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

Abstract

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...

Synthesis and application of type-II heterojunctions based on CdS and g-C3N5 for efficient photocatalytic degradation of antibiotics

“…In order to investigate the photocatalytic mechanism of the 3SCN composites, 1,4-benzoquinone (BQ, O 2 À trapper), isopropanol (IPA, OH trapper) and ethylenediaminetetraacetic acid disodium (EDTA-2Na, h + trapper) were used as active species scavengers. 63,64 In Fig.…”
