• # Abstract

In this work, a novel and enhanced electrochemical sensor based on Na$^+$-doped g-C$_3$N$_4$ was constructed for the detection of phenol. First, the g-C$_3$N$_4$ was formed through polymerizing melamine under 520$^{\circ}$C. And then the Na$^+$-doped g-C$_3$N$_4$ was fabricated by a simple wet chemical method. The electrochemical sensor was constructed by modifying the carbon paper with the resulting Na$^+$-doped g-C$_3$N$_4$. The morphology, chemical compositions and structure of Na$^+$-dopedg-C$_3$N$_4$ were characterized by scanning electron microscopy, transmission electronic microscopy, energy-dispersive X-ray detector and X-ray diffraction. The Na$^+$-doped g-C$_3$N$_4$ electrode was used for the cyclic voltammetry and amperometric response detection of phenol in a 0.1 M phosphate buffer (pH 9.0). Under the optimal conditions, the prepared sensordisplayed good performance for the electrochemical detection of phenol with a wide linear range of 1–110 $\mu$M, as well as low detection limit of 0.23 $\mu$M.
