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-CNNH₂) was first prepared to catalyze the Fenton reaction. The Brönsted 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-CNNH₂ 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.

芬顿反应广泛用于消除废水处理中的有机污染物。实现目标污染物的选择性降解仍然是一个挑战。首先制备了胺功能化的铁掺杂氮化碳(Fe-CN NH ₂ )来催化芬顿反应。催化剂的布朗斯台德碱性增强以促进-NH ₂的形成。_{通过-NH 2}和H ⁺的结合在催化剂表面形成-NH ₃ ^{+来增强正zeta电位}。该催化剂对阴离子有机污染物表现出快速、彻底的选择性降解。同时,Fe-CN的催化活性NH ₂的去除率高于报道的四环素（TC）去除率，总有机碳（TOC）去除率达到84%。该催化剂对污染物表现出很强的解毒能力。这项研究为制备选择性降解有机污染物的高效催化剂提供了一种新的设计策略。
