Effect of pH on antioxidant properties of ablated CeO2 nanoparticles in photocatalytic process

[Display omitted] The physicochemical properties of ablated cerium dioxide nanoparticles have been studied in the photocatalytic degradation of methylene blue in the presence of a ZnO nanocatalyst. It was shown that in the photocatalytic process, CeO2 nanoparticles exhibit good antioxidant properties due to an increased content of structural defects in the surface atomic layers of ablated nanoparticles. It was found that the antioxidant activity of the particles increases with a growth of the pH of the aqueous solution.
