Abstract

We demonstrate that the Ce reactivity of CeO2 towards H2O2 is dictated by its local structure and electron density. More than 2400% increase in peroxidase-like activity has been achieved on the (100) surface for glucose detection due to the promoted H2O2 adsorption and subsequent activation by the electron-rich Ce species.
