| 摘要: | Flower-like MoS2/Ag2S/Agnanocompositeshave been elaborately designed and synthesized successfully for the first time. The prepared MoS2/Ag2S/Ag nanocomposites as a novel photocatalysts present effective photocatalytic performance for thephotodegradationof congored (CR),tetracyclinehydrochloride(TC-HCl) anddisinfectionforPseudomonasaeruginosa(P. aeruginosa). For the photodegradation of TC-HCl, the effect of the pH of the initial solution and photocatalysts dosage was investigated. Furthermore, intermediates of TC-HCl degradation were verified byGC–MSanalysis and the possible pathway of the photodegradation was also proposed. Theelectron paramagnetic resonance(EPR) technique and trapping experiments verified the electron transport path is Z-scheme system (PS-C-PS). Among them, Ag as an electron mediator enhanced the electron transmission rate and accelerated the separation efficiency of photogenerated carriers. |
