Abstract
An electrochemical sensor was promoted for the rapid and efficient detection of hydrogen peroxide via the ZnO nano/microrods-based (GCE) electrode. The ZnO nano/microrods were controllable prepared by changing zinc precursor under hydrothermal condition and the sensing properties of ZnO materials were studied. The sensing performance was optimized by adjusting ZnO’s morphologies and size. The ZnO nanorods (ZNRs)-based electrode exhibits a notable sensing response toward hydrogen peroxide compared to other modified GCE. More importantly, the developed ZNRs-based sensor possesses high sensitivity of 10.8 μA mM−1 and a detection limit (LOD) of 0.28 μM. Thus, the synthesized ZNRs material is proved to be a potential material for the hydrogen peroxide detection in various fields.
