Fabrication of 2D/2D Z-scheme highly crystalline carbon nitride/δ-Bi2O3 heterojunction photocatalyst with enhanced photocatalytic degradation of tetracycline

•2D/2D HCCN/BO Z-scheme heterojunction was synthesized by a solvothermal method.•The formation of 2D/2D heterojunctions shortens the carrier distance from bulk to the surface and provides abundant active sites.•The transmission path of photo-induced electrons follows Z-scheme that can effectively re...
