Front Cover: Nitrite Electroreduction Enhanced by Hybrid Compounds of Keggin Polyoxometalates and 1-Butyl-3-Vinylimidazolium (ChemCatChem 21/2024)
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).
