The Electrochemical Behavior of Keggin Polyoxometalate Modified by Tricyclic, Aromatic Entity
TL;DR: In this article, the inorganic-organic hybrid polyoxometalates (POMs), (pbpy)4H[PMo12O40(VO)] (1) and(pbpy), (4H4[SiMo 12O40] (2) were synthesized and were used as a solid bulkmodifier to fabricate a three-dimensional bulk-modified carbon paste electrode (CPE) by direct mixing.

Electrocatalytic reduction of nitrite and nitric oxide to ammonia with iron-substituted polyoxotungstates
James E. Toth,Fred C. Anson +1 more
TL;DR: In this paper, it was shown that one of the positions normally occupied by a tungsten cation is occupied instead by an iron cation for the electroreduction of nitrite to ammonia, and that the catalyzed reduction does not produce hydroxylamine as an intermediate and appears to depend upon the ability of the multiply reduced heteropolytungstates to deliver electrons to the NO group bound to the iron center in a concerted multiple-electron step.

TL;DR: In this article, the potential between 0.8 and 0.4 V vs. SCE in the colloidal mixture of WO{sub 3-center dot}2H{sub 2}O/WO[sub 3]-center dot]H {sub 2]-O existing in 2 M H{sub2}SO{sub 4} at 35{degree}C causes the electrodeposition of stable, mixed-valent W(VI,V) oxide aggregates on common electrode substrates.
