A new dimeric isopolyoxoniobate {β-H4Nb52O150} decorated with copper(II)-ethylenediamine for hydrolytic decomposition of chemical warfare agent simulant DMMP

Two high-nuclearity isopolyoxoniobates containing {Nb54 O151}-based helical nanotubes for the decomposition of chemical warfare agent simulants

“…There are novel {Nb 54 O 151 } cluster fragments in compounds 1 and 2 . Unlike the isolated {α-Nb 52 } 21 and {β-Nb 52 } 22 reported by us, the {Nb 54 O 151 } motif exhibits a new type of IPONb, which is first observed in PONb chemistry. As shown in Fig.…”

“…S13 and S14 ESI†). Obviously, the hydrolytic reactivity is a little weaker than that of Nb 47 , 23 but better than that of {β-Nb 52 } 22 and many reported PONbs. 33 The powder collected from the catalytic reaction for the FT-IR spectra shows that it is in agreement with that of the original sample (Fig.…”

“…The {Nb 27 } contains three unprecedented pentagonal {Nb 5 } units, which can be further aggregated into large clusters. Our groups have discovered a series of high-nuclearity isopolyniobates {Nb 52 }, {Nb 81 } and {Nb 114 } based on a {Nb 27 } subunit 21,22 and novel {Nb 47 } unit, as well as its hexamer {Nb 288 }. 23 Besides, the {Nb 26 } subunit in {Nb 52 } was derived from the {Nb 27 } cluster by removing one Nb atom.…”

An organic–inorganic hybrid polyoxoniobate decorated by a Co(iii)-amine complex for electrocatalytic urea splitting

“…26 Furthermore, the [Nb 6 O 19 ] 8− cluster plays a crucial role in dispersing TMorganic complexes, which can ultimately form stable organicinorganic hybrid TM-PONbs. 27 It is well known that the catalytic activity of clusters is highly susceptible to their low stability in water or under reaction conditions. 28 Due to their strong adhesion to the electrode surface, the bubbles produced during the gas reaction tend to accelerate the detachment of active chemicals from the electrode surface, making it difficult to achieve high catalytic activity.…”

Surface Acoustic Wave DMMP Gas Sensor with a Porous Graphene/PVDF Molecularly Imprinted Sensing Membrane

“…Almost all studies examine simulants, which have no toxicity or less toxicity, but similar functional groups, structures and properties as nerve gases. DMMP [ 3 , 4 ] is a well-known nerve agent simulator, specifically of Sarin.…”
