Recent advances in polyoxometalates acid-catalyzed organic reactions

A photocatalyst with an enhanced Schottky effect and an efficient electron-transfer channel fabricated by assembling Ni–WC heterojunction nanoparticles on g-C3N4 for highly efficient removal of chlorophenols

“…Chlorophenols (CPs) as one of the most common persistent organic pollutants (POPs) are widely present in the production processes of various industrial materials including petrochemicals, anticorrosive rust, pharmaceuticals, wood preservatives, insecticides, synthetic dyes and so on. 1–3 The irritation caused by CPs to the skin and mucous membrane leads to strong biotoxicity in organisms. 4 Moreover, investigations have demonstrated that CPs have strong anti-degradation ability and are prone to bioaccumulate in human bodies.…”

Interfacial engineering of POM-stabilized Ni quantum dots on porous titanium mesh for high-rate and stable alkaline hydrogen production

“…Polyoxometalates (POMs), a kind of early transition metal oxide cluster with small size (≈1 nm), [27][28][29][30] have been regarded as ideal precursors for the synthesis of electrocatalysts because of their versatile structures, abundant metal sources, precise atomic active sites and chemical modifications. 2 Based on the above advantages, our group has previously fabricated highly efficient HER electrocatalysts with quantum dot structures, 31 as well as ultrathin Ni-doped molybdenum sulfide nanosheet structures based on POM clusters.…”

Polyoxometalate-Intercalated Tremella-Like CoNi-LDH Nanocomposites for Electrocatalytic Nitrite–Ammonia Conversion

“…Polyoxometalates (POMs) are a kind of classic crystalline metal-oxo clusters that can undergo reversible multiple-electron transformations while keeping structural stability. − The unique “electron switch” effect of POMs has made them attractive for many electrocatalytic reactions such as hydrogen evolution, − oxygen reduction, and CO 2 reduction − in recent years. Inspired by the fact that POMs can modulate the electron transfer processes and further improve the activity and selectivity of these electrochemical reactions, we legitimately hypothesize that POMs could be ideal NO 2 RR molecular-based electrocatalysts.…”
