摘要 本文以电沉积的金属钴薄膜作为原材料，通过简单的氧化技术获得了薄膜前驱体材料，并进一步在350 oC热处理条件下获得了超薄Co3O4纳米片薄膜材料. 通过扫描电镜（SEM），X-射线衍射（XRD），透射电镜（TEM）等手段对材料的物理结构进行了深入分析，并通过循环伏安法（CV）表征了该薄膜材料的电化学活性. 作为电化学传感器件的活性材料，该薄膜材料对H2O2的检测表现出较宽的线性浓度检测范围（0 ~ 4 mmol？L-1）和较高的电流响应(~ 1.15 mA？cm-2)，在该领域具有较高的应用价值.
Ultrathin cobalt oxide (Co3O4 ) nanoflakes film material was synthesized by using an electro-deposited cobalt layer as a raw material through a simple oxidation method and followed by a heat treatment at 350 oC. 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)
