The physical characterizations of the Co3O4 nanoflakes film were performed by scanning electron microscopy (SEM), X-ray diffraction (XRD) and transmission electron microscopy (TEM) technologies, and the electrochemical activity was measured by cyclic voltammetry (CV). As a promising material for electrochemical sensing, the as-synthesized ultrathin Co3O4 nanoflakes film material exhibited excellent electrochemical activity for H2O2 with a wide linear detection range （0 ~ 4 mmol？L-1） and high sensitive current response (~ 1.15 mA？cm-2)
