Nanorods assembled 3D microspheres of TiO2/MnO2 were prepared via a simple one-pot hydrothermal approach. The resultant composite material exhibited remarkable electrocatalytic activity for hydrogen peroxide (H2O2) in comparison to each single component. The electrochemical sensor constructed with TiO2/MnO2 exhibited a linear relationship within the range 0.0001–5.6 mmol·L−1 for H2O2. The limit of detection (LOD) and sensitivity for H2O2 were 0.03 µmol·L−1 (S/N = 3) and 316.6 µA (mmol·L−1)−1 cm−2. Moreover, this sensor can be employed to detect trace amount of H2O2 in serum and urine samples successfully, supporting an insight and strategy for a more sensitive electrochemical sensor.
