Summary: | The electrocatalytic study of ascorbic acid using single-walled carbon nanotube/tungsten oxide (SWCNT/WO3) modified glassy carbon electrode prepared by mechanical attachment was conducted. The oxidation peaks obtained indicate that the SWCNT/WO3-modified glassy carbon electrode has good electrochemical behaviour in terms of sensitivity. The mechanical attachment of a SWCNT/WO3 composite on the glassy carbon electrode (GCE) surface enhanced the oxidative current when compared to the WO3-modified electrode and bare GCE. The oxidation peak of SWCNT/WO3-modified electrode was considerably enhanced by 2.5 times with about a 230 mV peak shift towards a lower potential when the SWCNT/WO3-modified electrode was used in comparison with a bare GCE. |
