Abstract: In this work, a novel hydrogen peroxide electrochemical sensor was constructed with ferroferric oxide (Fe3O4) magnetic nanoparticles, which demonstrated good electrocatalytic activity for hydrogen peroxide. There existed a good linear relationship between the concentration of hydrogen peroxide and the oxidation peak current in the range of 1.00 × 10-6 ~ 1.00 × 10-3 mol·L-1 (R = 0.9980) with the detection limit of 6.60 × 10-7 mol·L-1. The sensor exhibited good anti-interference ability, high reproducibility and stability.

Key words: hydrogen peroxide, Fe3O4 nanoparticles, carbon nanoparticles
