A novel electrochemical sensor based on N,P-doped porous carbon materials derived from covalent organic frameworks for highly sensitive determination of 4-aminophenol and acetaminophen

A phosphoronitrile-based COF (HP-COF) was employed as the precursor to acquire N,P-doped porous carbon materials by carbonization. A novel electrochemical sensor HP-COF-C-600/CS/GCE could detect ACOP and 4-AP simultaneously and sensitively.
