Abstract
The effective separation of photogenerated carriers is still a key problem to be overcome in the preparation of efficient green photocatalysts. In this work, A novel ternary composite LaFeO 3/g-C 3N 4/Ag 3PO 4 (LgA) with dual Z-scheme heterojunction structure photocatalyst was constructed by combining LaFeO 3 with excellent photoelectric conversion rate and Ag 3PO 4 with high-quantum yield on the surface of g-C 3N 4 by electrostatic attraction and in-situ co-precipitation. The serial characterization confirmed that there were close heterojunction interfaces and well-matched band structures among them, which was conducive to improving the separation efficiency of photogenerated electron-hole pairs. The photocatalytic results showed that the photocatalytic degradation performance of LgA-4 composites for ciprofloxacin hydrochloride (HCIP) was significantly superior to that of g-C 3N 4, LaFeO 3, Ag 3PO 4 or their binary composites, and the degradation efficiency could reach 90.2 %, which could be mainly attributed to the construction of dual Z-scheme heterojunction with large valence bands oxidation surface, improved the light absorption capacity and promoted the separation of photogenerated electron-hole pairs (e −-h + ). LgA-4 also had good stability and efficient universality. Furthermore, the photocatalytic mechanism of HCIP photocatalytic degradation by LgA-4 heterojunction was particularly discussed according to the results of characterization, free radical quenching and ESR experiments. The potential degradation pathways for HCIP by LgA-4 were proposed as well based on the degradation intermediates detected by Ultra-high Performance Liquid Chromatography-Mass Spectroscopy (UPLC-MS), HCIP degradation was confirmed a process of reduced ecotoxicity. These results provided a facile pathway for the preparation and application of high efficiency photocatalysts in water pollution control.
