| Abstract: | In this paper,a nano-Au/multi-wall carbon nanotube(Nano-Au/MWNT) modified glassy carbon(GC) electrode was fabricated,and the electrochemiluminescent(ECL) behavior of luminol on this modified electrode was investigated.Compared with the bare GC electrode,the Nano-Au/MWNT modified GC electrode can greatly enhance the ECL intensity of luminol.This kind of modification can increase 40%~50% of the active surface area of the GC electrode.The experimental results of Faradaic impedance spectroscopy indicated that t... |
