- •
Four synthetic routes were compared to prepare the nanoceria-based reactive sorbents.
- •
The sorbents prepared by homogeneous hydrolysis destroy efficiently the soman and VX nerve agents.
- •
Toxic organophosphates are converted to less-dangerous products completely within a few minutes.
- •
Surface non-stoichiometry and
OH groups promote the destruction by the SN2 mechanism.
