Construction of silver/graphitic-C3N4/bismuth tantalate Z-scheme photocatalyst with enhanced visible-light-driven performance for sulfamethoxazole degradation

Constructing Z-scheme photocatalysts is an effective way to enhance the photocatalystic performance by efficiently strengthening the charge separation. Meanwhile, the high reduction activity of conduction band electrons and oxidation activity of valence band holes are retained. In this work, we fabricated a novel ternary Ag/g-C3N4 (CN)/Bi3TaO7 (BTO) photocatalyst with remarkable visible-light response capability through the method of combining...
