Enzyme mimics of spinel-type CoxNi1−xFe2O4 magnetic nanomaterial for eletroctrocatalytic oxidation of hydrogen peroxide

- Spinel-type CoxNi1−xFe2O4 (x = 0, 0.2, 0.4, 0.5, 0.6, 0.8, 1.0) were synthesized.
- CoxNi1−xFe2O4 were first employed as novel enzyme mimic sensing materials of H2O2.
- Co0.5Ni0.5Fe2O4/CPE showed excellent electrocatalytic activity to H2O2.
- Co0.5Ni0.5Fe2O4/CPE was successfully applied to determine H2O2 in toothpastes.
