Abstract: A highly-uniform nanofiber of Ag-graphene-TiO2 was successfully fabricated by the electrospinning technique, which exhibited significantly increased visible light absorption (λ > 420 nm) and improved photocurrent response. The Ag nanoparticles (AgNPs) and graphenes located in TiO2 fibers induced an increase in the visible-light photocurrent response. The photocurrent density of Ag-graphene-TiO2 fibers is 4-fold higher than the pristine TiO2 fibers under visible light. The increased photocurrent response in visible light region is resulted from the strong interaction between TiO2 fibers and graphene sheets, as well as the localized surface plasmon resonance of AgNPs.
