Novel CuO thin films composed of porous nanosheets were in situ formed on indium tin oxide (ITO) by a simple, low temperature solution method, and used as working electrodes to construct nonenzymatic glucose sensor after calcinations. Cyclic voltammetry revealed that the CuO/ITO electrode calcinated at 200 °C exhibited better electrocatalytic activity for glucose. For the amperometric glucose detection, such prepared electrode showed low operating potential of 0.35 V and high sensitivity of 2272.64 μA mM −1 cm −2 . Moreover, the CuO/ITO electrode also showed good stability, reproducibility and high anti‐interference ability. Thus, it is a promising material for the development of non‐enzymatic glucose sensors.
