7819 593 CeO2 TEM The resulting CeO2 nanozymes obtained by a simple solvothermal protocol are in highly morphological uniformity and dispersity (Fig. 1a and S1a) with an average size of 31.1 ±3.9 nm (Fig. 1c). The STEM image (Fig. 1b) shows a flower-like morphology assembled by tiny nanoparticles with an average size of 6.1 ± 1.6 nm.
