Oxygen-vacancy-engineered BiO 2− x /Bi 2 O 3 heterojunctions for synergistic photo-tribocatalytic degradation and broad-spectrum antibacterial performance

Under photo-tribocatalysis, BiO 2− x /Bi 2 O 3 achieves 99% degradation of MB within 2 h and exhibits strong broad-spectrum antibacterial activity, because of the boosted charge separation via O V engineering and heterojunction structure design.
