Multiwalled Carbon Nanotubes Coated with Nitrogen–Sulfur Co-Doped Activated Carbon for Detecting Fenitrothion

A nonenzymatic electrochemical sensor is drop casted for sensitive and specific fenitrothion (FT) detection, where a glassy carbon electrode (GCE) is modified by depositing an ink containing nitrogen–sulfur co-doped activated carbon-coated multiwalled carbon nanotubes (NS-AC-MWCNTs). We provide a method for NS-AC-MWCNT synthesis as follows. First, polypyrrole is coated on multiwalled carbon nanotubes (PPy-MWCNT). Then, the PPy coating is …
