The plasma Bi/Bi 2 MoO 6 /TiO 2 composite nanofibers were prepared via a facile one-step solvothermal method, using electrospun TiO 2 nanofibers as substrate, and glucose as reducing agent. The photocatalytic activity of the samples were evaluated by photodegradation of rhodamine B and 4-chlorophenol solution under visible light irradiation. The results showed that metal Bi nanoparticles were generated on the surface of Bi 2 MoO 6 nanosheets via reduction of Bi 3+ in situ by glucose, meanwhile grew on the TiO 2 nanofibers surface. The photocatalytic activity of the Bi/Bi 2 MoO 6 /TiO 2 composites nanofibers can be further improved by depositing metallic Bi owing to its surface plasmon resonance. The RhB catalyzed by the sample was degraded by 95.8% under visible light irradiation for 50 min, and the degradation efficiency remained over 92% after 5 cycles while the 4-CP was degraded for 68.8% under visible light irradiation for 180 min. All above results suggest that the photocatalysts have good photocatalytic activity and stability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
