摘要

The visible light-responsive photocatalyst Ag-AgBr@Bi20TiO32 exhibited both high photocatalytic activity and antibacterial activity. To achieve the efficient immobilization of Ag-AgBr@Bi20TiO32, coaxial electrospinning technology was adopted to fabricate the novel multifunctional PAN/Ag-AgBr@Bi20TiO32 electrospun fiber mats. The characterization results indicated that the surface of each electrospun fiber was uniformly covered with the Ag-AgBr@Bi20TiO32 photocatalyst. The loaded Ag-AgBr@Bi20TiO32 endowed the composite fiber mats with an excellent photocatalytic activity and recyclability for the degradation of the herbicide isoproturon under visible light irradiation. Meanwhile, it showed efficient antibacterial activity against both the Gram-positive bacteria S. aureus and Gram-negative bacteria E. coli due to the synergistic effect between the silver, which has innate antibacterial activity, and active species, which have a strong oxidation ability, generated on the surface of the photocatalyst. Given the above research results, the flexible PAN/Ag-AgBr@Bi20TiO32 electrospun fiber mats would have potential applications in the water/air purification field and biochemical protective clothing.
