Among reported nanozymes, CeO2 seems to be the only transition metal oxide that can mimic phosphatase and peroxidase by catalyzing substrate dephosphorylation and oxidation (with H2O2). However, no consensus on the key Ce species was reached in the literature using spherical CeO2 enclosed by (111) a...
