Abstract A Nibased rareearth perovskite LaNiTiO3 nanoparticles was synthesized and its catalytic activity was investigated. Based on this, a simple and quick nonenzyme electrochemical sensor was fabricated with stable and reliable performances for the determination of hydrogen peroxide (H2O2). The techniques of Xray diffraction, FTIR spectra, transmission electron microscopy, Xray fluorescene spectroscopy and scan electronmicroscope were used to characterize the composition, structure and morphology of assynthesized sample. The sensor based on this nanomaterial was investigated and optimized by cyclic voltammetry and currenttime techniques. The results showed the working electrode modified with LaNiTiO3 (0.5 g/L, 8.0 μL) in 0.1 mol/L NaOH exhibited good catalytic properties for H2O2. Under the optimum conditions, the sensor performed excellent properties, such as quick response time (about 2 s), a wide linearity (0.2 μmol/L -8.0 mmol/L), a low detection limit of 0.05 μmol/L (S/N=3), a high sensitivity of 957 μA (mmol/L
