Key Points

Synthesize and characterize organic/inorganic hybrid polymers capable of rapid gelation and catalytic degradation of toxic molecules and chemical warfare agent analogues.
Synthesized hybrid polymers by covalently linking 1,3,5-benzenetricarboxamide units to anionic polyoxovanadate clusters paired with varying counter-cations.
Evaluated gelation kinetics upon exposure to polar aprotic organic liquids.
Tested catalytic activity under mild conditions for aerobic thiol oxidation, hydrogen peroxide-assisted sulfide oxidation, and organophosphate hydrolysis.
Polymer materials formed stable gels within seconds upon contact with polar aprotic organic solvents.
The networks effectively catalyzed the aerobic oxidation of malodorous thiols and the peroxide-driven oxidation of toxic sulfides under mild conditions.
The materials facilitated the catalytic hydrolysis of organophosphate chemical warfare agent analogues under mild conditions.

Implication

Experimental study demonstrates rapid gelation and catalytic breakdown of hazardous compounds using hybrid polyoxovanadate networks, highlighting their utility in chemical decontamination.
