A process to fabricate a kind of novel micro-nano scaled TiO2 /CuS composite fibers by electrospinning technique and chemical precipitation method was developed in the present study.The microstructures and photoelectronic properties of the fibers were characterized using SEM,FT-IR,UV-vis and fluorescence spectroscopy.The results revealed that the TiO2 portion in the composite fibers was a mixture rutile and anatase phases while TiO2 and CuS had been fully composite.The fibers had smooth surface with a diameter of 50-300 nm.Comparing with pure TiO2 fiber,the TiO2 /CuS micro-nano-scaled composite fibers exhibited a strong absorption in the visible light region and the efficiency of photo-induced charge separation were enhanced.This composite system is of widely potential applications in the areas such as solar cells,supercapacity,photocatalysis,etc.
