摘要: In this study, the Ag3PO4/SnO2 heterojunction on carbon cloth (Ag3PO4/SnO2/CC) was successfully fabricated via a facile two-step process. The results showed that Ag3PO4/SnO2/CC exhibited remarkable photocatalytic performance for degradation of Rhodamine B (RhB) and methylene blue (MB), under visible light irradiation. calculated k values RhB MB over are 0.04716 min−1 0.04916 min−1, which higher than those reactions Ag3PO4/SnO2, Ag3PO4/CC SnO2/CC, respectively. enhanced activity could mainly be attributed to improved separation efficiency photogenerated electron-hole pairs, after formation heterojunction. Moreover, with large specific surface area excellent conductivity used as substrate, helped increase contact dye solution photocatalysts rapid transfer electrons. Notably, when compared powder catalyst, catalysts supported easier quickly recycle from pollutant solution, thereby reducing probability recontamination.
