Novel camellia-structured Z-scheme BiOBr/g-C3N4/Bi2O2CO3 was simply prepared by a hydrothermal method and photodegraded Rhodamine B under visible light within 60 min with much higher degradation efficiency (98%) contrasted with pure BiOBr, g-C3N4 and Bi2O2CO3. Radical trapping experiments exhibited the main reactive species (·O2-) during degradation process. The formation of Z-scheme heterojunction improved rate of charge separation, enhanced absorption of visible light and thus promoted the photocatalytic activity. The Z-scheme heterojunction is a promising material for the removal of dye in effluents.
