Construction of Fe3O4/MoS2-O/biochar heterostructure with visible light-driven photodegradation of levofloxacin and sterilization activity: efficiency, reaction pathway, and mechanism

There are few studies on using spent mushroom substrates to fabricate magnetic photocatalysts. In this paper, biochar (BC) was coupled with Fe3O4/MoS2-O to form a magnetic heterostructure (Fe3O4/MoS2-O/BC) using the hydrothermal method. Under the visible light irradiation, Fe3O4/MoS2-O@BC-4 exhibited a high level of photocatalytic activity in the degradation of Levofloxacin (LVX), achieving approximately 90.64
