摘要：

The combination of fullerene (C-60)-functionalized multiwalled carbon nanotubes (CNTs) and ionic liquid (IL) that yields a nanostructured modified electrode formed a novel kind of structurally uniform and electrocatalytic activity material. The modified electrode was characterized by different methods. It was found that the nanocomposite film of C-60-CNT/IL on glassy carbon electrode exhibits excellent electrocatalytic activity towards catecholamines, including norepinephrine (NE), isoprenaline (IP) and dopamine (DA) oxidation, resulting in a marked lowering in the peak potential and considerable improvement of the peak current as compared to the electrochemical activity at the bare glassy carbon electrode. The improvement of electrochemical response to catecholamine oxidation was found at modified electrode, revealing the synergetic effect of C-60-CNT and IL Furthermore, the catecholamines were successfully used for the determination of catecholamines in real samples.
