“…The CV curves of PMo 12 and PMoV are shown in Figure A. The first couple of redox peaks of PMo 12 (highlighted with blue arrows) is centered at +0.65 V (vs NHE), which is in accordance with previous studies. , These couple of peaks result from a well-accepted reversible two-electron and two-proton redox process: H 3 PMo 12 VI O 40 + 2e – + 2H + ↔ H 5 PMo 10 VI Mo 2 V O 40 . The anodic peak current shows a linear relationship with the square root of the scan rate, indicating the electron release of reduced PMo 12 on the graphite electrode is an ion diffusion-controlled process (Figure S3).…”

The approach using polyoxometalate (POM) as biomass oxidation catalysts and charge carriers in a flow fuel cell (FFC) is of great interest as it can directly convert biomass to electricity. However, the fundamentals, such as POM charge and discharge characteristics, electrode overpotentials, the regeneration of POMs in both cathode and anode cells, have not been understood. Studies focused on these fundamentals are critically important for improving the performance of these fuel cells. Herein, we constructed a POM-mediated biomass redox flow fuel cell (BRFFC) that generated power density as high as 42 mW cm–2 directly from various high-moisture contented raw biomass fuels, such as wheat straw, sugarcane, corn cob, green corn stover, and peanut shells. Different from previous studies, a new design of the flow fuel cell was constructed by inserting a Ag/AgCl reference electrode. This new design is unique because the discharging process, electrode overpotential, and electrochemical kinetics can be investigated in situ, which provides a deeper fundamental understanding of the biomass flow fuel cell. The results indicate that the POM discharging at the cathode electrode rather than the anode plays a key role in the entire flow fuel cell performance. The energy analysis shows that the biomass flow fuel cell used in this study can generate maximum net energy 2.33 MJ (647 Wh) by consuming 1 kg of 59.5% moistured wheat straw.

“…Dadurch können die Verbindungen auch stabile und gut geordnete Filme bilden, beispielsweise gegossene Filme, Langmuir-Blodgett(LB)-Filme [91][92][93][94] oder schichtweise abgeschiedene Filme (Abbildung 22). [22,[95][96][97][98][99] Wegen der Redoxeigenschaften, Farben und Leitfähigkeiten sowie der magnetischen und katalytischen Eigenschaften der Polyoxometallate sind solche Strukturen vielversprechend für Anwendungen auf verschiedenen Gebieten, von der Katalyse bis hin zu elektronischen Funktionseinheiten.…”

Die Polyoxometallate (POM), eine Untergruppe der Metalloxide, bilden vielfältige Molekülcluster, die nicht nur außerordentlich vielfältige physikalische Eigenschaften zeigen, sondern auch dynamische Strukturen mit Abmessungen vom Nanometer‐ bis zum Mikrometermaßstab bilden können. Hier beschreiben wir die neuesten Entwicklungen von der Synthese bis zur Struktur und Funktion von Polyoxometallaten. Wir diskutieren Wege zur Herstellung höchst differenzierter hierarchischer Systeme mit mehreren voneinander unabhängigen Funktionalitäten und geben eine kritische Analyse, aus der auch nichtspezialisierte Leser die wichtigsten Eigenschaften ersehen können. In diesem Zusammenhang schlagen wir auch ein “Periodensystem der Polyoxometallat‐Baueinheiten” vor. Schließlich beleuchten wir einige aktuelle Herausforderungen beim Design funktioneller Systeme auf der Basis von POM‐Baueinheiten und geben einen Ausblick auf mögliche Anwendungen.

Heteropolyacids, their salts and polyoxometalates have been used as catalysts in wide range of organic reactions such as multi components, oxidation, reductions, electrochemical and photochemical reactions. There have been tremendous and continued efforts to modify the catalytic performance of heteropoly acids such as supporting them on MCM, silica gel, etc. In this review, we have attempted to bring some of new applications of heteropolyacids in organic reactions and recent approaches on modifying them, into focus.
