Fluorine functionalized graphitic carbon nitride for iron(III) sensing and methylene blue photodegradation

Year: 2024

Type: article

Abstract: This study synthesizes graphitic carbon nitride (g‐C3N4) and fluorine‐doped graphitic carbon nitride (Fgcn) nanosheets with different fluorine weight percentages, and their potential for fluorescence detection of Fe3+ ions and photocatalytic degradation of methylene blue (MB) using solar light is then investigated. The samples demonstrated extraordinarily sensitive and selective Fe3+ detection at a limit of detection of 0.48 µM and a limit of quantification of 1.46 µM. Moreover, compared to the pure g‐C3N4, the Fgcn demonstrated a faster rate of photocatalytic degradation of the MB dye. The adjustable band gap, increased number of short‐lived species, two‐dimensional nanostructure, and reduced lattice strain all contribute to the increased photocatalytic activity of Fgcn samples. This study shows that the use of flourine‐doped g‐C3N4 can improve the selective detection of Fe3+ ions as well as the photocatalytic degradation of methylene blue when exposed to solar light.
