Facile synthesis of flower-like microsphere MnS/BiVO4 p-n heterojunction with enhanced photocatalytic activity

Novel flower-like microsphere [Formula: see text]-MnS/[Formula: see text]-BiVO 4 [Formula: see text]-[Formula: see text] heterojunction photocatalyst has been successfully synthesized by a facile hydrothermal and annealing method. The morphology and optical properties of composite materials were characterized with multiple techniques. The photocatalytic efficiency of MnS/BiVO 4 was evaluated by degradation of Methylene blue (MB) and Ciprofloxacin (CIP) under visible light. Radical trapping experiments confirmed that [Formula: see text] was the main active species to the degradation of organic contaminant in the system.
