CuCo₂O₄ anchored on Cu foam (CuCo₂O₄/CF) with polycrystalline features was fabricated by a mild process based on solvothermal reaction and subsequent calcination in this work. The structure and morphology of the obtained materials were thoroughly characterized by X-ray diffraction, X-ray photoelectron spectroscopy, field-emission scanning electron microscopy, and transmission electron microscopy. According to the above analysis, the morphology of the CuCo₂O₄ was nanosheet arrays. Meanwhile, the CuCo₂O₄ was grown on Cu foam successfully. The CuCo₂O₄/CF displayed good electrochemical properties for glucose detection at a linear range from 0 mM to 1.0 mM. Meanwhile, the detection limit was as low as 1 μM (S/N = 3), and the sensitivity was 20,981 μA·mM·cm. Moreover, the selectivity and the stability were tested with excellent results. This nanomaterial could show great potential application in electrochemical sensors.
采用溶剂热反应和随后的煅烧的温和工艺，制备了具有多晶特征的负载在泡沫铜（CuCo₂O₄/CF）上的 Co 掺杂 CuO（CuCo₂O₄/CF）。通过 X 射线衍射、X 射线光电子能谱、场发射扫描电子显微镜和透射电子显微镜对所得到的材料的结构和形貌进行了彻底的表征。根据上述分析，CuCo₂O₄ 的形态为纳米片阵列。同时，CuCo₂O₄ 成功地生长在泡沫铜上。CuCo₂O₄/CF 在 0 mM 至 1.0 mM 的线性范围内对葡萄糖检测表现出良好的电化学性能。同时，检测限低至 1 μM（S/N = 3），灵敏度为 20,981 μA·mM·cm。此外，还测试了选择性和稳定性，结果非常理想。这种纳米材料在电化学传感器中具有很大的应用潜力。
