提出了一种简单、环保的电化学沉积法制备二维CuO纳米片的方法。所制备的二维CuO纳米片具有无毒、高导电性、大的活性比表面积以及禁带宽度为1.2 eV的p型半导体性质等诸多优点。为了利用这些特性，构建了一种灵敏的电化学传感器用于葡萄糖的安培检测。该传感器的灵敏度为2710 μA mm−1 cm−2，线性范围为0.001~1.0 mm，检测下限为0.8 μM(S/N=3)。此外，修饰电极具有较高的选择性和良好的稳定性。该电极优异的电催化性能归功于其较大的活性表面积、独特的结构形态以及二维CuO纳米片的高电导率。
A simple and environmentally‐friendly approach was developed to synthesize 2D CuO nanosheets using electrochemical deposition. The formed 2D CuO nanosheets (NSs) exhibit numerous advantageous properties such as no toxicity, high electrical conductivity, large active surface area, and a p‐type semiconducting nature with a band gap of 1.2 eV. A sensitive electrochemical sensor was constructed for the amperometric detection of glucose to take advantage of these characteristics. The fabricated sensor displayed an excellent sensitivity of 2710 μA mM−1cm−2along with a wide linear range of 0.001–1.0 mM and a lower limit of detection of 0.8 μM (S/N=3). Additionally, the modified electrode possesses high selectivity and good stability. The outstanding electrocatalytic performance of the electrode is attributed to a large active surface area, unique structural morphology, and the high conductivity of the 2D CuO nanosheets.
