In situ generation of H2O2 using CaO2 as peroxide storage depot for haloperoxidase mimicry with surface-tailored Bi-doped mesoporous CeO2 nanozymes

A CaO 2 peroxide reservoir in polyether sulfone and poly(vinylidene fluoride) polymer beads enables the haloperoxidase reaction of Bi 0.2 Ce 0.8 O 1.9 enzyme mimics without external addition of H 2 O 2 .
