采用恒电流电沉积结合原电池置换和合成后热退火的方法制备了Pt-CuO纳米复合薄膜。首先，采用恒电流电沉积法制备了Cu-Cu 2 O复合材料，并将其在375 ℃下热处理10 h，制得的CuO电极对葡萄糖具有长期稳定的响应。通过在10 mM PtCl 4溶液中电流置换Cu-CuO 2 O 30 s，然后在375 ℃下退火10 h，获得了Pt-CuO电极对葡萄糖的进一步增强响应。该电极对碱性溶液中的葡萄糖有很好的响应，分析灵敏度为3812 μAmM−1cm−2，检测限为7.5 μM，线性响应范围为0.6 mM。这些结果可以推广到其他贵金属-金属氧化物纳米复合电极的制备。©作者（s）2016.由ECS发布。这是一篇开放获取的文章，根据知识共享署名4.0许可证（CC BY，http：//creativecommons.org/licenses/by/4.0/）的条款分发，该许可证允许在任何媒体上不受限制地重复使用作品，前提是正确引用原始作品。[DOI：10.1149/2.0881605jes]版权所有。
Nanocomposite films of Pt-CuO were synthesized via galvanostatic electrodeposition combined with galvanic replacement and post-synthesis thermal anneal. First, Cu-Cu2O composite was prepared by galvanostatic electrodeposition; heat-treatment of the as-prepared Cu-Cu2O composite at 375◦C for 10 h resulted in a CuO electrode showing response to glucose with long term stability. Further enhanced response to glucose was obtained with a Pt-CuO electrode, which was synthesized by galvanic replacement of Cu-Cu2O in 10 mM PtCl4 solution for 30 s followed by annealing at 375◦C for 10 h. The resulting Pt-CuO electrode showed excellent response to glucose in alkaline solution with an analytical sensitivity of 3812 μAmM−1cm−2, a limit of detection (LOD) of 7.5 μM, and a linear response range to glucose up to 0.6 mM. These results may be extended to the fabrication of other noble metal-metal oxide nanocomposite electrodes for sensor applications. © The Author(s) 2016. Published by ECS.
