▎ 摘　　要

In this study, the electrospinning method was used to prepare graphene oxide/titanium dioxide (GO/TiO2) nanofibers with different contents of GO as photocatalysts used to degrade methylene blue (MB). Photocatalytic studies suggested that the GO/TiO(2)composite nanofibers showed higher photocatalytic activity than pure TiO(2)nanofibers under visible and ultraviolet light irradiation and the well-dispersed GO with the content even high as 7 wt%. In addition, the 7% GO/TiO(2)nanofibers could almost completely decolor the MB solution that after 90 min under ultraviolet light irradiation, and it can degrade approximately 62% of the MB solution after 4 h under visible light irradiation. Finally, the photocatalysis mechanism for the GO/TiO(2)is also discussed.
