Abstract
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 (H2 O2 ) 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 H2 O2 . The limit of detection (LOD) and sensitivity for H2 O2 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 H2 O2 in serum and urine samples successfully, supporting an insight and strategy for a more sensitive electrochemical sensor.Graphical Abstract:
