【摘要】 金属有机骨架(MOFs)作为一种新型的纳米多孔材料,具有结构可设计性、种类多样性、高比表面积及良好的热稳定性等优点[1],在多个领域显示出潜在的应用前景[2]。本文使用水热法合成一种Cu-MOF/CNTs复合材料,将其用于制备化学修饰电极。结果显示该修饰电极对过氧化氢有良好的电化学催化效果,并且对于过氧化氢的响应具有很好的选择性。当过氧化氢浓度在3×10-6~3×10-2 mol/L之间时,该修饰电极催化过氧化氢的还原峰电流与浓度呈线性关系,检出限为4.6×10-7 mol/L,并可用于实际样中过氧化氢的检测。更多还原

【Abstract】 Metal organic frameworks(MOFs) have many advantages such as species diversity, high specific surface area and good thermal stability, etc [1]. They have shown potential prospect to be applied in many fields [2]. One kind of Cu-MOF/CNTs composites was synthesized by hydrothermal method and it was used for the preparation of chemically modified electrode. The results showed that the modified electrode had good catalytic effect to hydrogen peroxide. When the concentration of hydrogen peroxide was in 3 × 10-6~3 × 10-2 mol/L, the peak current has a linear relation with the concentration of hydrogen peroxide with the detection limit of 4.6 × 10-7 mol/L. The modified electrode could be used in the detection of hydrogen peroxide in real samples.更多还原
