Oxygen-vacancy-mediated photocatalytic degradation of tetracycline under weak visible-light irradiation over hierarchical Bi 2 MoO 6 @Bi 2 O 3 core–shell fibers

Novel oxygen-vacancy-rich Bi 2 MoO 6 @Bi 2 O 3 core–shell fibers with 3D hierarchical structures have been successfully synthesized, and exhibit enhanced photocatalytic activities for degrading the antibiotic TC under weak visible-light illumination.
