A novel Sn2Nb2O7/defective carbon nitride heterojunction photocatalyst: preparation and application for photocatalytic oxytetracycline removal

A traditional type-II Sn2Nb2O7/defective carbon nitride (HCN) heterojunction structure photocatalyst was constructed aiming to enhance the photocatalytic property of pyrochlores Sn2Nb2O7. Experimental analysis verified that a built-in electric field was...
