Citric acid-assisted ultrasmall CeO2 nanoparticles for efficient photocatalytic degradation of glyphosate

Degradation of glyphosate has attracted much attention all over the world, since glyphosate has been demonstrated to affect the human health through the accumulation in food chain. Herein, we use citric acid as capping agent to synthesize highly-stable aqueous dispersions of monodispersed CeO2 nanoparticles (NPs) with ultrasmall controllable size of 2.1–4.8 nm, high surface areas and rich oxygen defects, which were firstly used as photocatalyst...
