Electrochemical Analysis of Nicotine Based on Multi-Walled Carbon Nanotube/Graphene Composite

摘要

In this article, multi-walled-carbon nanotube/graphene hybrid (MWCNT-G) was prepared by directlyadding graphene powder to the surface functionalized multi-walled carbon nanotubes (MWCNT)dispersion. The morphology of the MWCNT-G was observed using SEM and TEM. Observationfound the MWCNT-G represented a network morphology, which is beneficial for the electrochemicalreaction. Therefore, the MWCNY-G was used for commercial electrode surface modification. Theelectrochemical performance of the modified electrode was tested by electrochemical determination ofnicotine.
