“…Li's group used a Cu-complex-based POVH material [Cu(Pz)](V 4 O 10 ) as an efficient electrocatalyst toward the oxidation of AA (the electrocatalytic efficiency (CAT) was calculated to be 208.3%). 65 Recently, Peng et al synthesized three Cu-complex-based POVH materials [Cu(pty)(V 2 O 6 )]·H 2 O, [Cu(pty)(V 2 O 6 )] and [Cu(tpy)(V 2 O 6 )] (pty = 4′-(4′′-pyridyl)-2,2′:6′,2′′-terpyridine, tpy = 2,2′:6′,2′′-terpyridine) (Fig. 14a).…”

“…Most of the existing studies reported the incorporation of POVs as a solid into carbon paste electrodes, so that analyses of the reactivity and stability of the POV under electrochemical conditions is challenging [62] . In addition, the studies often targeted facile electrocatalytic processes, for example, the conversion of nitrite, bromate, iodate, or ascorbic acid [127–129] . In contrast, little has been reported on more challenging (proton‐coupled) multielectron reactions for small‐molecule activation (e.g.…”

Molecular vanadium oxides, or polyoxovanadates (POVs), have recently emerged as a new class of molecular energy conversion/storage materials, which combine diverse, chemically tunable redox behavior and reversible multielectron storage capabilities. This Review explores current challenges, major breakthroughs, and future opportunities in the use of POVs for energy conversion and storage. The reactivity, advantages, and limitations of POVs are explored, with a focus on their use in lithium and post‐lithium‐ion batteries, redox‐flow batteries, and light‐driven energy conversion. Finally, emerging themes and new research directions are critically assessed to provide inspiration for how this promising materials class can advance research in sustainable energy technologies.

“…The isolated region E of Figure 5 where there is a low band gap cluster contains polyoxovanadate-based MOFs, some of which have already been investigated for their conductive and electrocatalytic properties (e.g. FEYCOE 135 , XEHYEP 136 ). Similarly, the nearby isolated region F contains molybdenum oxide-based frameworks (e.g.…”

<p>Metal–organic frameworks (MOFs) are a widely investigated class of crystalline solids with tunable structures that make it possible to impart specific chemical functionality tailored for a given application. However, the enormous number of possible MOFs that can be synthesized makes it difficult to determine which materials would be the most promising candidates, especially for applications governed by electronic structure properties that are often computationally demanding to simulate and time-consuming to probe experimentally. Here, we have developed the first publicly available quantum-chemical database for MOFs (the “QMOF database”), which consists of properties derived from density functional theory (DFT) for over 14,000 experimentally synthesized MOFs. Throughout this study, we demonstrate how this new database can be used to identify MOFs with targeted electronic structure properties. As a proof-of-concept, we use the QMOF database to evaluate the performance of several machine learning models for the prediction of DFT-computed band gaps and find that crystal graph convolutional neural networks are capable of achieving superior predictive performance, making it possible to circumvent computationally expensive quantum-chemical calculations. We also show how unsupervised learning methods can aid the discovery of otherwise subtle structure–property relationships using the computational findings in this work. We conclude by highlighting several MOFs with low band gaps, a challenging task given the electronically insulating nature of most MOF structures. The data and predictive models generated in this work, as well as the database of MOF structures, should be highly useful to other researchers interested in the predictive design and discovery of MOFs for the many applications dictated by quantum-chemical phenomena.<br></p>
