Four new dual-functional electro-catalysts formed from small molybdenum clusters and Cu-pyridyl complexes
By changing N-heterocyclic ligands in the same Mo-7/Cu/N-ligand reaction systems, four new organic-inorganic hybrids based on isopolymolybdates, [Cu-2(tpy)(2)(beta -Mo8O26)(0.5)(gamma -Mo8O26)(0.5)]0.25H(2)O (1), [Cu-2(tpy)(2)(H2O)(2)(beta -Mo8O26)] (2), [Cu(bpy)(Mo3O10)]H2O (3), and [Cu(bpy)(H2O)(beta -Mo8O26)(0.5)](0.5) (4) (tpy = 2,2 ‘ :6 ‘ ,2 ‘ ‘ -terpyridine and bpy = 2,6-bis(pyrazol-1-yl) pyridine), were prepared using hydrothermal methods at different pH values. X-ray structural analysis shows that compound 1 has a 1D {-beta-[Mo8O26]-Cu-2-gamma-[Mo8O26]}(n) straight chain structure with mixed beta-[Mo8O26] and gamma-[Mo8O26] polyoxoanions; compound 2 possesses a 3D supramolecular structure based on [Cu(tpy)](2+) motifs and beta-[Mo8O26] clusters; and compound 3 has a 1D chain structure built from [Cu(bpy)](2+) and [Mo3O10](2-) units. In compound 4, [beta -Mo8O26] clusters are linked by [Cu(bpy)](2+) motifs to give rise to a 2D sheet structure including {(beta -Mo8O26)(4)Cu-4} 8-membered rings. Cyclic voltammograms of compounds 1-4 display discrepant dual-functional electro-catalytic activities toward the reduction of nitrite and the oxidation of ascorbic acid in acidic solution. Electrocatalytic tests indicate that the [Mo3O10](2-)-based organic-inorganic hybrid exhibits better electro-catalytic performances than [Mo8O26](4-)-type hybrids towards oxidation and reduction.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 6969-71-7 help many people in the next few years. SDS of cas: 6969-71-7.
