Amine functionalized Fe doped g-C3N4 for rapidly and thoroughly selective degradation of anionic organic pollutants

The Fenton reaction was widely used for the elimination of organic contaminants for treating wastewater. It is still a challenge to realize the selective degradation of target pollutants. Amine functionalized Fe-doped carbon nitride (Fe-CN-NH2) was first prepared to catalyze the Fenton reaction. The Bro center dot nsted alkaline of the catalyst was enhanced for the -NH2 formation. The positive zeta potential was strengthened by the formation of -NH3+ at the catalyst's surface through the combination of -NH2 and H+. The catalyst exhibited rapid and thoroughly selective degradation for anionic organic pollutants. Simultaneously, the catalytic activity of Fe-CN-NH2 was higher than those reported for tetracycline (TC) removal, and total organic carbon (TOC) removal reached 84%. The catalyst showed a strong detoxification ability for the pollutants. This study provides a new design strategy to prepare highly efficient catalysts for the selective degradation of organic contaminants.

Automated summary

This study prepares amine functionalized Fe-doped carbon nitride catalyst for the selective degradation of organic pollutants in the Fenton reaction. The catalyst enhances its cationic property by forming -NH2 under alkaline conditions and exhibits rapid and thorough degradation effect.
