Enhanced photocatalytic activity of TiO2-CdS composite nanofibers under sunlight irradiation**

Pure TiO2 and TiO2-CdS composite nanofibers were synthesized through electrospinning technique. The effects of various levels of CdS loading in a TiO2 nanofibers composite were investigated. Pure TiO2 nanofibers were polycrystalline with an anatase phase, whereas anatase and wurtzite phases coexiste...
