A novel nanocomposites prepared from hollow, octahedral cuprous oxide supported palladium nanoparticles (Cu2O‐PdNPs) through a facile galvanic replacement reaction and carboxylic multi‐walled carbon nanotubes (MWCNTs‐COOH) was modified on the surface of glassy carbon electrode (Cu2O‐PdNPs@MWCNTs‐COOH/GCE) to fabricate a sensor for electrochemical detection of caffeic acid. The synergistic effect between Cu2O‐PdNPs and MWCNTs‐COOH exhibited remarkable electrocatalytic activity, higher selectivity and higher sensitivity toward caffeic acid. At optimized test conditions, the Cu2O‐PdNPs@MWCNTs‐COOH/GCE nanocomposites sensor revealed wider linear range of 0.006‐60 μM with a lower detection limit of 0.002 μM (S/N=3) for caffeic acid determination. Eventually, the proposed nanocomposites sensor was successfully applied to determine the concentration of caffeic acid in red wine samples.

一种基于空心，八面体，Cu2O负载的钯纳米粒子的传感器（通过电流置换反应制备）以及用于电解检测红酒中咖啡酸的羧酸多壁碳纳米管
从空心制备的新的纳米复合材料，八面体的氧化亚铜负载的钯纳米颗粒（铜2 O形PdNPs）通过一个浅显的电置换反应和羧酸多壁碳纳米管（MWCNT-COOH）中的溶液修饰玻碳电极的表面上（铜2 O-PdNPs @ MWCNTs-COOH / GCE）来制造用于电化学检测咖啡酸的传感器。Cu 2 O-PdNPs与MWCNTs-COOH的协同作用表现出了显着的电催化活性，更高的选择性和对咖啡酸的更高敏感性。在优化的测试条件下，Cu 2O-PdNPs @ MWCNTs-COOH / GCE纳米复合材料传感器显示出0.006--60μM的较宽线性范围，而咖啡酸的测定下限为0.002μM（S / N = 3）。最终，提出的纳米复合材料传感器成功应用于确定红酒样品中咖啡酸的浓度。
