Fig. 4From: Oscillations of Cerium Oxidation State Driven by Oxygen Diffusion in Colloidal Nanoceria (CeO2 − x )The oscillations of Ce3+ band intensity (\( {I}_{{\mathrm{Ce}}^{3+}} \)) stimulated by oxidant (C = 1.0 mM) in colloidal nanoceria: a after HP addition for 10.0-nm nanoceria; b after PP addition for 10.0-nm nanoceria; c after multiple HP addition for 10.0-nm nanoceria; d after HP addition for different nanoceria samplesBack to article page
