Ultrafine platinum nanoparticles are grown on a 3D graphene framework (GF-Pt) via a hydrothermal method. The material, when placed on a glassy carbon electrode (GCE), displays enhanced electrocatalytic activity towards glucose oxidation. This is assumed to be the result of the numerous easily accessible active sites, an enlarged electrochemically active area, and the presence of multiple electron/ion transport channels. The modified GCE can be operated at a low potential (- 0.15 V vs. Ag/AgCl) has linear responses in the 0.1 μM - 0.01 mM and 0.01 mM - 20 mM glucose concentration range, and a 30 nM detection limit. It was applied to the rapid determination of glucose in human serum samples. Graphical abstract Schematic presentation of a glassy carbon electrode modified with ultrafine Pt nanoparticles grown on a graphene framework (GFs-Pt). GFs-Pt presents enhanced electrocatalytic activity towards glucose oxidation. GFs-Pt is used in a sensitive non-enzymatic amperometric glucose sensor.
通过水热法在 3D 石墨烯骨架（GF-Pt）上生长超细铂纳米粒子。将该材料置于玻璃碳电极（GCE）上，对葡萄糖氧化表现出增强的电催化活性。这被认为是由于存在大量易于接近的活性位点、增大的电化学活性面积以及存在多个电子/离子传输通道。修饰后的 GCE 可以在低电位（-0.15 V 对 Ag/AgCl）下工作，在 0.1 μM-0.01 mM 和 0.01 mM-20 mM 葡萄糖浓度范围内具有线性响应，检测限为 30 nM。它被应用于人血清样品中葡萄糖的快速测定。 图表摘要 用生长在石墨烯骨架（GFs-Pt）上的超细 Pt 纳米粒子修饰的玻璃碳电极的示意图。GFs-Pt 对葡萄糖氧化表现出增强的电催化活性。GFs-Pt 用于灵敏的非酶安培葡萄糖传感器。
