Room-temperature synthesis of nanoceria for degradation of organophosphate pesticides and its regeneration and reuse.

ABSTRACT: A simple low-temperature water-based and one-pot synthesis was developed for the preparation of nanocrystalline CeO₂ that was used for degradation of the toxic organophosphate pesticide parathion methyl. By changing the reaction temperature in the range from 5 °C to 95 °C, several properties (i.e., crystallinity, grain size and surface area) of nanoceria can be easily controlled. The catalytic decomposition of parathion methyl to its degradation product 4-nitrophenol was highly dependent on the CeO₂ preparation temperature. It was demonstrated that at low temperature (i.e. 5 °C), CeO₂ with very small crystallites (<2 nm) and high surface area can be obtained. For practical use, it was demonstrated that highly crystalline CeO₂ can be
