Electrocatalyst materials for fuel cells based on the polyoxometalates [PMo(12−n)VnO40](3+n)− (n = 0–3)

Enhanced activity of molybdovanadophosphoric acid modified Pt electrode for the electrooxidation of methanol

“…The curves shape was consistent with the previous reports [34]. Compared to PMA, an obvious reduction peak appeared at about 0.15 V in the PMVs, as shown in the rectangle, which corresponded to the V 3+ /V 4+ couple [35]. hydrogen adsorption/desorption region, an evident oxidation and reduction peak was attributed to the adsorption of HPA which ensured the adsorption of HPAs [21,34].…”

Dissolved oxygen amperometric sensor based on layer-by-layer assembly using host–guest supramolecular interactions

“…Several electron transfer mediators have been used to shuttle electrons between oxygen and the electrode surface. Electrodes modified with bilirubin oxidase [5], palladium [6], iron 2,6-bis(imino)-pyridyl complexes [7], cobalt(II) porphyrin complexes [8], phenathrenequinone [9], hemin [10], Pt on a nafionbonded carbon electrode [11], ruthenium [12], polyoxometalates [13], phenanthroline [14] and phthalocyanines [15] have been used in the study of oxygen reduction. Among them, the porphyrins have acquired considerable interest due to their singular properties, including high thermal stability and catalytic efficiency for a great number of molecules.…”

Preparation and characterization of Ce- and La-doped Ba2In2O5 as candidates for intermediate temperature (100–500°C) solid proton conductors

“…In recent years, more intense research has taken place to develop intermediate temperature fuel cells (100-500 • C) since they combine the advantages of both high and low temperature fuel cells [1][2][3][4][5][6][7][8]. One of the major approaches to achieve this goal involves searching for new electrolyte materials with a sufficiently high ionic conductivity in that temperature range.…”
