Recent advances in mono-lacunary Keggin-type polyoxometalate-based crystalline materials: From synthetic strategies, diverse structures to functional applications

Advances in polyoxometalate-based electrochemical sensors in the last three years

“…). 14–21 With the continuous development of synthetic methods, a large number of TM elements (such as Cu II , Fe III , Co II , etc. ), lanthanides (Ln) (such as La III , Ce III/IV , Pr III , Nd III , Sm III , Eu III , etc. )…”

“…and organic ligands (usually those containing coordination-active carboxyl, amidogen or hydroxy groups) have been introduced into the skeletons of POMs. 14–27 This situation undoubtedly contributes to an overwhelming diversity of molecular structures and unique properties, for example, photoluminescence/electroluminescence ability, reversible multi-electron transport capability, catalytic activity, and so on. Therefore, POM-based materials have been extensively utilized in optical devices, electrochemical/optical sensors, energy-related fields, and some other cutting-edge fields.…”

A Palladium-Containing Polyoxotungstate with Anisotropic Proton Conductivity

“…Polyoxometalates are typically formed through the condensation of high-valence transition metal ions from the V or VI main group elements (V V , Nb V , Ta V , Mo VI , and W VI ), which is an important branch of inorganic chemistry . Due to their well-defined single-crystal structures, tunable chemical compositions, and reversible redox activity, POMs have attracted widespread attention in various fields such as catalysis, , sensing, energy storage, medicine, , ion exchange, and proton conductivity, etc. To date, seven classical POM structures have been reported, including Keggin, Dawson, Lindqvist, Anderson, Silverton, Waugh, and Strandberg types. , Heteropolyoxometalates (HPOMs) can serve as inorganic polydentate ligands to further stabilize other metal ions, including transition metal ions, , and even noble metals like palladium (Pd), to construct novel structures .…”
