Bagasse pith thin carbon network loaded Fe-N monatomic catalyst as well as preparation method and application thereof

The invention relates to a bagasse pith thin carbon network loaded Fe-N monatomic catalyst and a preparation method and application thereof, and belongs to the technical field of catalysts.The bagasse pith serves as a carbon source, mass wall separation of bagasse pith cells and anchoring of iron are achieved through a two-step hydrothermal reaction, and the bagasse pith thin carbon network loaded Fe-N monatomic catalyst is finally obtained. According to the obtained catalyst, iron is loaded in a bagasse pith thin carbon network through a Fe-N-C coordination structure, the obtained catalyst has a good photocatalytic decomposition effect on tetracycline antibiotics, a new insight is provided for exploration of photodegradation of phenolic substances through a monatomic catalyst, and meanwhile high-value utilization of bagasse pith is achieved. 本发明涉及一种蔗髓薄碳网负载Fe-N单原子催化剂及其方法制备与应用，属于催化剂技术领域，本发明以蔗髓作为碳来源，通过两步水热反应，实现蔗髓细胞的质壁分离和铁的锚固，并最终获得一种蔗髓薄碳网负载Fe-N单原子催化剂，所获得的催化剂，铁以Fe-N-C的配位结构负载在蔗髓薄碳网中，所得的催化剂对四环素类抗生素有较好的光催化分解效果，不仅为单原
