A novel nonenzymatic hydrogen peroxide sensor based on LaNi0.5Ti0.5O3/CoFe2O4 modified electrode

► The sensor exhibited wider linear range of concentration change and high sensitivity compared with those previously reported. ► A novel electrocatalyst (LaNi0.5Ti0.5O3/CoFe2O4) which overcomes the disadvantages of native enzymes was obtained. ► At the same time, it is expected to overtake expensive Pt nanoparticles in H2O2 determination.
