文摘

Z-scheme BiO1-xBr/Bi2O2CO3 photocatalyst with rich oxygen vacancy was developed. Z-scheme BiO1-xBr/Bi2O2CO3 photocatalyst could improve the photocatalytic efficiency. Oxygen vacancy serves as electron mediator to promote the charge carriers separation. A possible mechanism of the improved photocatalytic efficiency is proposed.
