Electrochemical and catalytic behaviour of Dawson-type complexes derived from [(1),2,3-P2Mo2W15O61]10− and first transition metal ions

Electron Transfer Behavior of Multi‐Iron Sandwich‐Type Polyoxometalates and Electrocatalytic Reduction Reactions

“…[31,58] The actual cata- in which the Fe-and W-waves or Fe-and Mo-waves merge in an appropriate pH media. [31,56] This strategy is favorable, and the entire catalytic process occurs at the reduction potential of the Fe III center, which is now observed concomitantly with the Mo VI or W VI reduction waves. The same phenomenon is observed here.…”

“…[56] Electrocatalysis A pH 3 medium was selected for the studies on the electrocatalytic reductions of O 2 and H 2 O 2 . The efficiency of the catalytic process is evaluated by an excess parameter γ, which is defined as C°(O 2 )/C°(POM) for dioxygen and C°(H 2 O 2 )/C°(POM) for hydrogen peroxide (C°ϭ concen-tration of the relevant species indicated in parentheses).…”

A journey into the electrochemistry of vanadium compounds

“…Owing to the very high stability of the V(IV)-substituted [(1),2,2,-PMo 2 W 15 O 61 ] 10− complex throughout the whole pH range, the electrocatalytic oxidation of NADH to NAD + was investigated at pH 8 [272], considering that stability domain for efficient use of NADH is above pH 6.8, where fast hydrolysis is avoided.…”

V-Shaped Polyoxotungstoarsenates Incorporating a Prism-Like Hexa Transition-Metals Center: [M6(H2O)2(AsW9O34)2(AsW6O26)]17− (M2+ = Mn2+, Co2+, Zn2+)

“…The electrochemical decomposition of the anion occurred at 0.90 V for Mn III /Mn IV oxidation (data not shown). 22 Quasi-reversible peaks around at 1.04/0.97 V (Fig. 5c) observed for 2 suggest that occurrence of the two-electron redox process 2(Co 17À .…”
