Abstract
Abstract: Graphene/Carbon Nanotube hybrid films modified glassy carbon electrode (GN-CNT/GC) was fabricated as electrochemical sensor for the sensitive and rapid determination of rutin. The electrochemical behaviors of rutin at the GN-CNT/GC have been investigated. Rutin can generate a pair of well-defined redox peaks at the GN-CNT/GC located at 0.450 V (Epa) and 0.409 V (Epc). Compared with graphene modified glassy carbon electrode (GN/GC) and carbon nanotube modified glassy carbon electrode (CNT/GC), GN-CNT/GC showed a higher catalytic activity toward rutin. This result indicates that the GN-CNT hybrid films as a modifier strengthens the adsorption of rutin. Cyclic voltammetry (CV), different pulse voltammetry (DPV) and transmission electron microscopy (TEM) were employed to characterize the electrochemical sensor and hybrid films. Under the optimal conditions, the oxidation peak current is linear to the rutin concentration over the range of 2.0×10-7-6.0×10-5 M and the detection limits were 1.0×10-7 M.
