Description
Summary:Covalent triazine frameworks (CTFs) are an exciting new class of porous organic materials with excellent chemical stability and easy functionalization. In recent years, CTFs have gained increasing attention in electrochemical detection of environmental contaminants. Herein, a novel CTF material was successfully synthesized by the solvothermal condensation of 1,3,5-tris-(4-aminophenyl)triazine (TAPT) and 2,3,6,7-tetrabromonapthalene dianhydride (TBNDA) for determination of 1-naphthol in water. The obtained CTF, denoted here as TATB, comprised uniformly sized spherical particles (diameter 0.5–2 μm) with a highly conjugated structure that benefited electron transfer processes when applied to a glassy carbon electrode (GCE). A TATB/GCE working electrode showed excellent catalytic activity for the oxidation of 1-naphthol, with the oxidation peak current being directly proportional to the 1-naphthol concentration in the range of 0.01–10.0 μM, with a detection limit of 5.0 nM (S/N = 3). In addition, the TATB/GCE sensor possesses excellent reproducibility, sensitivity, and selectivity for 1-naphthol determination in aqueous solution. This work highlights the potential of CTFs in electrochemical sensing, whilst also demonstrating a sensitive and stable sensor platform for 1-naphthol detection in water.
