑鎓杂化物增强亚硝酸盐电还原（ChemCatChem 21/2024）

封面重点介绍了通过与离子液体 1-丁基-3-乙烯基溴化咪唑(BVIM)反应固定四种 Keggin 型聚氧化金属（POM）（[H2W12O40]6-, [BW12O40]5- [SiW12O40]4-, [PW12O40]3-）的方法。反应生成的混合材料（BVIM-POM）是一种不溶于水的盐。交叉极化 1H-31P NMR 证明了 (BVIM)3[PW12O40] 结构中 BVIM 的存在。该盐与碳粉和 Nafion 混合制备成墨水，并浇铸在玻璃碳电极上。在测量亚硝酸盐还原电化学活性的同时，保留了固定化 POMs 材料的电化学行为。差示电化学质谱法（DEMS）显示了 NO 和 N2O 的形成。更多信息请参阅 Laurent Ruhlmann、Vasilica Badets 及合作者的研究文章（DOI: 10.1002/cctc.202400226）。
